FIELD: aviation.
SUBSTANCE: invention relates to unmanned aerial vehicles and is intended for monitoring large areas of the earth's surface. Unmanned aerial vehicle comprises body-fuselage, power plant, vessel with hydrogen, main tank with hydrogen located outside fuselage housing and connected to series-connected compressor, additional tank with hydrogen and fuel elements installed inside housing. Main container with hydrogen is made with possibility of changing shape and is divided into sections by hydropermeable partitions, each of which is connected to small capacity through compressor.
EFFECT: invention is aimed at increasing the flight duration of the vehicle owing to the use of hydrogen reserve.
