  • Apparatus and method for controlling landing gear
    Patent number: 10106248
    Abstract: A landing gear system includes landing gear, an uplock that is releasably engageable with the landing gear, an uplock hydraulic actuator operably connected to the uplock, a landing gear hydraulic actuator operatively connected to the landing gear, and a controller operatively connected to the uplock hydraulic actuator and the landing gear hydraulic actuator. In response to receipt of a command to deploy the landing gear, the controller actuates the uplock hydraulic actuator and the landing gear hydraulic actuator to the UP condition and then actuates the uplock hydraulic actuator and the landing gear actuator to the DOWN condition. An alternative embodiment incorporates a piloted check valve upstream of the landing gear hydraulic actuator. The piloted check valve delays operation of the landing gear hydraulic actuator until release of the landing gear by the uplock.
