Identification of Saras flight stability and control characteristics
暂无分享,去创建一个
Longitudinal stability and control characteristics and the neutral point of Saras aircraft are estimated from flight test data by applying classical and parameter identification techniques. The accuracy of the nose boom and the side-mounted angle-of-attack vanes is assessed using steady-state level flight data. The angle-of-attack accuracy is also assessed by applying flight path reconstruction techniques to flight data from short period pitch stick maneuvers. Results from the classical and parameter identification techniques are compared with the design data from wind tunnel tests.
