  • Aircraft tow point
    Patent number: 11192661
    Abstract: An aircraft is presented. The aircraft comprises a tow point positioned on a body of the aircraft and forward of main landing gear of the aircraft, wherein the tow point is connected to an airframe of the aircraft to accept and distribute forces forward, aft, and normal to the aircraft.
    Type: Grant

    Date of Patent: December 7, 2021
    Assignee: The Boeing Company
    Inventor: Daniel B. Douglass
  • Methods and apparatus for controlling landing gear retract braking
    Patent number: 10933982
    Abstract: Methods and apparatus for controlling landing gear retract braking are described. A controller determines wheel speed data corresponding to a speed of a wheel of a landing gear. The controller determines wheel deceleration data corresponding to a rate of change of the wheel speed data. The controller generates a first control signal in response to the wheel deceleration data being greater than a wheel deceleration threshold. The first control signal initiates a wheel deceleration regulation process, the wheel deceleration regulation process to cycle an antiskid valve between a first valve position to release brake pressure from the wheel and a second valve position to cease releasing the brake pressure from the wheel. The controller generates a second control signal in response to the wheel speed data being less than a wheel speed threshold. The second control signal terminates the wheel deceleration regulation process.
