Embodiment 1

[0029] Embodiment 1, a kind of small unmanned airship that uses hydrogen-helium mixed energy source, such as figure 1 As shown, an airbag 1 and a power unit 4 are included.

[0030] The airbag 1 is filled with hydrogen / helium mixed gas mixed in a certain proportion as the buoyancy gas of the airship. The power plant 4 includes an interconnected hydrogen fuel cell stack 5 and an electric motor 6 .

[0031] The airbag 1 is connected to the hydrogen fuel cell stack 5 through the hydrogen-helium mixed gas circuit 2, and is used to provide the reaction hydrogen / helium mixed gas to the hydrogen fuel cell power system. Helium is an inert gas and does not participate in the fuel cell reaction; external air passes through The air circuit 3 is connected with the hydrogen fuel cell stack 5 for providing reactive oxygen to the hydrogen fuel cell power system.

[0032] The hydrogen-helium mixed gas circuit 2 is also equipped with a water vapor separation device 7 at the gas return port o...

Abstract

The invention provides a small unmanned airship using hydrogen and helium hybrid energy. The small unmanned airship comprises an air bag and a power device; the air bag is filled with hydrogen/helium mixed gas mixed according to a certain proportion to serve as floating gas of the airship; the power device comprises a hydrogen fuel battery pack and a motor which are connected with each other; the air bag is connected with the hydrogen fuel battery pack through a hydrogen and helium hybrid gas loop and is used for providing reaction hydrogen/helium mixed gas for a hydrogen fuel battery power system; and external air is connected with the hydrogen fuel battery pack through an air loop and is used for providing reaction oxygen for the hydrogen fuel battery power system. The hydrogen/helium mixed gas is used for replacing pure hydrogen to serve as fuel of the battery, potential safety hazards of the fuel battery in the operation process can be effectively avoided, and the service life of a fuel battery stack is prolonged. Meanwhile, due to the fact that the hydrogen is directly stored in the air bag, dependence on a storage medium steel cylinder is reduced, the dead weight of the airship is reduced, the load capacity of the airship is improved, and the purpose of miniaturization is achieved.

Description

technical field [0001] The invention relates to the field of aerostat design, in particular to a small unmanned airship using hydrogen-helium mixed energy. Background technique [0002] An airship is an aircraft with propulsion and flight control, and generally includes a helium-filled hull, a pod located under the hull, an empennage for stabilizing control, and a propulsion system that provides power. In recent years, with the enhancement of environmental awareness and the development of new energy technologies, the research on fuel cells as the driving force of airships has attracted widespread attention. [0003] The structure of the hydrogen energy airship that has appeared today includes a hull and a pod. The pod is equipped with a hydrogen fuel cell device that provides power for the airship. The buoyant gas is separated from the fuel gas. form of energy and has no other role. [0004] At present, the storage method of hydrogen fuel is in the form of high-pressure st...
