Abstract

The invention provides an aluminum alloy material design verification method for airworthiness certification, which comprises the following steps: matching airworthiness verification parameters of analuminum alloy material with a verification database Q1: when the airworthiness verification parameters of the aluminum alloy material are successfully matched with the verification database Q1, determining that the aluminum alloy material passes verification; when the airworthiness verification parameters of the aluminum alloy material are not successfully matched with the verification database Q1, matching the airworthiness verification parameters of the aluminum alloy material with the general standard database Q2, and when the airworthiness verification parameters of the aluminum alloy material are successfully matched with the general standard database Q2, determining that the aluminum alloy material passes verification; and when the airworthiness verification parameters of the aluminum alloy material are not successfully matched with the general standard database Q2, and when the airworthiness verification parameters of the aluminum alloy material are successfully matched with the basic global database Q3, determining that the aluminum alloy material passes verification. According to the embodiment of the invention, the airworthiness verification efficiency of the aluminum alloy material can be greatly improved, the reliability is high, the reliability can be improved, and the examination efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of civil aircraft airworthiness, in particular to an aluminum alloy material design verification method for airworthiness certification. Background technique [0002] The metal materials used on aircraft mainly include aluminum alloy, steel, titanium alloy and copper alloy. Among them, aluminum alloys mainly include 2024, 2124, 7075, 7050, 7475 and other commonly used aluminum alloy grades with excellent performance, etc., and high-performance aluminum alloys mainly include 7150, 7055, 2524, 2026 and 2024HDT. [0003] After research, the applicant knows that the materials selected for civil aircraft must comply with the relevant provisions of the Airworthiness Regulations. The selection of materials should consider the requirements of airworthiness, the materials have passed the necessary tests, have certain experience in use, and meet the requirements of the corresponding material specifications. In terms...
