Abstract

The invention discloses a jet-vane simple load simulation and testing device for a thrust vector engine, and the device comprises an improved thrust vector engine jet pipe, a steering engine transmission load mechanism and a testing apparatus. The improved thrust vector engine jet pipe is formed in a manner that four groups of first and second rectangular plates which are arranged in central symmetry in the axial direction of the jet pipe are welded at the periphery of an existing thrust vector engine jet pipe. An electric steering engine in the steering engine transmission load mechanism drives a vane to deflect through a vane connecting rod, so as to simulate the gas load of an actual jet vane through the generated spring torque. The testing apparatus comprises a U-shaped supporting plate, a shaft coupler and a torque sensor, wherein the torque sensor can measure the hinge torque at the vane in real time. The device can effectively reduce the testing cost of the jet vane of the thrust vector engine, is simple and reliable in structure, and is high in testing precision of the dynamic performances.

Description

technical field

[0001] The invention belongs to the field of engine testing, and in particular relates to a simple analog load and testing device for a thrust vectoring engine gas rudder. Background technique

[0002] Most of the mature thrust vectoring engine gas rudder test systems developed in China directly perform performance tests on the gas rudder during the ignition test of the thrust vectoring engine. Since the gas load generated during the ignition test changes with the gas flow rate, the test data Large changes, not accurate enough; ignition test will generate a lot of high temperature, need to carry out thermal protection treatment on the test device or use other transmission mechanism to transmit test torque, thermal protection safety performance is unreliable, easy to cause ablation of the test device, and too much An improved transmission mechanism will lead to an increase in the error of the test data, which is not conducive to the derivation of the test data...
