Fall 1997 Seminar Series



Mission Performance, Guidance, and Control of High-speed Atmospheric Flight Vehicles

Abstract


As the title implies, the seminar will touch on a variety of topics of recent interest. The class of vehicle to be considered includes both supersonic transport aircraft as well as airbreathing launch vehicles. The common theme will be the dynamic subsystem interactions exhibited by these vehicles, and the implications of these interactions vis-à-vis vehicular guidance and control. The interacts to be specifically considered will be termed aeropropulsive/servoelastic (APSE), involving the elastic-airframe, propulsion system, and feedback control systems. The mission performance of airbreathing launch vehicles will be reviewed via a classical energy-state analysis, and a relatively simple energy-guidance law suggested that draws from both energy-state and QFT concepts. The feedback system architecture includes an integrated inner-loop control law that regulates engine performance, stabilizes the airframe, and delivers active aeroelastic mode control.
