Abstract: A hydromechanical fuel control for a turboshaft engine includes a gas producer control and an independent power turbine governor in series flow relationship. The basic gas producer control includes an acceleration system, a deceleration system and all speed governor to regulate the fuel flow output of the gas producer control. The acceleration system includes a main metering valve which is positioned by a compressor discharge pressure responsive device and the all speed governor. A speed responsive computer mechanism controls the head across the metering valve. The computer mechanism includes an enrichment valve and a start valve and is connected to the shut-off valve lever for the fuel control in such a manner that the mechanism may be controlled by actuation of this lever. The power turbine governor includes a fuel flow reset governor and a deceleration system to prevent flameouts.
