Problems solved by technology

The pressure balance and buoyant weight balance cannot be reliable at the same time due to the influence of the temperature change law inside the boat, so that the airship cannot operate normally. The total buoyancy cannot balance the total gravity, making it difficult for the airship to rise; during the descent, the temperature inside the boat is too high

Embodiment approach

[0092] The hydrogen bag is covered by the helium bag, which is more conducive to the safety of the hydrogen bag. Since hydrogen is the lightest gas in the boat, the hydrogen bag is on the top of the airship, and the top of the airship body needs to be treated safely. In order to simplify the system design, the hydrogen is connected to the hydrogen bag and the hydrogen recovery and release system through a pipeline. The hydrogen recovery and release system is similar to the regenerative fuel cell, except that it does not carry a special oxygen storage system. The oxygen-containing air in the boat is compressed in the first stage and stored in the second stage for use by the fuel cell. Compression is conducive to the simplification of the system and the improvement of fuel cell efficiency. Since there is no oxygen storage system, the oxygen after water electrolysis is discharged into the air bag, and the discharged oxygen needs to be fully extracted with water to make it complet...

Abstract

The invention relates to a stratospheric airship with a hydrogen adjusting device, and belongs to the technical field of buoyancy adjusting of stratospheric airships. A hydrogen bag and air bags are included in an airship body in the stratospheric airship, a hood is included in the hydrogen bag, and a pressure sensor is included in the hood. A buoyancy lift adjusting system and a hydrogen storage ballast are included in a pod in the stratospheric airship. A buoyancy adjusting system comprises a hydrogen treatment system, a fuel storage box, an air storer, a fuel battery, an energy management system, a lithium battery, a water electrolyzer, a hydrogen purifier and a water storer. A hydrogen generation device is a container, and the middle of the container is divided by separation plates into four cavities. The hydrogen generation device is fixedly connected to the outside of the pod through a separating and unlocking device, and the hydrogen generation device is thrown out from the pod when the separating and unlocking device is opened.

Description

technical field [0001] The invention relates to a stratospheric airship containing a hydrogen regulating device, belonging to the technical field of buoyancy adjustment of the stratospheric airship. Background technique [0002] The stratospheric airship is a near-space vehicle that is lighter than air. It works at an altitude of about 20 kilometers and can stay in the air for a long time. It is very suitable as a new information platform for broadband communication, high-precision earth observation, and regional early warning. , has become a research hotspot at home and abroad. [0003] The airship must meet two balances during operation, one is pressure balance and the other is buoyancy balance. Pressure balance means that the pressure difference inside and outside the airship must be kept within a certain range, such as about 500pa. The buoyancy balance is that the total buoyancy and total gravity of the airship meet the needs of the airship to rise / station / return to a ...
