Civil aircraft structural member laser forming technology airworthiness conformity verification method

Abstract

The invention relates to a civil aircraft structural member laser forming technology airworthiness conformity verification method which comprises the following steps: step 1, determining aircraft structural member laser forming technology raw material specifications according to laser forming material performance indexes and design requirements, and submitting the specifications to an airworthiness department for examination; step 2, determining laser forming process parameters and submitting the parameters to the airworthiness department for examination; step 3, determining material performance indexes of the laser forming blank and material structure special coefficients of the blank; step 4, submitting the performance indexes of the laser forming blank material determined in the step 3 to the airworthiness department for examination; step 5, formulating a structural part performance data test outline, verifying whether the laser forming structural part can meet the structural design requirement or not through a structural part performance data test, and enabling the verification process of the structural part test to be visually verified by the airworthiness department; and step 6, submitting the laser forming raw material specification, the blank material performance index, the structural performance data, the raw material specification verification test outline and the structural performance data verification test outline to the airworthiness department for examination.

Description

technical field [0001] The invention belongs to the technical field of airworthiness compliance verification, and relates to a method for verifying airworthiness compliance of civil aircraft structural parts laser forming technology. Background technique [0002] Civil aircraft pursue long life, high weight reduction, safety and low cost, and new materials, new structures and new processes complement each other. The traditional manufacturing method produces aircraft parts, and its structural design, material selection, manufacturing, maintenance and other modules are independent of each other. In the process, it is inevitable that there will be problems such as poor connection, rework or delay. Technology solves this problem very well. It integrates the above processes, shares a data platform, and provides real-time feedback of opinions from all sides, realizing the seamless connection between design and manufacturing. [0003] As a new technology, laser forming technology ...
