Description

Primary and secondary formula unmanned aerial vehicle Technical Field The invention relates to the technical field of unmanned aerial vehicles, in particular to a mother-son unmanned aerial vehicle. Background Along with unmanned aerial vehicle technology development, unmanned aerial vehicle is more and more applied to the long-distance accurate material of puting in, and this just needs unmanned aerial vehicle can realize long-time and long range flight, and can load more materials. The existing unmanned aerial vehicle needs to realize long-time and long-range flight, the unmanned aerial vehicle has large volume and large take-off weight, and a layout mode with high pneumatic layout stability is needed. The unmanned aerial vehicle has the advantages that the unmanned aerial vehicle is large in size and easy to knock down, the aircraft is heavy due to large take-off weight, the minimum speed is high, the throwing precision is poor, and the aircraft is poor in maneuverability and flexibility due to high-stability pneumatic layout and large size. In addition, in order to realize the throwing supply to appointed place, the unmanned aerial vehicle is required to be small in size, high in flexibility, and the unmanned aerial vehicle is enabled to take off in small weight due to the high maneuverability and the small size, and more energy sources cannot be loaded to realize long-endurance flight.
