The invention provides a heavy-load longitudinally-arranged double-rotor unmanned aerial vehicle platform. The platform comprises a rack, a rotor system, a flight control system and a power system. Reaction torques generated by the two rotor systems with opposite rotating directions can be mutually balanced, a tail rotor does not need to be independently designed, and the efficiency is higher; compared with a traditional unmanned aerial vehicle, the longitudinal double-rotor design is adopted, so that the loading capacity is more excellent; if the power system breaks down and cannot normally take off and land, unpowered safe forced landing can be achieved according to inertia due to the fact that the one-way bearing is installed on the main shaft of the rotor wing system, and compared withan existing multi-shaft (three or more shafts) unmanned aerial vehicle, the safety is higher; the crosswind disturbance resistance during hovering is excellent, and the large control allowance is achieved; due to the fact that the range of the longitudinal gravity center is large, the fuselage can be integrally designed to be large, a larger load cabin is further obtained, and more goods can be transported.
本发明提供了一种大载重纵列双旋翼无人机平台,包括机架、旋翼系统、飞控系统以及动力系统。本发明中两个旋转方向相反的旋翼系统产生的反作用扭矩可以互相平衡掉,无需单独设计尾桨,效率更高;相比于传统的无人机,采用纵向双旋翼的设计使得载重能力更为优秀;若动力系统出现故障,导致无法正常起降时,由于旋翼系统的主轴安装有单向轴承,可根据惯性实现无动力安全迫降,相比于目前的多轴(三轴以上)无人机,其安全性更高;悬停时的抗侧风扰动能力优秀,具有较大的操纵余量;由于纵向重心范围大,因此可将机身整体设计的比较庞大,进一步得到更大的载荷舱,可运输更多的货物。
