Abstract
An airframe power unit for producing a power output in accordance with the invention includes a combustor (16) having a fuel injector (58) which injects fuel into the combustor which is combusted to form a gas stream (18); a turbine (12) driven by the gas stream from the combustor for producing the power output; an air supply (20) for providing pressurized gas containing oxygen blown down from a storage vessel (22) to the combustor which is used in the combusting of the fuel; a valve (24) disposed in the gas supply which controls a rate of supply of gas to the combustor in response to the control signal applied to the valve to cause the turbine to operate with a constant operational characteristic; a control for providing at least one control value (P.sub.S and S.sub.S) with each value specifying a desired operational parameter for use in producing the constant operational characteristic; a sensor (31 or 68) for sensing at least one operational parameter of the turbine; a difference circuit (32, 204, 404 or 504 ) for producing the control signal as a function of a difference of at least one control value and a corresponding sensed operational parameter; and a fuel control (50) for controlling the rate of injection of fuel by the fuel injector into the combustor.
