Abstract

A study presented flight-test results of a variable-stability Learjet aircraft augmented with an L1 adaptive flight control law. The flight tests were conducted by the US Air Force (USAF) Test Pilot School (TPS) at Edwards Air Force Base, California, in collaboration with the Calspan Corporation, and mark the first time an L1 adaptive system was implemented and tested on a manned aircraft. The flight-test plan was designed by the team at the USAF TPS and included the assessment of the flying and handling qualities of the L1-augmented Learjet, the determination of the stability margins of the L1 flight control law, offset-to-landing tasks conducted at altitude, and straight-in, touch-and-go landings.
