Mechanism of high pressure compressor test piece

Abstract

The invention provides a high-pressure compressor test piece mechanism for simulating the working environment of a turbofan engine, which includes a high-pressure compressor body, and an inlet support plate and a transition section flow channel are arranged at the inlet of the high-pressure compressor body , a distortion device is provided upstream of the inlet support plate and the flow channel of the transition section, and the distortion device is located in the outer flow channel of the inlet support plate and the flow channel of the transition section. The invention provides a test structure form of a high-pressure compressor capable of accurately simulating a complete machine environment, including an inlet distortion device, a high-pressure compressor body, and an outlet simulation combustion chamber. At the same time, a set of structural schemes for the inlet distortion device of the high-pressure compressor is provided, which can generate an inlet pressure profile, which is consistent with the inlet pressure profile of the high-pressure compressor in the environment of the whole machine.

Description

Technical field [0001] The present invention relates to the field of a high pressure compressor test member of the turntable engine, and more particularly to a high-voltage compressor test member. Background technique [0002] figure 1 Schematic structural diagram of a typical turntile engine in the prior art. [0003] Such as figure 1 As shown in the prior art, a typical civilian vortex aviation engine is typically a hypervisor. When the machine is experimental, the air flows from the aircraft into the engine. First, the fan 10 enters the engine body, and the flow over-flow ring is divided into two parts, and a portion is discharged through the row of the engine, and a part flows into high pressure. The compressor. Wherein, the branch outlet position 30 belongs to the interface of the high and low compressor. After the air flow is compressed by the high pressure compressor body 40, the gas flow is formed to form a high-temperature high pressure gas, and the core machine is di...
