Differential Horizontal Tail Effectiveness Analysis And Applied Research

This article discusses the differential tail design, which will be proved to improve the roll ability for the aircraft and it will be possible for reconfiguration of the flight control processing in the design when the aircraft has a wrong.Firstly, a dynamics equation is got by analyzing the aerodynamics change brought by aircraft differential tail. Then the parameter change of the aircraft state equation will be studied by it.Secondly, the article studies the stability, control performance and reconfiguration ability of the aircraft in theory when the differential tail is used.Finally, the flight control performance is discussed by the aircraft lateral equation of motion when the differential tail works.
