Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the middle casing of the turbine engine of the present invention will be further described in detail through the following embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar ex...

Abstract

The invention relates to the technical field of turbine engines, in particular to a middle receiver of a turbine engine. The middle receiver comprises a receiver outer ring and a receiver inner ring,wherein the receiver outer ring sleeves the receiver inner ring; the axial central line of the receiver outer ring, the axial center line of the receiver inner ring and the axis of an engine shaft aresuperposed; a gap is formed between the receiver outer ring and the receiver inner ring; a plurality of guide blades are arranged between the receiver outer ring and the receiver inner ring; and theguide blades are uniformly distributed in the peripheral direction around the axis of the engine shaft for guiding the direction of gas flow. According to the middle receiver of the turbine engine provided by the invention, the middle receiver integrates the action of a turbine guider, and the turbine guider does not need to additionally arrange for guiding gas flow, so that engine components canbe reduced, and therefore, the engine part quantity and engine weight are reduced. The engine is more compact in layout, and integral length of the engine is shortened.

Description

technical field [0001] The invention relates to the technical field of turbine engines, in particular to an intermediate casing of a turbine engine. Background technique [0002] The casing is one of the important parts of the aero-engine. It is the base of the entire engine and the main load-bearing part of the aero-engine. Its shape and structure are complex. Different engines and different parts of the engine have different casing shapes. The function of the casing parts determines the shape of the casing, but their basic features are components composed of a cylindrical or conical shell and a support plate. Due to the difficulty in designing the casing parts and the long cycle, the design of the entire engine In the design of the casing, the design of the casing accounts for a considerable proportion, and improving the design efficiency of the casing is of great significance to the design of the complete compression engine. [0003] As the middle part of the turboshaft ...
