Unmanned aerial vehicle(UAV) in low-speed flight will be affected by wind field at mid-high altitude and complete flight data is difficult to achieve because of the insufficiency of flight test condition.In order to solve these problems,an approach for the method of aerodynamic parameter identification is given.This paper presents a wind field estimation method based on vector triangle plane pitot tube and a pneumatic angle estimation method based on modified wind field information.Taking a fixed wing UAV a...
