ABSTRACT:
A thrust augmented twin spool turbofan engine system to control instability at high altitude, low Mach number conditions wherein an engine electronic control monitors engine inlet temperature, engine burner pressure and Mach number, and inhibits fuel flow to the outermost augmentor segment when the engine inlet temp drops below 25.degree. F, when engine burner pressure drops below 120 psia or when the Mach number drops below 0.4. When fuel flow to the outermost augmentor is inhibited, upmatch logic modifies the variable nozzle AJ trim signal closed 8% and the power level angle trim signal up 4.degree..
