Study of Deep-Stall Characteristicsof T-Tailed Aircraft

Abstract The deep-stall opened loop characteristics of T -tailed aircraft are discussed by the time histories method. The effects of aerodynamic moment characteristics and elevator control law on the deep-stall characteristics are analysed. The mathematical model of the deep-stall closed loop characteristics are presented. The effect of pilot mathematical model parameters on the deep-stall characteristics is analysed. The results show that the effects of aerodynamic moment characteristics, elevator control law, and pilot mathematical model parameters on the deep-stall characteristics are considerable.
