Summary

The effects of diffuser dynamics (for supercritical diffuser operation) and controlled engine dynamics on the diffuser control requirements of a supersonic turbojet engine were studied with the aid of an electronic analog. The investigation indicated that a pressure disturbance in the diffuser had only a small effect on engine speed, whereas a disturbance in engine speed had a large effect on diffuser pressure and could impose severe requirements on diffuser control response.
