  • Method and apparatus for the engine control of output shaft speed
    Patent number: 6748744
    Abstract: In accordance with one aspect of the present invention, in a control system for controlling a gas turbine engine, there is provided a system and a method for determining an optimized output shaft speed for a required thrust and setting an appropriate engine power. The method comprises the steps of: providing a required thrust value at a particular flight condition; determining input values for each of a power, output shaft speed, airspeed, and altitude; determining whether the required thrust is a low power condition; if the required thrust is a low power condition, determining a reduced propeller speed value from the input values and the required thrust value; at least one of increasing and decreasing the optimized output shaft speed using the reduced propeller speed value.
