The invention provides a noise reduction method of a miniature single-rotor unmanned helicopter platform. The noise reduction method adopts a mute noise reduction main tail rotor module and/or a motordirect drive transmission module and/or a mute brushless motor module. After noise reduction by the method provided by the invention, the unmanned aerial vehicle at the same level has the performancethat the fixed-wing unmanned aerial vehicle cannot hover at a fixed point. The low-noise level of the multi-rotor unmanned aerial vehicle is exceeded, and good efficiency and endurance advantages areachieved.
本发明提供一种微型单旋翼无人直升机平台的降噪方法,降噪方法包括采用静音降噪主尾桨模块和/或采用电机直驱传动模块和/或采用静音无刷电机模块。经过本发明提供的方法降噪后在同级别无人机中具备固定翼无人机无法定点悬停的性能。超越多旋翼无人机的低噪音水平,以及拥有良好的效率以及续航优势。
