Calspan Status Update AG&C Committee, October 11-13, 2006 Williamsburg, VA Lou Knotts/Eric Ohmit
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 LJ in Contact Position Alternate Radome Modified for IR Camera
Learjet AAR LJ in Contact Position in Turn
Learjet AAR LJ in Observation Position in Turn
Learjet AAR In planning phase … • 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
NON-COOPERATIVE • Detect with Cameras • COOPERATIVE • TCAS or Mode-C • Detectable • Coordinated Collision Avoidance 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.
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, del, der, dr, dal, dar) • 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)
