Message from the Chair Welcome to the 2014 issue of the KU Aerospace Engineering (KUAE) Newsletter! The past year has been a truly extraordinary one on many fronts. Countless histories were made. This last May we celebrated 70 years of tradition, memories, and achievements, and inducted two distinguished alumni/friend, Drs. SangYeop Han and Jan Roskam, into the KUAE Honor Roll. There are so many achievements, events, and activities to report. Let me start with a list of “firsts”:

A team of our undergraduate students took second place overall in a national wind power competition held in Las Vegas, NV. The team, known as Jayhawk Windustries, was one of 10 teams from universities around the country selected for the Department of Energy’s inaugural Collegiate Wind Competition. They also placed first in Testing and Design, and first in Business Plan Development.

Two KUAE graduate students, Jeremy Ims of Overland Park and William VanSkike of Norman, Okla., won prestigious National Science Foundation Graduate Research Fellowships. They will perform graduate research with Professors Z.J. Wang and Richard Hale, respectively.

One of our top undergraduate students, Ryan Endres, was selected by Aviation Week magazine as one of the winners of its newest awards program, Tomorrow’s Engineering Leaders: The Twenty20s.

The number of faculty in KUAE rose to 12 in the Fall of 2014 with the addition of Visiting Assistant Professor, Dr. Rene Woszidlo, and will further increase to 13 in January of 2015 when Assistant Professor, Dr. Huixuan Wu, joins KU. Both numbers are records in the Department’s history.

Senior and Second Lt. Julian McCafferty, a U.S. Air Force ROTC graduate, received the Chancellor John Fraser Distinguished Military Graduate Award.

Next I am thrilled to report that our students continued to repeat history by winning national and international aircraft, spacecraft and engine design competitions in 2013 and 2014:

First and Third prize in 2014 AIAA Undergraduate Team Aircraft Design Competition. Second prize in 2014 AIAA Graduate Team Aircraft Design Competition. First and Second prize awards in the 2014 AIAA, ASME, International Gas Turbine Institute (IGTI) Undergraduate Team

Engine Design Competition. Last year, a KUAE team placed second in the competition. Second and Third prize in 2014 AIAA Undergraduate Individual Aircraft Design Competition. Last year KUAE took second

prize. In 2013, KUAE won the 1st prize in the AIAA Graduate Team Aircraft Design Competition. Most of the team members were

undergraduate students. In 2013, KUAE won the 2nd prize in AIAA' s Undergraduate Team Space Transport Design Competition, and this year was

placed third. KUAE faculty continued to garner national and international attention for their outstanding achievements in research. The U.S. Board on Geographic Names announced it has registered the “Gogineni Subglacial Trench,” which acknowledges the contributions of Dr. Prasad Gogineni, the Director of the Center for Remote Sensing of Ice Sheets (CReSIS) and an AE Courtesy Professor. The study of the behavior of the world's ice sheets was highlighted by the National Science Foundation. The research results appeared on the cover of IEEE Geoscience and Remote Sensing Magazine.

I am very proud to announce that KUAE is now the highest ranking AE program in the State of Kansas according to US News and World Report. Our graduate ranking improved 8 spots to No. 27 among the best public universities, and to No. 39 overall. We are grateful that our peers noticed some of the great things taking place at KUAE.

Finally I want to thank the advisory board, faculty, staff and students that helped put together the reunion and who worked continuously to achieve the department’s mission. In particular, I would like to thank all the alumni who attended and made the reunion a great success. Without you there would be no KUAE.

Rock Chalk!

Aerospace engineering graduate students Jeremy Ims (PhD) and William VanSkike (MS) are two of six students and alumni from the University of Kansas to be awarded the prestigious National Science Foundation Graduate Research Fellowship for 2014-2015. “I’m excited and honored to receive the NSF Graduate Fellowship, not only for myself but also for KU aerospace engineering,” said Ims. “The NSF encourages interdisciplinary ideas, a perfect fit for me.” The National Science Foundation's Graduate Research Fellowship Program (GRFP) helps ensure the vitality of the human resource base of science and engineering in the United States and reinforces its diversity. “I applied for the NSF Fellowship in the category of computational science. As my research idea, I proposed adopting high-order computational fluid dynamics (CFD) for aircraft noise mitigation, developing the capability to simulate the sound of prospective aircraft so designers can hear the aircraft before building it,” added Ims. “The mesh conversion software I am currently developing in the CFD lab under the direction of Professor Wang will be the first step of my proposed project. But that proposed project can change. The beauty of the NSF is that the fellowship is not tied to a specific project, so there is flexibility for exploration and creativity.”

The program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering, and mathematics disciplines who are pursuing research-based master's and doctoral degrees at accredited US institutions. The fellowship provides $12,000 to go towards educational expenses and a $32,000 stipend for three years.

“I'm honored to have been selected as a recipient of an NSF graduate research fellowship. The fellowship will allow me to focus my research on durability and damage tolerance improvements

of composite structures used in the wind industry,” said VanSkike. “I am very thankful for the research opportunities and mentors I had as an undergraduate in the KUAE department that helped prepare me to earn this prestigious award. I am excited and looking forward to returning.”

Aerospace Engineering students claimed second place in a national wind power competition. The team, known as Jayhawk Windustries, was one of 10 teams from universities around the country competitively selected for the Department of Energy’s inaugural Collegiate Wind Competition, last May in Las Vegas.

The competition challenged students to design, fabricate, test and develop a business plan for lightweight, portable wind turbines intended to power small electronic devices. KU earned first-place awards in both the Design and Turbine Performance category and the Business Plan category.

“We did remarkably well, especially for this being the first year of the competition and our first experience with this. We’re all really proud,” said Mary Pat Whittaker, a team member and 2014 graduate in aerospace engineering.

The strong showing from KU is yet another point of distinction for the university in national aerospace design competitions. KU aerospace students continued a long-running tradition of exceptional performance in AIAA student design competitions in fall 2013, when they earned top honors in a total of four team and individual competitions.

“The success by Jayhawk Windustries says a lot about strength of our design programs. KU has a great history in aerospace design competitions, but we’ve never done anything like this,” said Whittaker. “It involved a lot of learning as we went and plenty of trial and error, but it was a lot of fun and a great experience overall.”

Jayhawk Windustries’ performance also marked another accomplishment for KU mechanical engineering students, who have competed in the Shell Eco-Marathon and other national competitions, and played a key role in developing and testing many features of the wind turbine.

The project was part of senior capstone courses taught by Rick Hale, professor of aerospace engineering and project principal investigator, and Christopher Depcik, associate professor of mechanical engineering. A total of 31 business, mechanical engineering and aerospace engineering students made up the fall semester team. Ten students (seven in aerospace engineering and three in mechanical engineering, as part of the KU EcoHawks) participated in the spring semester.

Second Lt. Julian McCafferty, a U.S. Air Force Reserve Officer Training Corps graduate, is the 2014 recipient of the Chancellor John Fra-

ser Distinguished Military Graduate Award in recognition of outstanding achievement as an ROTC cadet. McCafferty was selected for the Fraser Award from a pool of nearly 250 ca-dets and midshipmen in KU’s Army, Navy and Air Force ROTC programs.

Chancellor Bernadette Gray-Little pre-sented the award, given by the KU Veteran’s Alumni Chapter, at KU’s Joint ROTC Commissioning Ceremo-ny held May 19 in the Kansas Union Ballroom. The recipient of the award exemplifies academic excellence, lead-ership, physical fitness and dedication to community service.

While a cadet, McCafferty took on numerous leadership positions in his detachment, including serving as cadet wing vice commander, and he man-aged many core training and develop-ment functions of the AFROTC pro-gram. As a student, McCafferty pub-lished two peer-reviewed academic papers on aerospace-related subjects and held both the vice president and president positions in the Sigma Gam-ma Tau National Aerospace Honor Society. In addition, he was lauded by professors as the Outstanding Aero-space Sophomore and selected for in-ternships at the prestigious Air Force Institute of Technology, the National Reconnaissance Office, and he was peer-selected as class CEO of a 40-plus team successfully competing in the National Wind Turbine build com-petition.

Aerospace Engineering undergraduate junior Ryan Endres was se-lected by Aviation Week magazine as one of the winners of To-morrow’s Engineering

Leaders: The Twenty20s. Department chair, Z.J. Wang nominated Endres.

“Ryan is a great representative of our students in KU aerospace engineer-ing.” Wang said. “He is not only a straight-A student but also extremely active outside the classroom to make the world a better place. I am very im-pressed with his can-do attitude.” En-dres is the President of Engineers Without Borders, a Self Engineering Leadership Fellow, and involved with Student Senate.

Endres credited a well-rounded educa-tional experience at KU for helping him earn the recognition in Aviation Week. “I think it’s critical to be engaged and participate in activities you have pas-sion for. Don’t use time as an excuse. The perfect time to get involved is now,” Endres said.

University of Kansas graduate pro-grams posted big gains in the 2015 edition of U.S. News & World Re-port’s “Best Graduate Schools.” Ac-cording to US News and World Re-port, KUAE is the highest ranking AE program in the State of Kansas.

“Thanks to all the faculty and graduate students, we worked together and im-proved research expenditure and re-search quality that shows in the im-

proved ranking.” said department Graduate Director, Charlie Zheng. The department ranking improved 8 spots to No. 27 among public universi-ties and No. 39 overall.

Early March, five students from the University of Kansas Aerospace Engi-neering Department traveled to Wash-ington D.C. to meet with Kansas's six government representatives.

Introduction Most birds migrate in extraordinarily organized groups. The well-held belief is that traveling with certain formations give an

energetic benefit for those birds that are flying behind. The aerodynamics and sensory feedback involved in such flight dynamics is

so complicated that fully comprehension were previously not investigated thoroughly. By employing Computational Fluid Dynam-

ics, we studied some interesting phenomena about detection of vortex trajectories and energy harvesting of bio-inspired flapping

airfoils. The knowledge gained in this study can be used substantially enhance the energy efficiency of Micro Air Vehicles

(MAVs), which usually need to cover sufficiently long distances on their own power supplies.

Vortex Trajectory

One would expect that a symmetric wake would form downstream of a

symmetric airfoil with a symmetric sinusoidal motion. However, asymmetric

wakes are observed occasionally.

The asymmetric wake only emerges under certain circumstances, such as

high Reynolds numbers and moderately high flapping frequencies/amplitudes.

The vortex dipole model developed in our study leads to an

in-depth understanding of the mechanisms of how such asymmet-

ric wakes form downstream of asymmetric flapping airfoil.

Conclusions drawn from this study can greatly help detect

irregular vortex trajectories downstream of flapping airfoils.

Energy Harvesting

Vortical wakes generated by preceding birds in the traveling group possibly store abundant amount of energy. It raises an

interesting question on how the following birds fly at “sweet spot “ to harvest such energy.

The interaction modes of leading edge vor-

tex (LEV) and trailing edge vortex (TEV) of the

flapping airfoil play a significant role on produc-

ing propulsive energy when it is placed inside a

vortical wake.

Conclusions extracted from this study can

provide valuable flight dynamics patterns to

achieve optimal energy efficiency.

Dr. Huixuan Wu’s research interest include the applied optics, non-equilibrium thermodynamics, and nonlinear dynamics. His PhD research focused on the complex flow of turbomachinery, which is crucial to power generation. His research group constructed a transparent propeller mode, whose optical index was matched to that of the working fluid. He performed particle imaging velocimetry(PIV) measure-ments and characterized the three-dimensional turbulent field in the tip region of the rotating rotor blade. This work elucidated the gerneation mechanisms and the evolution processes of the tip leakage flow, which can induce noise, efficient loss, vibration, and even structure failures.

Particle image velocimetry, as indicated by this name, is a family of velocity measurement techniques using particles and imaging. However, modern PIV is not limited to the velocity probing. It includes, for example, temperature sensing and particle tracking. Dr. Wu’s objective is to combine holographic PIV and Lagrangian particle tracking to study con-vection, thermophoresis, and sedimentation.

Aerodynamics and fluid machinery flow play a vital role in the modern human life, especially in the aspects of trans-portation and power generation. Dr. Wu utilizes PIV to measure the complex fluid motion in a rotor passage. This is criti-cal to improve the engine operation stability, which is closely related to the tip flow, and to understand the efficiency loss, noise generation, flow-structure interaction, as well as the cavitation in hydraulics machines.

Velocity-vorticity probing is a state-of-the-art measurement technology. Currently, Dr. Wu and coworkers are devel-oping a new paradigm of simultaneous velocity and vorticity measurement and will use it to study high Reynolds num-ber turbulence, which is characterized by chaotic vortical motion. The innovative technique detects flow velocity and vorticity by directly measuring translations and rotations of micro-sized particles, instead of deducing vorticity from ve-locities measured at neighboring points. Only this approach provides high enough spatial resolution to investigate the intensive vortex filaments in turbulent flows. The special particles are the key to this measurement. They are transparent and neutrally buoyant hydrogel particles of spherical shape and with encapsulated micro-mirrors.

Dr. Wu studied complex vortical flows at Johns Hopkins University from 2005 to 2011. After that, he began to work at Max Planck Institute in Germany. He earned the Alexander von Humboldt Scholarship, which supported his research of simultaneous velocity and vorticity measurements in complex flows. Dr. Wu uses and develops particle-based flow diag-nostic techniques, including particle image velocimetry (PIV), laser Doppler velocimetry (LDV), and optical vorticity probing, to study fluid machinery flows, turbulence, and flow-structure interactions.

Member of KU’s first Aeronautical Engineering graduating class of 1944, Joe Gray visited the department this May for the 70th Reunion. After graduating from KU Gray reported to Langley Field, VA to begin work at the NASA 8’ x 20’ atmospheric wind tunnels. After being sent to Navy Boot Camp, Gray was ordered to report for duty at the Annapolis Engineering Experimentation Station where he was assigned to work on jet propulsion devices under the BuAer ted ees3401 project. While there he worked on the development of liquid rockets and air breathing pulse jets. In less than a year the Navy moved our group to Mojave, California where he consolidated with the aerodynamics and airframe group of Willow Grove, PA, the tactical testing and evaluations group of Travis City, Michigan, and the Guidance & Controls group of Wash D.C. to form the Navy’s first

Guided Missile Development Center. For about 1½ years Gray continued pursuing design & development of both rocket & pulse jet motors.

After being discharged from the Navy, Gray started working for the Glenn L. Martin Company at Middle River, Maryland. There he was assigned to work a high altitude sounding rocket. Eventually Gray accepted a new position with Army Ordnance Department at the Pentagon where he served as an advisor to Colonel H.N. Toftoy on powerplants for guided missiles. In 1952 Gray left the Pentagon and started working with his father and co-founded Gray Manufacturing Co., Inc. in St. Joseph, Missouri.

Today Gray Manufacturing is America's leading manufacturer of lifting and positioning devices used in the service and repair of heavy over-the-road trucks and buses. Sister company, Vektek, Inc. is America’s largest manufacturer of prismatic power work-holding devices which are primarily used on fixtures to hold work pieces in place during machining. Besides still being active in his two companies, Gray enjoys reading and collecting art. His wife of 66 years, Anne recently passed away. They have 8 children who all survive.

Scientists studying the behavior of the world's ice sheets--and the fu-ture implications of ice sheet behavior for global sea-level rise--may soon have a new airborne tool that will allow radar measurements that previously would have been prohibitively expensive or difficult to car-ry out with manned aircraft.

In a paper published in the March/ April edition of IEEE Geoscience and Remote Sensing Magazine, researchers at the Center for Remote Sensing of Ice Sheets (CReSIS) at the University of Kansas noted that they have successfully tested the use of a compact radar system inte-grated on a small, lightweight Unmanned Aircraft System (UAS) to look through the ice and map the topography underlying rapidly mov-ing glaciers.

"We're excited by the performance we saw from our radar and UAS during the field campaign. The results of this effort are significant, in that the miniaturized radar integrated into a UAS promises to make this technology more broadly accessible to the research community," said Rick Hale, professor of aerospace engineering and associate direc-tor of technology for CReSIS.

With support from the National Science Foundation's Division of Polar Programs and the State of Kansas, the CReSIS team recently success-fully tested the UAS at a field camp in West Antarctica.

The measurements were the first-ever successful sounding of glacial ice with a UAS-based radar. If further tests in the Arctic prove as successful, the UAS could eventually be routinely deployed to measure rapidly changing areas of the Greenland and Antarctic ice sheets.

This advantage is of great benefit, the researchers point out, "in remote locations, such as Antarctica, [where] the cost associated with transporting and caching fuel is very high."

The vast polar ice sheets hold an enormous amount of the Earth's freshwater--so much so that in the unlikely event of a sudden melt, global sea level would rise on the order of 66 meters (216 feet).

The use of unmanned aircraft in Antarctica, which is becoming a subject of wide international interest, is scheduled to be discussed in May at the upcoming Antarctic Treaty Consultative Meeting in Brazil.

The small but agile UAS has a takeoff weight of about 38.5 kilograms (85 pounds) and a range of approximately 100 kilometers (62 miles). The compact radar system weighs only two kilograms, and the antenna is structurally integrated into the wing of the aircraft.

The radar-equipped UAS appears to be an ideal tool for reaching areas that otherwise would be exceptionally difficult to map. The light weight and small size of the vehicle and sensor enable them to be readily transported to remote field lo-cations, and the airborne maneuverability enables the tight flight patterns required for fine scale imaging. The UAS can be used to collect data over flight tracks about five meters apart to allow for more thorough coverage of a given area.

According to Shawn Keshmiri, an associate professor of aerospace engineering, "a small UAS also uses several orders of magnitude less fuel per hour than the traditional manned aircraft used today for ice sounding."

The vast polar ice sheets hold an enormous amount of the Earth's freshwater--so much so that in the unlikely event of a sudden melt, global sea level would rise on the order of 66 meters (216 feet).

Even a fraction of the melt, and the associated sea-level, rise would cause severe problems to people living in more tem-perate areas of the globe, so scientists and engineers are seeking quicker, less expensive ways to measure and eventually predict exactly what it is that the ice sheets are doing and how their behavior may change in the future.

Until now, the lack of fine-resolution information about the topography underlying fast-flowing glaciers, which contain huge amounts of freshwater and which govern the flow of the interior ice, makes it difficult to model their behavior ac-curately.

"There is therefore an urgent need to measure the ice thickness of fast-flowing glaciers with fine resolution to determine bed topography and basal conditions," the researchers write. "This information will, in turn, be used to improve ice-sheet models and generate accurate estimates of sea level rise in a warming climate. Without proper representation of these fast-flowing glaciers, advancements in ice-sheet modeling will remain elusive."

With the successful test completed in the Antarctic, the researchers will begin analyzing the data collected during this field season, miniaturizing the radar further and reducing its weight to 1.5 kilograms (3.3 pounds) or less, and increasing the UAS radar transmitting power.

In the coming months, they will also perform additional test flights in Kansas to further evaluate the avionics and flight-control systems, as well as optimize the radar and transmitting systems.

In 2015, they plan to deploy the UAS to Greenland to collect data over areas with extremely rough surfaces and fast-flowing glaciers, such as Jakobshavn, which is among the fastest flowing glaciers in the world.
