Abstract

The invention discloses an integrated micro-miniature gas turbine engine combustion chamber unit body which comprises two symmetrically-installed combustion chamber unit bodies, and a plurality of cooling air holes used for improving the heat insulation capacity and the temperature resistance capacity of a combustion chamber are formed in the combustion chamber unit bodies.

Description

technical field [0001] The invention belongs to the technical field of engine stator parts, and in particular relates to an integrated miniature gas turbine engine combustion chamber unit body. Background technique [0002] Combustion chambers of traditional miniature gas turbine engines are usually combined and welded after spinning. Firstly, high-precision spinning molds of different shapes are designed and processed according to the design drawings of the combustion chambers to ensure the spinning accuracy, and then machined on a flat plate. A series of cooling air holes. After the flat plate is spun, it is finally formed by welding. The manufacturing process of the micro gas turbine engine combustor using traditional technology is relatively complicated and the processing time is long. After forming, the cooling air holes of the combustor are generally perpendicular to the profile. The thermal effect is poor, and the heat capacity strength of the combustion chamber mate...
