All aircraft structures are exposed to a wide range of operational environments and contaminants. Of particularconcern are contaminants such as salt water, hydraulic fluid and fresh water - especially when combined withstatic and fatigue loading in helicopter structures. A design of experiment approach will be used to identifyand isolate mechanical parameters and exposure conditions of interest. To support this design of experimentprocess, surveys of operators and maintainers will be conducted to identify typical contamination events andspecific maintenance concerns. Several rounds of mechanical testing following exposure to variouscontaminants. Basic finite element analysis will also be carried out on various configurations to examine theeffect of exposure on mechanical properties. Recommendations for maintenance planning and repair strategieswill be provided to the industrial partner.

所有飞机结构都暴露在各种运行环境和污染物中。特别值得关注的是盐水、液压油和淡水等污染物，尤其是在直升机结构中与静态和疲劳载荷相结合时。将使用实验方法设计来识别和隔离感兴趣的机械参数和暴露条件。为了支持实验过程的设计，将对操作员和维护人员进行调查，以确定典型的污染事件和具体的维护问题。暴露于各种污染物后进行多轮机械测试。还将对各种配置进行基本有限元分析，以检查暴露对机械性能的影响。将向工业合作伙伴提供维护计划和维修策略的建议。
