Abstract

The invention relates to a method for evaluating the integrity of an aero-generator, which belongs to the field of aeronautical technology, and includes: first: determining typical materials of an aero-engine, the typical materials including rubber materials and aluminum alloy materials; second: determining rubber materials and The weight of the aluminum alloy material; the third: establish the integrity models of the rubber material and the aluminum alloy material according to the damage form of the rubber material and the aluminum alloy material during the storage process; the fourth: calculate the generator’s integrity. The integrity evaluation method of the aero-generator of the invention can accurately evaluate the integrity of the aero-generator through a mathematical model, and has operability.

Description

technical field [0001] The invention belongs to the technical field of aviation, and in particular relates to a method for evaluating the integrity of an aviation generator. Background technique [0002] Under long-term storage conditions, the integrity of aero-engines is uncertain, and if it is applied to actual engineering, it will limit the performance of engineering systems. Therefore, there is a need for an aero-engine integrity assessment method to assess the integrity of aero-engines under long-term storage conditions. Contents of the invention [0003] The purpose of the present invention is to provide a method for assessing the integrity of an aero-generator, which is used to solve the problem that there is no accurate calculation model for the integrity of an aero-engine. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a method for evaluating the integrity of an aero-generator, which includes: [0005] ...
