AI Technical Summary

Benefits of technology

This new technology allows for easy installation or disassembly of an aircraft's propulsive system without affecting its performance significantly during testing. It also includes measuring forces on both sides of each component separately from one another while maintaining balanced conditions. By analyzing these measurements it provides valuable insights into how well the components work together under various flight regimes.

Problems solved by technology

This patented describes how to evaluate the performance or behavior of certain types of jet systems in smaller gas turbine engines without having them undergo testing at their original manufacturing stage. Current methods require expensive equipment like laboratory tests with specialized tools, making this process difficult if done manually by operators who lack advanced training skills.

Embodiment Construction

[0021] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0022] Such as figure 1 As shown, a vector nozzle test bench for a small turbojet engine includes a fixed support, a six-component balance, a support base, a pillar, and a clamping and fixing assembly.

[0023] The fixed support is used to fix the entire test bench, and the fixed support is fixed on the ground.

[0024] The six-component balance is used to test the inherent thrust characteristics of the engine and the force and moment characteristics of the vector nozzle at different rotation angles. The six-component balance is fixedly installed on the support panel of the fixed support by bolts.

Abstract

The invention provides a small-sized turbojet engine thrust vectoring nozzle testing platform and solves the problem that a common small-sized turbojet engine testing platform cannot test the force and torque features of an engine thrust vectoring nozzle. The small-sized turbojet engine thrust vectoring nozzle testing platform comprises a fixed support, a six-component force balance, a support seat, a clamping and fixing component and the thrust vectoring nozzle and is characterized in that the fixed support is fixedly arranged on the ground, the six-component force balance is arranged on thesupport panel of the fixed support, the support seat is arranged above the six-component force balance, the clamping and fixing component is coordinated with the support seat to clamp and fix a turbojet engine, the thrust vectoring nozzle is arranged along the axial direction of the turbojet engine, the thrust vectoring nozzle is detachably connected with the clamping and fixing component througha connecting rod, and a support column is connected between the support seat and the six-component force balance. By the structure, the small-sized turbojet engine thrust vectoring nozzle testing platform can test the inherent thrust features of the turbojet engine and the force and torque features of the thrust vectoring nozzle under different rotation angles.
