Method for weaving inclusive ring of gas compressor of engine

Abstract

The invention provides a method for weaving a containing ring of a gas compressor of an engine. The method is characterized by comprising the following steps: weaving a three-dimensional orthogonal intertexture by a three-dimensional weaving machine as a main part of the containing ring; weaving holes on the three-dimensional orthogonal intertexture by a double side weft insertion method; weavingthe edge part of the containing ring of the three-dimensional orthogonal intertexture through manual hemming; and seaming the containing ring by a step shaped lapping method. The method uses the three-dimensional weaving machine to weave the three-dimensional orthogonal intertexture of the containing ring, uses the double side weft intersection method to directly weave part interface reserved holes, and is simple and practical. The containing ring is woven by high performance fibers, has compact structure and high impact resistance, can effectively prevent severe threat on other parts of a plane because high-speed splinters generated by an unexpectedly damaged vane puncture the shell of the engine under a condition of high speed operation of the engine.

Description

technical field [0001] The invention relates to a weaving method for a containment ring of an engine compressor, belonging to the technical field of engines. Background technique [0002] The engine is an important part of the aircraft, and it can be called the heart of the aircraft. It provides flight power for the aircraft, and its operating status directly determines the safety performance of the aircraft. Because the first-stage working blades of the compressor or fan of the aircraft are at the engine inlet, they are easily damaged by foreign objects and broken; Compared with the turbofan engine, the length of the first-stage fan blade is nearly 1m or more than 1m. If it breaks from the root, the centrifugal force thrown by the fragment is as high as 50-60t. If it breaks through the casing, the harm to the aircraft can be imagined And know. Moreover, the rotational speed of the aircraft engine rotor is very high, up to 50,000-60,000 rpm. During the high-speed operatio...

Problems solved by technology

However, the containment ring of the fan casing made by the winding method has the following disadvantages: the impact resistance of the containment ring is low, and the containment ring made by the winding method needs to be coated with resin to be cured into a composite material, which makes the containment ring heavier
