Problems solved by technology

In particular, the ejection load is a super large load, and the load direction is at a certain angle with the horizontal direction. If the hydraulic cylinder is used to directly load, it will inevitably increase the complexity of the test support system and increase the difficulty of test loading. There is no precedent in China.
[0003] On the other hand, full-scale landing gear static tests gene...

Embodiment Construction

[0026] The present invention will be further described below in conjunction with accompanying drawing.

[0027] The overall installation diagram of the static test is as follows: figure 1 As shown, it includes a planar test bench 1, an undercarriage 2, and a side load loading device, a heading load loading device, a vertical load loading device, an ejection load loading device, and a pinning load loading device for loading loads through a loading actuator 3. device and tethered load loading device. For the static loading test of the nose landing gear of the catapult take-off carrier aircraft, the landing gear 2 needs to be installed upside down on the test bench 1, and the landing gear and the test bench are connected by the supporting fixture 5 and the loading fixture 4.

Abstract

The invention provides a plane type ejection launch carrier-borne aircraft front undercarriage static force test loading apparatus. The apparatus comprises a plane type test bench rack, an undercarriage, a lateral load loading device, a course load loading device, a vertical load loading device, an ejection load loading device, a hamper load loading device and a mooring load loading device. Based on a conventional loading technology, a set of loading equipment capable of applying ejecting, hampering and mooring loads is designed, and the vertical, course, lateral, ejection, hampering and mooring load loading of an ejection launch carrier-borne aircraft is finished on a single test bench, no replacement of tools is needed, all the loading points are fixed in the frame type test bench, a self-balance bearing system is formed when loading is performed, the bearing of the test bench is quite small, the fixation is facilitated, and the precision is high.

Description

technical field [0001] The invention relates to the field of aviation equipment detection, in particular to a static force test loading device for the front landing gear of a plane type catapult take-off carrier aircraft. Background technique [0002] The static test of full-scale aircraft landing gear mainly tests the structural performance of the landing gear and assesses the bearing capacity of the landing gear. During the test, it is necessary to apply loads in all directions according to the loading conditions of the landing gear to simulate its real loading conditions. At present, for the static test of the traditional aircraft nose landing gear, it is generally used to invert the landing gear, design a dummy wheel, and transfer the load on the actuator to the landing gear through the connection of the dummy wheel. During the transfer process, it is required not to change The size and direction of the load are used to simulate the vertical, directional, and latera...
