Calspan Status Update

AG&C Committee, October 11-13, 2006

Williamsburg, VA

Lou Knotts/Eric Ohmit


Calspan status update1

Calspan Status Update

  • Lear AAR Flight testing at Niagara Falls

  • Learjet Sense & Avoid Project

  • VISTA Status

  • OIW Sea Scout Instrumentation


Learjet aar

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

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


Learjet sense avoid flight test

  • 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 test1

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

Vista

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

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)
