The invention provides a double-rotor aircraft. The double-rotor aircraft comprises an aircraft body, a rotor assembly and a power transmission assembly, the rotor assembly comprises a first set of rotor wings and a second set of rotor wings, the first set of rotor wings and the second set of rotor wings are arranged in parallel up and down and located above the fuselage, the first set of rotor wings are fixedly supported on a rotor wing shaft, and the rotor wing shaft is sleeved with the second set of rotor wings; the power transmission assembly comprises an engine, a first connecting rod, acrank and a second connecting rod, the output end of the engine is connected with the rotor shaft, the two ends of the crank are connected with one end of the first connecting rod and one end of the second connecting rod respectively, the other end of the first connecting rod is connected with the rotor shaft, and the other end of the second connecting rod is in transmission connection with the second rotor. The engine drives the rotor wing shaft to rotate so as to enable the first set of rotor wings to rotate, the second set of rotor wings transmit power transmitted to the rotor wing shaft tothe second set of rotor wings through the second connecting rod, the crank and the first connecting rod, the two sets of rotor wings generate lift force, and therefore the sailing capacity of the aircraft is improved.
本发明提供了一种双旋翼飞行器,包括:机身、旋翼组件及动力传动组件;旋翼组件包括第一组旋翼和第二组旋翼,第一组旋翼和第二组旋翼上下平行布置位于机身的上方,第一组旋翼固定支撑在旋翼轴上,第二组旋翼空套在旋翼轴上;动力传动组件包括发动机、第一连杆、曲柄及第二连杆,发动机的输出端与旋翼轴连接,曲柄的两端分别与第一连杆的一端和第二连杆的一端连接,第一连杆的另一端与旋翼轴连接,第二连杆的另一端与第二组旋翼传动连接。通过发动机带动旋翼轴转动从而使第一组旋翼转动,第二组旋翼通过第二连杆、曲柄及第一连杆,将传递至旋翼轴上的动力传送至第二组旋翼上,两组旋翼均产生升力,从而实现提高飞行器的航行能力。
