Warren R. Larson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Full flight regime autothrottle control system
    Patent number: 4569021
    Abstract: A Mach hold control circuit for an aircraft autothrottle system provides capture of a Mach number and control thereto while providing a low level of throttle activity also stabilizing the aircraft at maximum range cruise (MRC) Mach numbers and above. The Mach hold control law utilizes a Mach error signal, flight path acceleration signal, average engine EPR signal, and associated logic inputs and when interfaced with the autothrottle system provides a throttle rate command to the aircraft engines via. the throttle and engine control system thereby modulating engine thrust to provide control to desired flight Mach number.
    Type: Grant
    Filed: May 23, 1980
    Date of Patent: February 4, 1986
    Assignee: The Boeing Company
