Abstract

The invention discloses a production method of an adsorption type hollow stator blade and belongs to the technical field of engine design. The production method comprises steps as follows: firstly, first air vents are formed in a pressure surface, second air vents are formed in an upper flange plate, and the pressure surface and a suction surface are subjected to sheet metal forming respectively; then the pressure surface and the suction surface are subjected to diffusion welding, a blade body of the stator blade is formed, and a hollow cavity is formed between the pressure surface and the suction surface; finally, the upper flange plate, a lower flange plate and the blade body of the stator blade are welded into the hollow stator blade, and the first air vents and the second air vents are communicated to the hollow cavity. An active control technology for air flow separation can be realized through maturing of an adsorption type hollow stator blade technology, the aerodynamic performance is improved, and the development of adsorption type engines can be accelerated.

Description

technical field [0001] The invention belongs to the technical field of engine design, and in particular relates to a method for manufacturing an adsorption-type hollow stator vane. Background technique [0002] An important development direction of the current aero-engine compressor is to increase the stage pressure ratio of the compressor to achieve a higher pressure ratio than the original number of stages, or to achieve the same total pressure ratio with fewer stages. One of the ways to increase the pressure ratio of compressor stages is to increase the bending angle of the blades, but increasing the aerodynamic bending angle will inevitably be limited by flow separation. In order to control this flow separation, unconventional adsorption compressor design techniques can be used , this technology is to remove the adsorption surface layer at the strong reverse pressure gradient on the suction surface of the blade, so that the airflow can completely adhere to the rear secti...
