The invention discloses an unmanned helicopter transmission system and a using method, and relates to the field of helicopter transmission system.The transmission system comprises an engine and a tensioning device, and the engine is located below a main speed reducer of a rotor shaft; an output shaft of the engine is in transmission connection with a main reducing input shaft of the main reducing gear through a belt; the tensioning device is used for controlling the belt to be switched between the tensioning state and the loosening state, and separation and combination of power and rotor wing transmission are achieved. The invention further provides a use method. Vibration of an engine can be isolated through the vibration isolation advantage of belt transmission, meanwhile, high integration of the whole transmission system is achieved, miniaturization and light weight are achieved, balancing of the gravity center of an aircraft is facilitated, system complexity and ineffective weight are reduced, reliability is improved, the weight of the unmanned helicopter is reduced, and the service life of the whole helicopter is prolonged.

    本发明公开了一种无人直升机传动系统及使用方法,涉及直升机传动系统设计领域,传动系统包括:发动机和张紧装置,所述发动机位于旋翼轴的主减速器下方;所述发动机的输出轴与主减速器的主减输入轴通过皮带传动连接;所述张紧装置用于控制皮带在张紧状态和松弛状态之间切换,实现动力与旋翼传动的分离和结合;并以此提出了一种使用方法;本发明,不仅能够通过皮带传动的隔振优势隔离发动机的振动,同时实现整套传动系统高度集成,实现小型化和轻量化,有利于飞机重心配平,减少了系统复杂度和无效重量,提高了可靠性,降低了无人直升机的重量,提高了全机的寿命。
