Abstract
The air-breathing supersonic missile has the characteristics of strong nonlinearity, strong coupling, fast time degeneration, and strong uncertainty. With the increasing requirements for missile speed and accuracy, the elasticity and actuator fault of air-breathing supersonic missiles have become a problem that cannot be ignored. In this paper, the longitudinal dynamics model of the elastic air-breathing supersonic missile is established, the influence of the elasticity of the air-breathing supersonic missile on the attitude is analyzed considering the real-time change of fuel mass, and finally, the comprehensive influence of the elasticity of the air-breathing supersonic missile and the actuator failure on the dynamic characteristics of the missile is analyzed, and the research results can provide reference for related research in this field.
