  1. Calspan Status Update AG&C Committee, March 1-3, 2006 Lake Tahoe, NV E. Ohmit

  2. Calspan Status Update • Lear AAR Tanker testing in Buffalo & TTNT Flight testing • Learjet AFTPS Project (with servo-throttle) • Learjet Sense & Avoid Project • TIFS Boeing Project • TWT – Free to Roll Rig

  3. AAR Sponsored by AFRL Other Major Participating Organizations: DARPA, NAVAIR, Boeing, Northrop Grumman, Rockwell Collins, Titan Utilizing Learjet as “surrogate” UAV Objectives: Clear Learjet to operate up to and including Contact position with KC-135 No actual hook-up Evaluate acceptability of sensors PGPS & Optical, Datalink (TTNT) Evaluate control laws for automated refueling Learjet Automated Aerial Refuleing (AAR) Complete Complete

  4. Learjet AAR • Initial Test Flights (complete) • Sep 2004 • With Niagara Falls ANG KC-135 • Cleared LJ to operate with KC-135 • Gathered data for PGPS & EO sensors • 8 flights, 12.2 Flt-Hrs

  5. Learjet AAR • Second Flight Test (complete): • Datalink tests – Sep 2005 • Tactical Targeting Network Technology (TTNT) • DARPA funded – Rockwell Collins developed • At NAWCWD China Lake, CA • Gathered Datalink (TTNT) data • Simulated Aerial Refueling • Simulated Carrier Approach • Flew with NAVAIR E-2C (Surrogate Tanker) • 5 other aircraft took part: • F-15, F-18, B-707(Paul Revere), T-39, R-C Sabreliner • 3 ground stations • 7 Flights, 9.7 Flt-Hrs, Plus many days of integration and ground tests

  6. Learjet AAR • Third Flight Test: • Autonomous Station-Keeping – Aug 2006. • Re-install PGPS/INS/TTNT. • AAR control Laws in Boeing-supplied Flight Control Computer (FCC). • FCC interfaces with Learjet VSS through sensors & commands to elevator, aileron, rudder, throttle. • Safety Pilot will fly into various refueling positions then engage simulation; AAR Control Laws will Station-keep during typical Tanker maneuvering. • Fly at Niagara Falls with 107th ANG KC-135 • ~20 Flights, 35 Flt-Hrs • Fourth Flight Test: • Trajectory Control – Aug 2007 • As above, but Autonomously move from: • Observation  Pre-Contact  Contact  Breakaway positions.

  7. Learjet AAR - Related Efforts • Servo-Throttle Capability in Learjet • Servo-Throttle installed to achieve 4th DOF. • Electrical servos attached to throttle cables at fuel control lever in each engine. • Installed & Checked out in September 2005. • Utilized in AF Test Pilot School Project with AFIT AAR Control Laws. • Oct 2005, 7 Flights • Installed simple Datalink & GPS • Verified Servo-throttle operations • Autonomously controlled LJ behind a C-12 (King Air) • Trajectory and station-keeping with refueling maneuvers - Held position within 2 ft

  8. Learjet – Future AFTPS Efforts • Flight Controls Project • Performed during every class • Students design and fly simple FCS • Stabilizes an unstable configuration • Test Management Projects being planned for 2007: • AAR-related EO System data gathering • Boundary/PIO evaluations

  9. Learjet Sense & Avoid • UAV Sense & Avoid in National Air Space. • Autonomously Detect and Avoid intruder aircraft in terminal environment. • Equivalent Level-of-Safety as piloted operations. • Based on Global Hawk operations. • Non-Cooperative • Detect with Cameras • Cooperative • TCAS or Mode-C • Detectable • Coordinated Collision Avoidance

  10. Learjet Sense & Avoid • AFRL-Sponsored • Northrop Grumman (NGC) – prime contractor • Defense Research Associate (DRA) - Camera system, detector, tracker • Calspan – Installations and Flight Test in Learjet • Simulate Global Hawk dynamics • Cooperative Intruder Aircraft (TCAS-II or Mode-C Transponder) • Non-Cooperative Aircraft (No transponders, Use Optical Cameras) • DRA supplies 3-Camera system - Detects & Tracks Intruder • NGC software determines trajectories and avoidance maneuvers • Intrusion Scenarios: • Head-on, overtaking, cross-track • Intruder Aircraft: • King Air & KC-135 • Fly 4th Quarter 2006 at Niagara Falls

  11. TIFS Boeing • Proprietary Advanced Control System Flight Tests • June - Dec 2005 • 11 Flights, 18 Hrs • Future efforts planned in 2006

  12. Learjet # 3 Development • 3rd Generation Variable Stability Learjet • Model 25D designed primarily for Upset Recovery Training (URT) • User-friendly Variable Stability System (VSS).

  13. Free To Roll (FTR) Support System • FTR Inaugurated Oct 2005 • Abrupt Wing Stall Studies • Roll damping derivatives • Multi-mode testing • Pitch sweeps • Yaw sweeps • Quick to switch from FTR to S&C test mode
