  • Method for monitoring thrust produced by gas turbine engines
    Patent number: 7762125
    Abstract: A method for providing an indication of thrust available from a gas turbine engine, the method comprises measuring fan aerodynamic speed to produce an actual fan aerodynamic speed measurement, determining a difference between the actual fan aerodynamic speed measurement and an expected fan aerodynamic speed measurement, and if the difference is less than a predetermined threshold value, indicating that sufficient thrust is available.
    Type: Grant
    Filed: March 7, 2007
    Date of Patent: July 27, 2010
    Assignee: Rolls-Royce PLC
    Inventors: Matthew I. Howlett, Charmaine H. Cordo, Karen S. Sollars
