The invention provides an unmanned aerial vehicle flight assisting device and an unmanned aerial vehicle flight system.The unmanned aerial vehicle flight assisting device is used for assisting an unmanned aerial vehicle to take off and comprises a platform and a driving assembly; the driving assembly is used for driving the platform to rotate; the platform is provided with at least two parking spaces, and the parking spaces are used for parking and fixing the unmanned aerial vehicle; a locking mechanism is arranged at the position of each parking space; under the condition that the rotating speed of the platform is smaller than the preset rotating speed, the locking mechanism is used for locking the unmanned aerial vehicle; and under the condition that the rotating speed of the platform isnot smaller than the preset rotating speed, the locking mechanism is used for releasing the unmanned aerial vehicle. According to the unmanned aerial vehicle flight assisting device provided by the embodiment of the application, the circular rotary motion is adopted to replace the linear motion of a traditional ejection device, so that the unmanned aerial vehicle can obtain the required takeoff power and initial speed through the preset circular motion before takeoff; the space area occupied by the acceleration distance can be reduced, the use cost is reduced, and the economy of unmanned aerial vehicle application is effectively improved.

本申请提供了一种无人机助飞装置及无人飞行系统，无人机助飞装置用于辅助无人机起飞，装置包括平台和驱动组件；驱动组件用于驱动平台转动；平台设置有至少两个停机位，停机位用于停放固定无人机；停机位的位置设置有锁止机构；在平台的转速小于预设转速的情况下，锁止机构用于锁紧无人机；在平台的转速不小于预设转速的情况下，锁止机构用于释放无人机。本申请实施例提供的无人机助飞装置，本申请实施例的这种无人机助飞装置，采用圆周回转运动代替传统弹射装置的直线运动，因此，无人机在起飞前可以通过预设的圆周运动获得需要的起飞动力及初速度，可以减小加速距离对于空间面积的占用，降低使用成本，有效提升无人机应用的经济性。
