Abstract

The invention provides a front undercarriage static force test loading device for a frame-type catapult-assisted take-off shipboard aircraft. The front undercarriage static force test loading device comprises a frame-type test stand, an undercarriage, a lateral load loading device, a course load loading device, a vertical load loading device, an ejection load loading device and a trapping load loading device. The front undercarriage static force test loading device is one of loading technologies in the prior art, the loading device is designed to realize ejection application and load trapping, vertical, course, lateral, ejection and trapping load loadings of the catapult-assisted take-off shipboard aircraft are accomplished on the test stand, tool replacement is not required, all loading points are respectively fixed in the frame-type test stand, a self-balance bearing system is established during loading, bearing force of the test stand is relatively small, and the loading device is convenient to fix and has high precision.

Description

technical field [0001] The invention relates to the field of aviation equipment detection, in particular to a frame-type catapult take-off carrier aircraft nose landing gear static test loading device. Background technique [0002] The full-scale static test of the aircraft nose landing gear is mainly to test the structural performance of the aircraft nose landing gear, and it is necessary to apply loads in all directions to the nose landing gear. For the nose landing gear of a catapult takeoff carrier-based aircraft, the nose landing gear will be subject to vertical, heading, lateral, ejection, pinning and other loads. At present, for the traditional static test loading device of the nose landing gear of the aircraft, the landing gear is generally inverted, the load is transferred through the design of dummy wheels, and the hydraulic actuator is used to directly load the landing gear to simulate the vertical, heading and side load. For the nose landing gear of the car...
