abstract

Future propulsion systems will require more complex control systems. More control functions will be necessary to maintain adequate flow stability margin in a propulsion system during all phases of flight and achieve the optimum fuel economy for any desired thrust setting. The representative control requirements of a current and advanced propulsion system are presented to illustrate the need for increasing the sensing and computational capabilities of propulsion controls. If future controls are expected to develop the maximum performance potential from a propulsion system during all flight conditions, then more direct methods for sensing critical engine parameters must be employed which establish the level of component performance and stability rather than prescheduling their operation. In addition, the control functions of the inlet, engine, and exhaust nozzle must be totally integrated by a “propulsion system control” and coupled with the aircraft guidance and control system to insure that optimum aircraft performance is maintained during all modes of flight operation.
