  1. NASA Dryden Status Aerospace Control & Guidance Sub-committee Boulder, CO February 2007 John Bosworth (661) 276-3792 John.bosworth@nasa.gov

  2. Sierra-Nevada Corp. working more robust algorithms with 2 of 3 successful with 100% miss recognition Took fuel with autonomous disconnect Successfully demonstrated plugging with rendezvous 2 mi dist, 60 deg off centerline Soon will demonstrate refueling in a turn Autonomous probe and drogue airborne refueling F/A-18 configured as autonomous testbed Pallet on tanker, otherwise unmodified Relative GPS/INS navigation Monocular camera tracking system Autonomous Airborne Refueling Demonstration (AARD)

  3. Ikhana Project Update • Flying 3-4 flights per day for pilot training at Grey Butte • Preparing for Western State Fire Mission this summer • Ames • USFS • ARTS III research controller hardware is ready. Software is being developed • Combined aircraft and payload commands • Sensor fusion (IVHM) • Intelligent mission management • GA is developing software to accept “ground station” commands from the on-board ARTS III research controller • Mission plans • Autopilot hold commands • Stick, Rudder and throttle commands

  4. Quiet Spike • Joint program with NASA & Gulfstream AIAA 2005-1015 • Flight Test Completed • No SMI extended or retracted (despite ground test predictions) • Envelope cleared to M 1.8 • Small effects on stability, CAS on • Damping derivatives reduced significantly - Cmq near zero at M 1.8 - Marginally acceptable CAS Off HQ predicted F-15B with Quiet Spike Extended

  5. Sim CAT 43 Sim CAT 51 X X X X Sim CAT 50 X X X X Sim CAT 53 X X X X X Sim CAT 42 Sim CAT 47 F-15 Intelligent Flight Control System • Completed space-based range testing • Completed Quiet Spike probing flights • Returning to IFCS flights in March • Larger canard multipliers • HQ metrics for asymmetries • Working improved direct adaptive neural network Roll due to Pitch Pitch due to Roll Coupling Metric Developed for Rotocraft

  6. F-15 Intelligent Flight Control System • Investigating PIO tendency • Driven by roll-to-pitch weight • Errors due to PIO not large enough to move roll weights • Trade off between dead zone and sensitivity

  7. C-20A Precision Autopilot Development Unmanned Aerial Vehicle Synthetic Aperture Radar (UAVSAR) • Goal: Fly for up to 200 km within a 10 meter tube with light turbulence • Status • Flight Readiness Review Board briefed December 2006 • Formal Software Qualification completed February 2007 • Precision Autopilot Demonstration flight early 2007 Monte Carlo Simulation Results

  8. Low speed taxi tests completed in Dec 2006 Verification and validation of flight software is 75% complete Flight readiness review scheduled for mid Mar 2007 X-48 Blended Wing Body • Potential testbed for future ARMD work

  9. To Fly What Others Imagine …
