Problems solved by technology

[0005] Low efficiency: The test process on the ground is complicated. The test of engine performance parameters usually requires multiple drives. There are many test personnel, high labor intensity, long test time, serious fuel consumption, low efficiency, and repetition caused by misjudgments and missed tests. Operation also consumes more engine life
[0006] Low degree of automation and informatization: The equipment does not have a special computer to record and save the test data, the parameter records are not timely, the subsequent supplements are not accurate, there is no data traceability function, and there is a lack of automatic management and analysis of the testing process, and the dynamic testing methods are backward

Abstract

The invention provides a piston type aero-engine test stand. The piston type aero-engine test stand comprises an engine installing rack, a testing engine installed on the engine installing rack and a propeller connected with the testing engine; a supporting rod is arranged on the engine installing rack and provided with a lifting device, the terrain clearance of the testing engine can be adjusted, the installing rack is connected with a test stand body, and the test stand body comprises a testing system, an engine testing room and a truck for placing the engine testing room. The truck is used as a chassis, and therefore the test stand is high in mobility, and convenient to transport and move; the lifting device is arranged on the supporting rod and can adjust the terrain clearance of the testing engine, and testing requirements of all kinds of piston type aero-engines can be met conveniently.

Description

technical field [0001] The invention relates to the field of aero-engine testing, in particular to a piston-type aero-engine test bench. Background technique [0002] Aeroengine is a thermal power device with high technical difficulty, complex working conditions, strict maintenance requirements, and high development and use costs. It has a very complex structure and plays a vital role in the reliability, safety and performance of aircraft operation. During the service life of an aero-engine, in order to ensure flight safety, the aircraft engine must be regularly tested according to regulations to detect the performance of the engine. Whether its maintenance quality and technical indicators meet the requirements will directly affect the completion of flight training tasks and flight safety. If the engine fails, it will be extremely harmful, and even lead to major flight accidents in severe cases. Therefore, strengthening the detection of the performance parameters of the en...
