Miniature gas turbine engine stator part integrated device

Abstract

The invention discloses a miniature gas turbine engine stator part integrated device which comprises a gas compressor impeller, a bearing chamber and a combustion chamber are arranged in the gas compressor impeller, a fuel oil pipe is installed between the bearing chamber and the combustion chamber, and the fuel oil pipe is communicated with the combustion chamber; the bearing chamber comprises a front bearing and a rear bearing, the front bearing and the rear bearing are located at the two ends of the bearing chamber respectively, and a front bearing accessory is arranged on the side wall of the front bearing. And one end of the compressor impeller is fixedly connected with a shaft end nut. An additive manufacturing forming mode is adopted for the stator part of the micro-miniature gas turbine engine, an integrated structural design is adopted for the stator part of the micro-miniature gas turbine engine, a diffuser, a fuel oil pipe, a bearing chamber, a combustion chamber and other parts of the engine are integrally designed, the assembly process of the stator part of the engine is greatly simplified, the assembly time of the engine is shortened, and the assembly efficiency is improved. The connection reliability of the engine is improved; and meanwhile, the use of connecting mechanisms among the parts is reduced, and the position tolerance of the stator part can be better realized.

Description

technical field [0001] The invention belongs to the technical field of engine stator parts, and in particular relates to an integrated device for a micro-miniature gas turbine engine stator part. Background technique [0002] A gas turbine engine, or a gas turbine, is a type of engine that belongs to a heat engine. Gas turbine engines generally refer to those used in ships, vehicles, generator sets, etc. The difference from the turbine engine for propulsion is that the turbine not only drives the compressor, but also drives the transmission shaft, which is then connected to the transmission system of the vehicle, the propeller of the ship or the generator. [0003] The stator parts of traditional miniature gas turbine engines are generally composed of diffusers, fuel oil passages, bearing chambers, combustion chambers, guides and other components, as well as the connecting mechanisms between them. There are many processes in the process of engine assembly, and the assembly...
