Flight Test of Upset Recovery System for SUAS

The initial flight tests of the RAIDER upset recovery system being developed under a NASA Phase II effort were conducted in October. The team flew the first of a planned fleet of 3 Ultrastick 120 research vehicles.  A high fidelity simulation for these vehicles was previously developed by NASA Langley and UMN, providing a rare combination of matching high-fidelity simulation and low-cost test aircraft.  The tests demonstrated the capability to autocode control laws in Simulink, compile them for the Pixhawk autopilot, and execute them in flight through a custom flight mode.  Tests culminated with a successful demonstration of the RAIDER system for an example upset scenario.
