Abstract :
The ramjet is a new type propulsion system for high-speed flight test aircraft. The ultimate success of sustained high-speed flight will depend on configuring a fine and stable attitude flight control and robust airframe-propulsion-control combination. The mathematical models of high-speed aerodynamic forces and moments were established. A bank-to-turn autopilot structure was used for the longitudinal motion and lateral motion study. The fine attitude controller tracks the commanded angle of attack and normal acceleration.
