Formula and the combination of three formulas.Unmanned plane can realize dual-use, and civilian unmanned plane is used for meteorological disaster monitoring, pesticide spraying and ground
Matter is investigated.Must there is preferable motive drive source in flight course, provide for UAV and continue sufficient energy.At present, most
Energy supply method has solar battery array scheme and fuel cell solutions.The conversion efficiency of solar battery array scheme is low, and
A large amount of solar panel need to be carried, and limited by daytime at night, be difficult to meet the requirement of UAV continuous firing；Fuel
The conversion efficiency of battery is high, however it is necessary that and carries a large amount of relevant device, such as electrolyser, temperature control system, fuel tank etc.,
Thus the load of aircraft is had higher requirement.
Summary of the invention
