介绍了民用飞机辅助动力装置安装系统静强度设计的适航标准要求和设计载荷。以某型飞机辅助动力装置安装系统静强度设计为例,介绍了辅助动力装置安装系统的静强度分析和试验验证方法。安装拉杆的试验应力值和理论应力值的对比分析表明对安装系统的理论分析方法保守,其设计满足静强度要求和适航条款要求。
The airworthiness standard requirements and design loads of the static strength design of the civil aircraft auxiliary power unit installation system are introduced. Taking the static strength design of a certain type of aircraft auxiliary power plant installation system as an example, the static strength analysis and experimental verification methods of the auxiliary power plant installation system are introduced. The comparative analysis of the test stress and the theoretical stress of the mounting rod shows that the theoretical analysis method of the installation system is conservative and its design meets the requirements of static strength and airworthiness terms.
