Abstract

The invention belongs to the technical field of aero-engine tests. The invention relates to a rectangular combustion chamber air inlet rectifying device. The device is used for inlet air rectificationof a rectangular combustion chamber. The air inlet rectifying device comprises an upper rectifying wall surface (1), a lower rectifying wall surface (2), a left rectifying wall surface (3) and a right rectifying wall surface (4), wherein the upper rectifying wall surface, the lower rectifying wall surface, the left rectifying wall surface and the right rectifying wall surface enclose a structurewith a channel and a rectangular outer section, the front end of the channel is connected with an air inlet section of a test device, the rear end of the channel is connected with the rectangular combustion chamber, and an arc-shaped convergence channel is arranged at the part, close to the air inlet section, of the inner wall of the channel to form a rectification surface. Aiming at the problem that the air inlet uniformity of a combustion chamber is greatly influenced by the shape of the pipeline of the test device due to the fact that a conventional rectangular combustion chamber casing isprovided with uniform-section channels from front to back, the rectifying device is designed, the rectifying effect on inlet air is achieved through a rectifying molded surface, and the accuracy of atest result can be effectively ensured.

Description

technical field [0001] The application belongs to the technical field of aero-engine testing, and in particular relates to a rectifying device for air intake in a rectangular combustion chamber. Background technique [0002] The combustion chamber is an important part of the gas turbine, located between the compressor and the turbine. Its structure is various, but basically it is composed of basic components such as diffuser, casing, flame tube, fuel nozzle and ignition device. Its main function is to mix and burn the high-pressure air supplied to the main combustion chamber with fuel, convert the chemical energy of the fuel into thermal energy, form high-temperature and high-pressure gas, enter the turbine and nozzle, expand and do work, and generate engine thrust. Since the combustion chamber involves complex physical and chemical processes such as aerodynamics, combustion, chemical reactions, and two-phase flow, a large number of experimental studies are required in the ...
