An airship and its long-term floating capacity maintenance method are disclosed. The airship includes an airship capsule and a pod at bottom. A renewable fuel cell and a water tank communicated with each other are arranged in the pod. The water tank is provided with a water inlet connected with a filling aircraft outside the airship. The airship capsule is provided with a solar cell. The interior of the airship capsule is provided with a hydrogen storage bag. The solar cell is electrically connected with the renewable fuel cell. The renewable fuel cell can use electric energy provided by the solar cell to electrolyze water provided by the filling aircraft into hydrogen and supplement the hydrogen to the hydrogen storage bag. The airship can supplement hydrogen to the airship capsule by electrolyzing water to reduce the phenomenon of insufficient gas in the airship capsule.

Airship and long-term floating capacity maintenance method thereof

A power supply and distribution device for solar-powered aircraft includes at least two power supply and distribution sub-systems having same configurations. A disconnection of an electrical connection between a plurality of components of each power supply and distribution sub-system can be controlled through a first switch. An electrical connection between the same components of the power supply and distribution sub-systems can be established by controlling a second switch. The power supply and distribution device for solar-powered aircraft has a centralized-distribution design. Specifically, each power supply and distribution sub-system is designed in a centralized mounting manner and has separated power supply and power distribution functions that can work separately. The power supply and distribution systems are designed in a distributed mounting manner which is suitable for solar aircrafts having characteristics of large wingspan and distributed propulsion system, thereby effectively reducing the concentrated stress.
