Abstract:
PROBLEM TO BE SOLVED: To provide an unmanned air vehicle capable of performing vertical takeoff from and landing on inclined surfaces. SOLUTION: Takeoff and landing modes are added to a flight control system of a Vertical Take-Off and Landing (VTOL) Unmanned Air Vehicle (UAV). The takeoff and landing modes use data available to the flight control system and the VTOL UAV's existing control surfaces and throttle control. As a result, the VTOL UAV can takeoff from and land on inclined surfaces without the use of landing gear mechanisms designed to level the UAV on the inclined surfaces. COPYRIGHT: (C)2009,JPO&INPIT
