The invention relates to a rotorcraft pre-rotation system which comprises a rack, an engine and a propeller disc, the engine is arranged on the rear portion of the rack, the propeller disc is erected on the top of the rack, the rotorcraft pre-rotation system further comprises a driving module and a transmission module, the driving module is arranged on the front portion of the engine, and the transmission module is installed between the engine and the rack; the rear end of an output shaft of the engine is connected with and drives a propelling propeller, the front end of the output shaft of the engine is connected with and drives the driving module, the driving module is separably connected with the access end of the transmission module, and the output end of the transmission module is connected with and drives the propeller disc to rotate; compared with an existing design, the front end and the rear end of the output shaft of the engine are completely utilized, the front end is used for driving the prerotation system, and the rear end is used for driving the propulsion propeller. According to the design, the complexity of the pre-rotation system is greatly reduced, and the power of the pre-rotation system is directly generated by the front end of the output shaft of the engine.

    本发明涉及一种旋翼机预旋系统,包括机架、发动机和桨盘,发动机设置在机架的后部,桨盘架设在机架顶部,还包括驱动模块和传动模块,驱动模块设置在发动机前部,传动模块安装在发动机和机架之间;所述发动机输出轴的后端连接并驱动一推进螺旋桨,发动机输出轴的前端连接并驱动所述驱动模块,该驱动模块可分离地与传动模块的接入端连接,传动模块的输出端连接并带动桨盘转动;本发明相较于现有设计,将发动机输出轴的前后两端完全利用起来,前端用于驱动预旋系统,后端用于驱动推进螺旋桨。此设计大大降低了预旋系统的复杂度,该设计的预旋系统的动力由发动机输出轴的前端直接产生。
