The feasibility of using active aerodynamic surfaces to improve the vertical ride quality of a tracked air cushion vehicle is investigated analytically with a six-degree-of-freedom linear model. Two aerodynamic fins actively control the pitch and plunge steady-state acceleration response of the passenger compartment to harmonic guideway excitations. For speeds of 200 to 300 mph, the choice of simple acceleration feedback signals sensed at the passenger compartment c.g. results in an acceptable ride quality. This is attained by practicable angles of attack and reasonable torques for the aerodynamic surfaces. (Author)
