Abstract

The present disclosure relates to the technical field of aero-engines, and proposes a turbine guide, comprising a turbine casing and an orifice ring guide vane, wherein the orifice plate ring is connected to the outside of the turbine casing; the guide vanes are connected to the inside of the turbine casing; wherein the turbine casing, The orifice ring and the guide vanes are integral parts. The turbine guide of the present disclosure can effectively reduce the number of parts of the turbine guide by arranging the turbine casing, the orifice ring and the guide vanes as an integral structure, with a simple structure and high reliability, thereby solving the problem of the turbine guide in the prior art. The structure of the device is more complex.

Description

technical field [0001] The present disclosure relates to the technical field of aero-engines, and in particular, to a turbine guide. Background technique [0002] In the existing gas turbine engines and ground gas turbines, the gas turbine guide is one of the important stator parts and flow channel parts. It is located at the front end of the turbine parts. Potential energy is converted into kinetic energy. The turbine casing and the turbine outer ring mainly play the role of supporting, containing and controlling the tip clearance. [0003] Existing gas turbine guides are generally composed of guide vane sectors, which are fixed by guide brackets; the turbine outer ring is usually segmented and designed as sectors with hooks, which are connected to the turbine casing through hooks. Since the gas turbine guide and the turbine outer ring are composed of fan-shaped parts, and the guide mounting bracket leads to a large number of parts, a large number of precision structures,...
