Brian, Chris, Danny, Parul and Raghu arrived at the UMore Park Airfield around 9:00 am on Friday Jan 30th, 2015 for the sixteenth flight of Fenrir. Fenrir flight 16 was to test a new flight control law with just the pitch-damper (pitch_gain = -0.2). The purpose of Fenerir flight 16 was to put excitations on elevator and aileron to gather response data in order to perform system identification and parameter estimation to support the Performance Adaptive Aeroelastic Wing (PAAW, www.paaw.net) program in designing and flight testing the mAEWing1 vehicle. The control surfaces for this flight were also allocated differently from previous flights by allocating outboard surfaces as elevons.
The flight plan was for the pilot to fly the aircraft straight and level (with the pitch-damper running), and to see the aircraft response for 3-2-1-1 excitations of increasing frequencies on the elevator and aileron. Takeoff was followed by a straight line run down a short section of our runway. Unfortunately, the aircraft's battery failed so the flight was cut short. Future flights will include a runup to full throttle to test the batteries.
