本SAE航空航天信息报告（AIR）概述了评估直升机安装中燃气轮机发动机动力装置所处振动环境的推荐程序。发动机振动分析通常在发动机/直升机配置的初始认证或重大修改后一次性进行。该空气处理发动机基本壳体结构上测得的线性振动，而不是驱动轴系中的扭转振动或发动机内部件（如压缩机或涡轮翼型）的振动。 总之，本节讨论了发动机制造商关于发动机振动的“安装测试规范”方面，并提出了适当的测量方法

This SAE Aerospace Information Report (AIR) outlines a recommended procedure for evaluation of the vibration environment to which the gas turbine engine powerplant is subjected in the helicopter installation. This analysis of engine vibration is normally demonstrated on a one-time basis upon initial certification, or after a major modification, of an engine/helicopter configuration. This AIR deals with linear vibration as measured on the basic case structure of the engine and not, for example, torsional vibration in drive shafting or vibration of a component within the engine such as a compressor or turbine airfoil. In summary, this AIR discusses the engine manufacturer's "Installation Test Code" aspects of engine vibration and proposes an appropriate measurement method
