Abstract

A control to control the acceleration mode for a gas turbine engine so as to allow the engine to accelerate rapidly with adequate stall margin by simulating a compressor stall limit. The stall limit is attained by generating a limiting ratio of burner pressure and another engine pressure as a function of corrected compressor rotor speed assuming that the stall margin is independent of compressor bleed, power extraction and degradation of engine efficiency.
