Unmanned aerial vehicle device working on heavy load condition and control method

Abstract

The invention belongs to the field of unmanned aerial vehicles and provides an unmanned aerial vehicle device on the heavy load condition and a control method. The unmanned aerial vehicle device on the heavy load condition comprises an unmanned aerial vehicle body structure and a master control unit controlling various systems of the unmanned aerial vehicle to be operated normally. The unmanned aerial vehicle device on the heavy load condition further comprises an air bag device providing upward tension for the unmanned aerial vehicle. The air bag device is arranged above the unmanned aerial vehicle body structure and filled with low-density gas with the density lower than that of air. The air bag device is further connected with an exhaust device for exhausting gas volume inside the air bag device. The tension generated by the air bag device is adjustable by controlling the gas volume inside the air bag device. According to the device, onboard energy consumption of an unmanned aerial vehicle on the heavy load condition is lowered, and the flight working time of the unmanned aerial vehicle is prolonged, so that the working efficiency of the unmanned aerial vehicle is achieved, the working time of the unmanned aerial vehicle on the heavy load condition is prolonged, the working range of the unmanned aerial vehicle on the heavy load condition is enlarged, and the defect that use of the unmanned aerial vehicle is limited on the heavy load condition is overcome.
