Study on the airworthiness certification technical system and key contents of aircraft tire burst

Abstract

The research on aircraft tire blasting approval technology is of great significance to promote aircraft forensics and improve aircraft safety. In order to further promote the development of tire burst airworthiness technology and standardize the technical system, the development status and differences of applicable tire burst airworthiness regulations in various countries are tracked and investigated. Based on the engineering practice of domestic civil aircraft on the latest international tire burst airworthiness certification, an airworthiness certification technology system for aviation tire explosions in accordance with clause CS 25.734 is established, the verification process, verification objects, related clauses, and certification technical indicators are refined, and the expected safety level of CS 25.734 is fully interpreted. The key elements and suggestions for airworthiness certification that require special attention are proposed. The results show that the newly revised proprietary clause CS 25.734 of the EASA requires higher requirements and clearer tire burst modes. The airworthiness certification technology system, certification elements, and recommendations for aviation tire explosions mentioned in this article are validated in the airworthiness certification of a domestic large passenger aircraft, which can provide guidance for industry reviewers and designers, and is a new breakthrough in the field of certification technology in China.
