The analysis of data obtained from sweep-frequency testing of the 585 turbojet combustor is discussed.Bode plots of the response of combustor pressure to sinusoidal disturbances in fuelspray- nozzle pressure are presented for a range of fuel flows. An analog simulation was developed and used to match the experimental data and to identify the combustion dynamics. The effects of primary or burning-zone fuel-to-air ratio on the system response were also investigated. The experimental data were fit by linear transfer function forms to be used in overall system studies.

A cross-coupled inlet-engine control system concept is presented for a supersonic propulsion system consisting of a mixed- compression inlet and a turbojet engine. The control system employs manipulation of both bypass door flow area and engine speed to stabilize normal shock position in the inlet. Specifically, the case of slow-acting bypass doors used as a reset control where engine speed is the primary means of shock position control is described. Experimental results are presented showing performance of the control system with a NASA-designed inlet and a turbojet engine operating at Mach 2.5 in the Lewis 10- by 10-Foot Supersonic Wind Tunnel.
