A Fixed Steady Total Pressure Distortion Generator

Abstract

The invention discloses a fixed steady-state total pressure distortion generator, which comprises a main body bracket, a connecting casing, a gas sealing cover, a distortion net assembly, and a sealing ring, wherein: the main body bracket is circular, and it is connected with the gas sealing cover Connected and plugged into the connecting casing, the inside of the main body bracket is divided into several areas; the connecting casing is circular, located in the circumferential direction of the main body bracket, and a through groove is opened in the circumferential direction of the connecting casing; the gas sealing cover It is connected with the connection casing through a hinge; the distortion net assembly is plugged into one or more areas inside the main body bracket; the sealing ring is arranged between the gas sealing cover and the connection casing, and its upper and lower sides are respectively The gas seal and the connecting receiver fit together. The invention adopts modular and detachable fan-shaped distortion net components, which can be combined to produce circumferential and radial steady-state total pressure distortions with different strengths, distributions and angles. Since the distortion net components are easy to assemble and disassemble, the distortion form can be quickly changed during the test, saving workload.

Description

Technical field [0001] The present invention belongs to an apparatus that affects gas flow in the air engine or in the inlet conduit of the air engine, and is an impeller mechanical technology. Background technique [0002] The total pressure distortion refers to the unevenness of the total pressure parameters of the impeller mechanical imported flow field. According to the positional relationship between distortion, it can be divided into circumferential distortion, radial distortion, and circumferential and radial combination distortion. The total pressure distortion will produce a variety of hazards, such as making the compaction ratio of the compressor and the efficiency, and the asthma is reduced, threatening flight safety. To carry out this experimental study, there must be an apparatus for simulating the total pressure of the intake air pressure. [0003] In the ground performance test of the compressor, a distortion web can be set in front of the airway, and the steady st...

Problems solved by technology

[0004] 1. To generate a variety of distortion maps, only multiple distortion nets can be produced, which increases the cost of the experiment and greatly increases the time-consuming preparation of the experiment

[0005] 2. If you want to change the distortion form during the test, you need to disassemble and assemble the whole device continuously, which requires a lot of work and time-consuming
