传动系统是直升机关键系统之一,它将发动机的动力传递给旋翼、尾桨,并传动交流发电机、液压泵等其他附件。传动系统振动过大会严重影响飞行安全。文章以某型直升机为例,简要介绍了传动系统工作原理,并对其安装国产化传动系统前后的振动分析结果进行对比。
Transmission system is one of the key helicopter system, it will be the engine power transmitted to the rotor, tail rotor, and drive alternator, hydraulic pump and other accessories. Transmission system vibration over the General Assembly has a serious impact on flight safety. Taking a type of helicopter as an example, this paper briefly introduces the working principle of the transmission system and compares the vibration analysis results before and after the localization of the transmission system.
