水陆两栖飞机起落架水环境适应性验证要求与方法

通过水浸润、水冲击、结冰、海洋腐蚀等水环境对起落架的影响及其损伤失效模式的分析研究，提出了水陆两栖飞机起落架水环境验证要求。综合考虑环境适应性验证规范、标准的合理选用和剪裁，建立了水陆两栖飞机起落架水环境试验验证方法，涵盖静水密试验、连续水冲击试验、泥沙水试验、结冰试验以及海洋环境腐蚀试验的条件和方法，以期为水陆两栖飞机起落架的环境适应性设计与验证提供支持。

Requirements and Methods for Water Environment Adaptability Verification of Landing Gear of Amphibious Aircraft

The work aims to propose the verification requirements of water environment for amphibious aircraft landing gear by analyzing and studying the impact of water environment such as water immersion, water impact, icing and marine corrosion on landing gear and the corresponding damage failure mode. The verification specifications and standards of environment adaptability were reasonably selected and extracted to establish the verification method for water environment test of amphibious aircraft landing gear. This verification method covered the conditions and methods of hydrostatic watertight test, continuous water impact test, sediment water test, icing test and marine corrosion test, so as to provide support for the design and verification of environment adaptability of amphibious aircraft landing gear.
