Abstract

The invention provides a method for blanking a composite material inlet, which relates to the technical field of composite materials, and includes the following steps: S1: defining a blanking coordinate system according to the curved surface structure of the inlet; S2: according to the inlet The curved surface structure and the blanking coordinate system define the ply angle of the air inlet; S3: according to the ply angle of the air inlet, discretize the ply of the air inlet to obtain Layer block; S4: Expand and project the layer block into a planar figure to obtain a blanking diagram of the air inlet. The blanking method of the composite material air inlet provided by the present invention converts the curved surface structure of the air inlet into a discrete block-shaped curved surface structure according to the laying angle, and then unfolds the block-shaped curved surface structure to improve the The accuracy of the blanking is ensured.

Description

technical field [0001] The invention relates to the technical field of application of composite materials, in particular to a method for blanking composite material air inlets. Background technique [0002] The air inlet is the channel for introducing air into the aircraft engine, and it is one of the key components to ensure the normal operation of the engine. Its main function is to provide a certain flow of air for the engine, so as to ensure that the air intake air field can meet the requirements of the normal operation of the compressor and the combustion chamber. Requirements, therefore, the shape of the inlet is complex, usually variable cross-section structure. [0003] The blanking method of the traditional variable cross-section composite material inlet is usually to wrap the prepreg material on the inlet paving tooling, and then manually cut into blocks, and then scan the manually cut blocks, and analyze each part according to the scanning results. Carry out digi...
