TRANSCRIPT
The Aerospace Engineering Department is strong and vibrant. Our undergraduate enroll‐ment remains at near all‐time high levels. Simultaneously, research activity has been increasing. These factors have positioned the Department to grow within the College. This growth can be seen in the numbers of faculty, student projects and discretionary resources. Our Department has historically been very active in the areas of test and experimenta‐tion. Computational simulations of increasing fidelity can be used, in some cases, to sub‐stantiate or even replace traditional experi‐
mental based studies, or to provide a measure of verification. How we incorporate simulation into the curriculum, without sacrificing theoretical foundations or hands‐on experi‐ences, is being actively pursued. In this issue we describe a sampling of our research efforts in the area of simulation. These areas cover fluid mechanics, propulsion, solid mechanics and automated meth‐ods to improve design processes.

The Plasmadynamics and Electric Propulsion Laboratory (PEPL):
At the Forefront of Advanced Spacecraft Propulsion Research
International Electric Propulsion Conference (IEPC) Professor Alec Gallimore chaired the 31st International Electric Propulsion Conference, which was held 20‐24 Sept. 2009. The IEPC is the premiere conference of electric propulsion (EP) and is held every other year. Last year's conference brought together more than 270 researchers, developers, and managers from 17 countries. The IEPC also showcased some of the
Department’ capabilities, including PEPL, and student projects such as cubesats and C‐9 micro‐gravity payloads associated with the Student Space Systems Fabrication Laboratory (S3FL).
Brief History of PEPL The 6‐m by 9‐m vacuum chamber now referred to as the Large Vacuum Test Facility (LVTF) was built by the Bendix Corporation to test lunar rover proto‐types, spacesuits, and other devices in 1962. In 1982, the facility was do‐nated to the University of Michigan, and in 1992, Professor Alec Gallimore joined the Aerospace Engineering Department and started PEPL. Since then, PEPL has tested 30 EP devices, running the full gamut of technologies includ‐ing: arcjets, magnetoplasmadynamic thrusters, nanoparticle thrusters, ion thrusters, and Hall thrusters. This expertise and experience has led to the development of PEPL’s own line of magnet‐layer Hall thrusters, developed jointly with NASA and the US Air Force. PEPL also routinely engages in the qualification of flight Hall thrusters, some of which are now operating in space.
The research and teaching activities conducted at PEPL can have a much broader and lasting impact on the human race. Professor Gallimore (pictured at left) remarks, “We offer a way of finding life elsewhere, and therefore, a step closer to finding our place in the universe. And when humanity decides to have a meaning‐ful presence on another world one or more generations in the future, know that it is the work we do here and now that will allow this future to come.”

Three
Generations
of Aeros
The Criel family has witnessed much of the history of our department, including the various locations of the department in: i) East Engineering on central campus, now East Hall; ii) the Aerospace Building, now the Engineering Programs Building on north campus; and finally, iii) the François‐Xavier Bagnoud Building, also located on north campus. Harry’s class size was about 10 (mid‐1950s) while Ben’s class was over 100 (late‐2000s) students. For Harry, the north campus was merely a field where “a” wind tunnel was being built, that is now the location of most of the Department. There have also been interesting pedagogical changes across the three generations. Harry’s only program choice was Aeronautics and he was in the first class that did not have to take a steam‐engine course. Harry could choose between several specializations: Aerodynamics, Propulsion, Structures, or Instrumentation (Control Systems), and there were separate propulsion, structures, and wind tunnel labs. By the late 1970s the Aero program offered, for Todd and Ben, the choice to emphasize either Aeronautics or Astronautics by their selection of a senior design course; their labs were integrated into two courses.
Each generation has had memorable classes or interactions. For Harry, it was automatic control systems with Professors Bob Howe and the Gilbert twins, Elmer and Edward, where they used analog computers. Harry also recalls the study of oscillations of non‐linear systems with Professor Lawrence Rauch—one of the most difficult classes, but also one of the most useful—and he lauded J.D. Shetzer as being an excellent teacher. The Department had a flight test course at Willow Run Airport that involved going up in an airplane to check out airspeed indicator; unfortunately, due to weather conditions, the class averaged only two flights per semester. Todd took introduction to Aero from Wilbur Nelson where they visited the Ann Arbor Airport, and he too was able to fly, while Professors Bill Powers and Don Greenwood fostered his interest in controls and simulation. Ed Lesher’s Airplane design class—where everyone had to do everything—was an all‐encompassing experience that required a full report on the last day of class, challenging students’ skills in time management. Todd also recalls going into the chairman’s office (Bob Howe) to request courses for the next year, and perhaps most memorable was when he visited, unannounced, 25 years after graduation, and Margaret Fillion, former graduate student services assistant for many years, recog‐nized him immediately as Harry Criel’s son, and recalled when his father attended school. Ben’s most memorable classes involved propulsion with Professors Werner Dahm and Jim Driscoll. The Criel’s share common technical genetics in that all three have some connection with testing, and missile systems. Harry spent 22 years at the Cornell Aeronautical Laboratory in Buffalo, New York (now Calspan), where he worked in the systems analysis group on the FAA air traffic control program, lunar program, penetration aids, and electronic counter measures. Todd has been at the Sandia National Laboratories for 24 years working on missile simulations, target deployment, and rockets. Ben recently started at Edwards Air Force Base on jammers and radar warning receivers.
Each left Michigan with at least one degree and his future wife.

Three Generations in Aerospace Engineering: The Criel Family
Three generations of the Criel family (from left to right): Harry Criel BSAE 1954 and MSAE 1955, Todd Criel BSAE
1978 and MSAE 1979, and Ben Criel BSAE 2008.
Their current projects cover a wide range of topics, such as: (i) an Air Force Research Laboratory‐funded collaborative center on computational aero‐science, (ii) a Department of Defense‐funded Multidisciplinary University Research Initiative (MURI) project on flexible and flapping wing aerodynamics, (iii) a NASA‐funded Constellation University Institute Program for Moon‐Mars exploration endeavors, and (iv) a Department of Energy and General Motors‐funded project on advanced battery coalition on drive trains, as well as several individual grants. With this support, the group enjoys collabo‐ration with a number of researchers from UM and elsewhere.
Computational Modeling Techniques Wei Shyy
Professor Shyy’s research group focuses on a broad range of computational and modeling techniques address‐ing various challenges arising from fluid dynamics, heat/mass transfer, bio‐inspired flight, fluid‐structure interactions, battery technologies, design optimization, interfacial transport, combustion, materials processing, and multi‐scale transport processes.
The group’s interest encompasses fundamental research and engineering application, including (i) development of original and novel numerical and modeling techniques for multidisciplinary problems related to thermo‐fluid dynam‐ics; (ii) computational and modeling techniques typically developed to a point that they form a complete capability to tackle original physical issues; (iii) consistent emphasis on close collaboration between theory/computation and experiment; (iv) extension of scientific research to address engineering issues arising from optimization, assessment and design tool development.

Multi‐scale computational modeling of materials is an emerging area of research. A variety of models are used, beginning from quantum mechanics at the scale of chemical behavior (Angstroms); moving on to molecular dynamics at the scale of defects (nanometers) and contin‐uum mechanics at microstructural scales (micrometers and above). Professor Sundararaghavan's group develops and applies these techniques for the study of engi‐neering materials, especially those used in extreme environments that involve conditions that cannot be established in the laboratory. The group has developed novel computational "materials‐by‐
design" methodologies for tai‐loring microstructure‐sensitive properties in metallic polycrys‐tals and for identifying new alloy structures in performance‐critical applications. Multi‐scale models are used to predict composite material degradation in high tempera‐ture, oxidizing environments. Such models would help predict the rate of property degradation and aid in design of improved high‐performance composite structures for a variety of applications (structural elements in heat shields, gas turbines). Professor Sundararaghavan recently won the National Science Foundation (NSF)
CAREER award for his project on computa‐tional design of low‐cost magnetostrictive alloys for energy harvesting, tracking, and sensing devices.

Inside Story Headline
Computational Analysis of Hypersonic Capsule
Aerothermodynamics Iain Boyd
A key component of NASA’s exploration mission involves hy‐personic entry of capsules into the atmospheres of Earth and Mars. Since ex‐perimental study of hypersonic flows is both technically chal‐
lenging and expensive, the analy‐sis of planetary entry relies heavily on computer simulation. In re‐
search funded by NASA’s Aero‐nautics Research Mission Direc‐torate, Professor Boyd’s group is developing a computer simula‐tion capability for detailed analysis of the aerodynamics and heating of a hypersonic cap‐sule. The computer code solves the Navier‐Stokes equations of fluid flow coupled with terms describing the finite rates of thermo‐chemical relaxation. The code runs on a parallel cluster of
computer processors. The student performing the work, Aero Ph.D. Student, Hicham Alkandry, spent the summer of 2009 at NASA Langley Re‐search Center interacting with researchers engaged in per‐forming similar work for cur‐rent NASA projects including the CrewExploration Vehicle and Mars Science Laboratory.

element method, to serve as a research platform for practical error estimation studies. This solver combines three decades of finite volume research with extensive error estimation theory associated with finite elements. When only a handful of engineering outputs are of interest, the computa‐tional mesh can be tailored to predict those outputs well. The process requires solutions of auxiliary “adjoint” problems for each output that provides information on the sensitivity of the output to discretization errors in the mesh. This information guides mesh adaptation, so that after a few iterations of the process, the engineer receives an accurate solution along with error bars for the outputs of interest. In particular, for many equations, including Navier‐Stokes, there exists one “free” adjoint solution that is related to the amount of entropy generated in the flow. This adjoint is obtained by a simple variable transformation and is there‐fore quite cheap to implement. Ongoing research is investigating the applicability of both the entropy adjoint and the traditional output adjoint, to practical aerospace engineering simulations.
Computational Simulations Chris Fidkowski
The accuracy of aerospace computational simulations depends heavily on the amount of numerical error present, which in turn depends on the allocation of resources, such as time step and mesh size distribution. Estimation of this error and the determination of the optimal mesh resolu‐tion for its reduction are two underlying themes of Professor Fidkowski's research. His group is designing general algorithms for error estimation, uncertainty quantification, and mesh adaptation. One project involves development of a new fluid dynamics solver, using a discontinuous finite
Reynolds‐averaged Navier‐Stokes solutions for two‐ and three‐dimensional transonic flows using a discon‐tinuous finite
element method.

Professor Martins’ research focuses on applying multidiscipli‐nary design optimization (MDO) to aircraft configurations. Professor Martins' group has strong connections with Bombardier Aerospace and universities, such as Stanford and MIT. The group’s research is motivated by the vision that engineering design, and aircraft design in particular, will be performed in MDO environments where it is possible to perform the design optimization of complex engineering systems using computational tools. This will enable a relatively small team of engineers to perform the preliminary design of a new system in a period of one to two weeks, instead of the several months currently required by a much larger team of engineers. Two main aspects of this research can be identified: i) Numerical optimization algorithms: New MDO algorithms and software have been developed by Professor Martins' research group. These have been developed in a general way, such that they can be used for any MDO application, and ii) Specific applications: Although the algorithms are general, the group specializes in aerospace applications. The group has pioneered the development of coupled sensitivity analysis using adjoint methods and its application to the aerostructural design optimization of aircraft wings. In addition to aircraft design applications, the group is involved in a project that aims to design quiet wind turbines using the high‐ fidelity aerostructural
Radiative shocks occur in a number of situations, ranging from laboratory experi‐ments for inertial fusion to supernovae. The Department of Energy has funded the Center for Radiative Shock Hydrodynamics (CRASH), which is led by the University of Michigan and includes collaboration with Texas A&M University. The CRASH effort is developing simulation tools and experiments to study radiative shocks, and is using uncertainty quantification techniques to assess the predictive capabilities of the simulation tools, and to improve on them.
This class of flows is challenging to model, because the flows contain very strong shocks (> 100 km/sec) and strongly couple the gas dynamics and the radiation transport. Radiation‐transport phenomena occur at the speed of light, and the codes must account for ions and electrons in the flow equations, so the problems exhibit vastly disparate scales. The code developed to carry out the calculation uses adaptive grids and is run in parallel on hundreds of processors.

Retrospective Cost Adaptive Control
Dennis Bernstein
Walking, running, and bicycling all have one thing in common with piloting an aircraft, namely, they use feedback control. All of these activities require real‐time sensing, processing, and actuation to achieve objectives such as stabilization, com‐mand following, and disturbance rejection. A major goal for Professor Bernstein’s group is to achieve these objectives with a computer in the loop to assist the human or, in the case of autonomous flight vehicles, to replace the human completely.
Humans instinctively perform sensing, processing, and ac‐tuation. For aero‐space applications, sensing is performed by gyroscopes, accel‐erometers, and GPS. Actuation is per‐formed by engines and control surfaces in fixed‐wing aircraft, by the swash‐plate assembly in rotor‐craft, and by thrust‐ers, wheels, and magnetic devices in spacecraft. Process‐ing is performed by on‐board computers
that collect sensor data, implement control algorithms, and send instructions to the actuators.
Engineering a reliable, high‐performance control system for a flight vehicle is a major undertaking, which must take into account the performance objectives, the vehicle dynamics, and the hardware limitations. The benefits of adaptive control include the ability to operate under unexpected conditions, such as flight anomalies, as well as the ability to control complex systems.
His group began developing adaptive control algorithms in the late 1990s. Research on adaptive noise control led to the development of a new digital adaptive control algorithm based on retrospective cost optimization (RCO). The idea behind RCO is to update the control law by minimizing a retro‐spective cost function based on historical data. RCO is being studied for several applications, including emergency flight control under NASA’s Integrated Resilient Aircraft Control (IRAC) program, flight control for Raytheon Missile Systems, flow control, and automotive control in a project with Ford.

2009 Alumni Merit Award:
Elmer G. Gilbert Elmer G. Gilbert is a Professor Emeritus in the Department of Aerospace Engineering at the University of Michigan. He started as an Assistant Professor in 1957 in the Department of Aerospace Engineering and rose through the ranks to Profes‐sor, retiring in 1994. He holds three degrees from the Univer‐sity: B.S. (1952) and M.S. (1953) degrees in Electrical Engineer‐ing and a doctorate in Instrumentation Engineering (1957), a systems program in the then Department of Aeronautical
Engineering. Over his long career at Michigan he has published extensively in peer‐reviewed journals, obtained patents on a variety of computer and control devices, and played an active role in department teaching and curriculum development. He enjoyed working with his 24 doctoral students. He held visiting appointments at the United States Air Force Academy, the Johns Hopkins University, the University of Minnesota, and the National University of Singapore. Since his retirement he has continued, on a part‐time basis, to do research and participate in various departmental affairs. Pictured above is Elmer Gilbert and his wife, Lois Verbrugge at the 2009 College of Engineering awards dinner.
During his graduate studies Elmer was involved in the department’s analog computer and aircraft simulation research programs. This activity continued through the 1960’s, both in the department and as a consultant to Applied Dynamics International, a computer firm founded in 1957 by him and two other department professors, Robert M. Howe and Edward O. Gilbert. Up to the late 1960’s he was a key member of the Applied Dynamics group responsible for conception and development of new products.
Starting around 1960, Elmer’s activities in teaching and research emphasized the theory and applications of control systems. This is the area in which his published work has received widest recognition. It includes innovative contributions to such varied topics as: the role of observability and controllability in linear system realization theory, feedback decoupling of multivariable linear systems, input‐output representations for nonlinear differential systems, computation of optimal controls, periodic optimal control theory and its application to fuel‐efficient cyclic aircraft cruise, robot motion planning in the presence of obstacles, theory and practical implementation of feedback control strategies for systems with inequality constraints and disturbance inputs.
Elmer has received a Distinguished Faculty Achievement Award from the University of Michigan and a Research Excellence Award from the College of Engineering. He has two major societal awards for long‐term career accom‐plishments: the Institute of Electrical and Electronics Engineers (IEEE) Technical Field Award in Control Systems for pioneering contributions to linear state space theory and its applications, the American Automatic Control Council Richard E. Bellman Control Heritage Award in recognition of a distinguished career in automatic control. He is a Fellow of the IEEE, a Fellow of the American Association for the Advancement of Science, and a member of the Johns Hopkins University Society of Scholars.

Gerard M. Faeth Memorial Lecture
“Advancing Combustion Science Through
Space and Aerospace Applications”
The 2009 Faeth lecturer was Professor Chung K. Law, the Robert H. Goddard Professor of Mechanical and Aerospace Engineering at Princeton University. Professor Law described the late Professor G.M. Faeth as a giant in combustion science and a forceful and effective advocate of its application in aerospace development. Faeth’s legacy has been an inspiration to his colleagues, including Professor Law. Law delivered the annual lecture, titled “Advancing Combustion Science through Space and Aero‐space Applications: Continuing the Legacy of G. M. Faeth,” on March 12, 2009. He discussed three fundamental problems that are of continuing interest in aeropropulsion, and that bear the footprint of Professor Faeth to varying degrees:
the combustion of droplets of high‐energy‐density fuels such as highly‐strained hydro‐carbons and metalized slurries, demonstrating that high energy content does not automati‐cally imply enhanced propulsion performance in that their combustion characteristics are
frequently complicated by the formation of
soot and particle agglomerates;
the dynamics and morphology of expanding spherical flames, covering such topics as the minimum flame radius for successful ignition, the nonlinear evolution of the flame propagation speed with stretch, the transition to cellularity induced by hydrodynamic and diffusional‐thermal instabilities, the self‐acceleration, self‐similar propagation, and transition to detonation of the resulting wrinkled flame, and the evolvement of spiral waves and target patterns over the expanding flame surface as manifestations of pulsating instability; and
the dimensional reduction of large chemical reaction mechanisms to substantially smaller sizes amenable for large‐scale CFD simulations of complex, chemically reacting flows. The intellectual challenge, beauty, and utility of combustion science will be emphasized.
Chung K. Law’s research interests cover various physical and chemical aspects of fundamental combustion phenomena, with applications to propulsion, energy, fuels, and the environment. He is a fellow of the American Institute of Aeronautics and Astronautics (AIAA), the American Society of Mechanical Engineers (ASME) and the American Physical Society (APS), a member of the U.S. National Academy of Engineering, and a past president of the Combustion Institute.
This annual lecture is made possible by the Gerard M. Faeth Memorial Fund
and the Department of Aerospace Engineering.

American Institute of Aeronautics & Astronautics (AIAA) Takes Flight in Oshkosh
A group of students from the UM Student Branch of the AIAA recently returned from a trip to the Experimental Aircraft Association's (EAA) AirVenture Oshkosh '09. The Oshkosh event is the world's largest general aviation gathering and draws an annual attendance in excess of 500,000, with over 10,000 aircraft flying in ‐ during the event, it has the busiest control tower on Earth! Oshkosh boasts countless forums, workshops, social events, air shows, and an unimaginable number of airplanes of all shapes and sizes.
The students flew out from Ann Arbor airport in two groups ‐ one in a Cessna 172 Skyhawk and the other in a Piper Saratoga. The 172 was piloted by aero grad student Andy Klesh and the Saratoga by Deano Smith (NAME). In the tradition of Oshkosh, the students camped next to their airplanes and enjoyed the camaraderie of "The World's Greatest Aviation Celebration." The highlights of Oshkosh '09 include the first U.S display of the Airbus A380 (including tours in its flight‐test configuration), the unveiling and aerial demo of Virgin Galactic's White Knight Two, the first‐ever display of the C‐5M Super Galaxy (M for modified), and the C‐17 Globemaster III. Students also enjoyed presentations by NASA X‐15 pilot Joe Engle, U.S Airways Flight 1549 Captain Chelsey "Sully" Sullenberger, and even a performance by the well known ventriloquist (and helicopter enthusiast/builder) Jeff Dunham.
Overall, the Oshkosh '09 trip was a huge success and one that AIAA hopes to make an annual occurrence. This event was the kick‐off for the forthcoming, action‐packed year of speakers, social events, and trips that the "new" AIAA has in store for the U‐M aero department. If you're not already a member,

University of Michigan Students on First Place Team in Sikorsky Intern Competition
More than 45 Sikorsky Aircraft summer interns and co‐ops descended upon Stratford, Connecticut to participate in the 4th Annual Sikorsky Research and Engineering Intern/Co‐op Summer Competition. The winning team, Team Rising Stars, led by University of Michigan Aerospace Engineering students Eryn Klager and Nick Rooney, and consisting of students from other universities, was announced on August 3rd at the final review event which included a trade show style presentation and catered dinner at the Stratford facility. The design competition is an annual event that chal‐lenges interns and co‐ops to think outside of the box as part of their sum‐mer with Sikorsky Aircraft. This year's contest dared summer interns and co‐ops to create a next generation, forward‐thinking full scale mock up of the flight controls and pilot interface of the X2 Technology Demonstrator. This is the second straight year that the winning team has included University of Michigan Aerospace Engineering students. Team Rising Stars’ winning design centered on the idea of a helicopter that is operated using various levels of neural impulse recognition, or mind con‐trol, paired with utilizing more of the human senses. When asked what their design goal was, Nick Rooney responded with “pilots these days are faced with an ever increasing work load in the cockpit, where there is a great deal of information displayed visually, to the point of information overload. Our goal was to break up how current pilots receive almost all of their information from vision, to future pilots being able to spread out where they receive their information by more effectively using hearing, speaking, touch, and vision senses. Being able to read brain waves, also called neural impulses, is something that is currently being researched, and we believed that it will become a technology that could be integrated into aircraft in the future and complement the utilization of more human
senses. Reading brain waves allows faster reactions between pilot and the aircraft.” Eryn Klager was the pilot during the demonstration by Team Rising Stars. She found the experience very valuable and said, “I found out that I am a leader and I enjoy leading. I like working in groups and helping others to reach their maxi‐mum potential through encouragement, enthusiasm, and empowerment. I gained confidence in my potential, made some great connections, and can say I flew a helicopter in front of a live audience and panel of judges with my MIND!” UM students continue be amongst the leaders and the best.

mitting various information to a balloon relay station. Thanks to sponsorship by Michigan Space Grant Consortium (MSGC) and the U of M Aerospace Department, nine students travelled to Amarillo Texas and took 2nd and 17th In the fall, the teams, guided by Steven Kipus and Professors Pete Washabaugh (AE) Professor Brian Gilchrist, (EECS) designed from the ground up two CanSats capable of transmitting GPS data through a wireless medium to a groundstation computer. The two teams, named The Hitsquad (2nd place) led by Michael Gambril and Mark Vossler, and The Blue Side of the Moon (17th place) led by Jacky Trinh and Stephanie Gowell spent the Winter and Summer semester turning their designs into reality. The teams endeavored through many engineering challenges and ultimately put together working hardware and were able to compete and win!
2009 Can Sat Competition Every year the UM typi‐cally sends two teams to the NASA CanSat Compe‐tition through the Student Space Science Fabrication Laboratory (S3FL). During the last year, two teams from S3FL executed the design, build, test, and fly
project lifecycle by competing in the CanSat competition. The task: to build a device the size of a soda can which was capable of withstand‐ing a mile high launch in a rocket while trans‐

eXtendable Solar Array System (XSAS) Microgravity Testing
The XSAS team is comprised of a collection of UM engineering students dedicated to gaining design‐build‐test experience, by developing a deployable solar array to be used on CubeSats, called the eXtendable Solar Array System (XSAS). This technology will increase CubeSat power capabilities, enabling more instruments to be flown on this emerging nanosatellite platform. XSAS utilizes a unique packaging organization to fit within the CubeSat design specifications, and a novel deployment strategy that will help extend the solar panels from an “accordion” launch configuration to a robust “space truss” on‐orbit configuration. The group is focused on analyzing the deployment dynamics of XSAS in different rotation scenarios.
The UM team is one of only 14 undergraduate groups selected to participate in NASA’s Reduced Gravity Student Flight Opportunities Program for 2010, securing a flight spot in mid‐June 2010 that will provide two days of microgravity testing. The project offers students a unique experience
with real‐world, hands‐on engineering from a multi‐disciplinary perspective, and engages the community through an outreach program to middle‐school students with the common goal of sparking excitement in Science, Technology, Engineering, and Math (STEM) fields.
The project is led by two undergraduate aerospace engineering students: Patrick Martinchek and Rachel Trabert. Team members include: Miran Al‐Haideri (BSE EECS), Daniel Becker (BSE AE), Andrew Chou (BSE ME), Kevin Dunnell (BSE AE), Arun Dutta (BSE EECS), Paul Frick (BSE ME), Kyle Hagen (BSE AE), Clark Hoffman (BSE AE), Vivek Kumar (MSE AE), Andrew Lee (BSE AE), Nathan McKay (BSE AE), Jeremy Nash (BSE CS), Michael Ramirez (BSE AE), Joshua Robinson (BSE AE), Joseph Romeo (BSE EECS), Devina Sanjaya (BSE AE), Manan Thakkar (MSE AE), and Jeffery Walters II (BSE AE). Principal Investiga‐tors for the project are Andy Klesh (AE) and Pat Senatore (AE). Faculty advisors are Jamie Cutler (AE), Brian Gilchrist (EECS), Darren McKague (AOSS), and Pete Washabaugh (AE).

National Science Foundation Enables the Radio Aurora Explorer CubeSat Mission
Weighing just under 3kg and 30cm high, RAX is the first NSF sponsored CubeSat mission. UM students, in partnership with SRI International, built RAX in response to a growing demand for smaller, more affordable satellites able to perform science missions. Once in orbit, RAX will study properties of the upper atmosphere ionosphere using a custom‐designed radar receiver.
Led by Prof. James Cutler (AE) and assisted by post‐doc researcher and Aero alumnus Andy Klesh (BSAE/BSEEE 2005, MSEAE 2006 Ph.D. AE 2009), and Aero graduate student Matthew Bennett, the team began construction with the aid of the SPRL and the EECS and MSE depart‐ments, as well as support of administrative and technical staff. Much of the spacecraft required custom‐made components, presenting a variety of challenges to the design proc‐ess. The final unit was assembled in January, 2010 and quickly underwent functional testing.
RAX successfully uploaded commands and received telemetry from a host of sensors, yielding temperature and voltage data, GPS position and velocity, spacecraft attitude (for orientation determination), and general status subsystems. The ground station software, tested over radio links, proved the ability to listen and interact with RAX remotely. Tested with a radar signal simulator, the radar receiver demonstrated data processing and compression at a reduction of over 4000 to 1. The GPS receiver was tested at Orbital Sciences Corporation in an orbit simulator, functionality at orbital velocities and altitudes. RAX passed additional testing on integration and vibration—performed at Cal Poly San Luis Obispo—by inserting the unit into a deployment mechanism and shaking it to levels that it would experience in orbit.
Physical testing, performed at UMs Student Space System Fabrication Labs (S3FL) using the thermal vacuum facility, proved equally successful. Final testing included measuring the unit’s mass properties, and determining the moment of inertia by placing RAX on a spinning platform. The team built additional testing facilities for evaluation, including an in‐house Helmholtz Cage to create and simulate the changes in magnetic fields, and a multi‐station clean room. The team is now gearing up to ensure that RAX is ready for its delivery for integration on April 2010, and its subsequent launch on May 28th from Kodiak Launch Complex in Alaska.

Human Powered Submarine
The Human Powered Submarine (HPS) is a student‐run project team that designs and builds a one‐person propeller driven submarine raced bi‐annually against teams from around the world. Students from across the College of Engineering and the Ross Business School participated to obtain hands‐on engineering experience, SCUBA dive opportunities, and contribute to a common team goal. In summer 2009, the team broke their speed record by posting 5.056 knots at the 10th International Submarine Race, placing them 4th in the category for max‐speed for one‐person propeller driven subs, and 5th overall in the competition out of 22 subs from about 5 countries. The team’s continued goal is to design and build a submarine that will challenge the one‐person human powered submarine world speed record of ~7.2 knots, by using a new and smaller foam core hull that will provide a more intuitive control system, as well as exploring the use of an experimental drive train system with variable pitch counter‐rotating propellers. The counter‐rotating propellers will help prevent rolling in the water. The variable pitch propellers will be run by a small stepper motor and serve to adjust the amount of thrust with the angle of the blade, depending on the increasing speed of the submarine. Testing on their award‐winning hull. 'Mercury' has provided the team insight on developing internal system improvements for controls, emergency buoy, ballast system, and oxygen exhaust. SCUBA dive cer‐tified students gain valuable diving experience and are passed by a per‐sonal dive with the University of Michigan’s Dive Master. Since the ISR #11 is in two years, we intend to build the hull and drive train this year, and the internal systems during the first semester of next school year, and to paint, test, adjust and perfect the submarine in Winter 2011 before the race. The HPS team has a live video feed at the Wilson Center Student Project Center website, and has been featured in USA Today, the Michigan Daily, the CoE Website Homepage, and attending Northfest, Festifall, Tech Day, and Aerofest; the team has doubled in size from the previous year. Please visit the website for live video feed and images, http://www.engin.umich.edu/hps/ or email them at [email protected].
