Calspan Status Update
• Lear AAR Flight testing at Niagara Falls • Learjet Sense & Avoid Project• VISTA Status• OIW Sea Scout Instrumentation
Learjet AAR
• Third Flight Test:– Jul/Aug 2006
– At Niagara Falls with 107th ANG KC-135
• Very efficient operations
• Dedicated aircraft / crews / facilities
– AUTONOMOUS Station-Keeping
– Safety Pilot flew to various refueling positions, then engaged simulation
– AAR GPS-based Control Laws in Boeing Flight Control Computer - FCC
– FCC interfaced with Learjet VSS through sensors & commands to control elevator, aileron, rudder, throttle.
• Held relative Tanker-to-LJ engaged positions - VERY precise
• Straight & Level, 30º Banked Turns, & Racetrack patterns
• Light to Moderate Turbulence
– Gathered IR Camera data for “Hybrid” system
– Flew 20 Flights, 30 Flt-Hrs

Learjet AAR
• Fourth Flight Test:
– Jul/Aug 2007
– Similar to 2006 tests, but in addition:
• Autonomous Trajectory Control
• Move from:– Observation Pre-Contact Contact
Breakaway positions.
– Gather more IR data for Hybrid system
In planning phase …
Learjet Sense & Avoid Flight Test
• UAV Sense & Avoid in National Air Space.
• Autonomously Detect and Avoid intruder aircraft
in terminal environment.
• Cooperative & Non-Cooperative Intruders
• Equivalent Level-of-Safety as piloted operations.
• Equivalent Level-of-Behavior as piloted operations.
COOPERATIVE• TCAS or Mode-C• Detectable• Coordinated
Collision Avoidance
NON-COOPERATIVE• Detect with Cameras
Learjet Sense & Avoid Flight Test
• AFRL – Sponsor• Northrop Grumman (NGC) – Prime contractor• Calspan – Installations and Flight Test in Learjet
– Simulate UAV (Global Hawk-like) dynamics• Defense Research Associates (DRA) – Camera system, detector, tracker• Bihrle – Provides avoidance software• FAA – Provides “Intruders”
– Convair-580 and King Air• Cooperative Intruder (TCAS-II Equipped)
– Utilizes Resolution Advisory (RA) commands• Non-Cooperative Intruder (No transponders, Uses only cameras)
– DRA supplies 3-Camera system - Detects & Tracks Intruder– NGC/Bihrle software determines trajectories and avoidance maneuvers
• Intrusion Scenarios:– Level head-on, cross-track, climb/descend head-on, overtaking
• Flying starts 23 October, 2nd session in December @ Niagara Falls
Learjet Sense & Avoid Flight Test
Modified LJ Radome with 3-Camera SAA
Installations
VISTA
• Completed 2006 flight test support for AFTPS – Support TPS (Handling Qualities, EO & A-A)
curriculum– TMP projects (BATDART)– AFRL Voice Recognition– Proprietary program
• Supported by Calspan personnel and test pilots on-site at EDW AFB
• Aircraft at Depot Hill AFB for Falcon-up til July ‘07
OIW Sea Scout UAV Instrumentation
• Sea Scout UAV program– Vehicle Developed by Oregon Iron Works (OIW)
– Phase 3 SBIR program for NAVAIR
• Utilized Calspan Developed Mini-Flight Data Recorder System (MFDRS) for instrumentation of the Sea Scout UAV– Support initial developmental testing
– Goal to get initial look at PID and engine characteristics prior to autonomous flight testing
• MFDRS is a small, self contained data recording system– Data stored on CompactFlash card, data reduction directly in
Matlab/Simulink
– Control surface positions (string pots, el, er, r, al, ar)
– Aircraft responses (p, q, r, Nx, Ny, Nz, Airspeed, Altitude, AOA, AOS)
– Engine parameters (Temps, diff. pressures, rpm, thrust)
– GPS parameters (lat, long, gnd spd, track, etc)
