摘要
旋翼转速是影响直升机飞行性能的一个重要因素,环境温度变化对换算旋翼转速产生影响,同时换算旋翼转速大小也能体现旋翼压缩性影响程度。在保持其他参数不变的情况下,因环境温度变化导致的换算旋翼转速变化,分析低温和高温两种状态下的换算旋翼转速,对比直升机功率系数变化,研究不同换算旋翼转速对直升机性能带来的影响。
Rotor speed is an important factor to affect the flight performance of a helicopter, the change of the environment temperature has an effect on conversion of rotor speed, and the size of conversion rotor speed can also reflect the influence of rotor blade compressibility. This paper studied keeping other parameter to invariable and contrast the conversion of rotor speed, which is caused by the change of the environment temperature. By comparing the power coefficient of the helicopter, analyzed the influence of different conversion of rotor speed on the performance of the helicopter under the condition of two kinds of extreme conditions.
