Static and dynamic mathematical models for a new type of engine and its actual hydraulic control system are proposed. A nonlinear mathematical model is used for the engine and afterburner fuel control system. With programs formed on the basis of these models, the static and dynamic close loop characteristics of this engine control system under afterburning condition have been analyzed in detail. Satisfactory results and valuable conclusions have been obtained. The results are useful for solving many practical problems of the engine control system.
