摘要
首先对尾桨的气动特性进行了分析,将尾桨所受气动力进行了严格的公式推导,根据公式将尾桨空气动力的研究转换为对公式中相关参数的研究,然后对尾桨叶片进行了贴片标定,最后通过直升机飞行试验验证了定性分析得到的尾桨气动规律,为后续的尾桨载荷试飞提供了支持。
In this paper, the aerodynamic characteristics of the tail rotor were analyzed, the aerodynamic force of the tail rotor was rigorously deduced, and the aerodynamic research of the tail rotor was transformed into the study of the relevant parameters based on the previous formula. Then, the tail rotor blades were calibrated, tail rotor pneumatic law was verified by the helicopter flight test as well as provided support to the following tail rotor load test.
