TL;DR: In this article, a landing-gear-drop-test driving rotating device is presented, which is mainly composed of a friction wheel, a motor, lifting threaded rods, supports, guiding rails, an actuator cylinder, an adjusting air valve, and a motor rotating speed controller.
Abstract: The invention discloses a novel landing-gear-drop-test driving rotating device and a test method, belongs to the technical field of aeronautical engineering, and relates to a driving rotating mechanism in a landing-gear drop test. The novel landing-gear-drop-test driving rotating device is mainly composed of a friction wheel, a motor, lifting threaded rods, supports, guiding rails, an actuator cylinder, an adjusting air valve, a motor rotating speed controller and the like. The device is used for providing the pre-rotating speed for airplane wheels in the landing-gear drop test; according to the actual requirement, the motor and the type of a driving rotating wheel can be replaced, the height of the motor is adjusted, the rotating speed of the airplane wheels is controlled, and the test shows that the novel landing-gear-drop-test driving rotating device is stable and reliable.
