Abstract
Description
Technical Field
[0001] The present application relates to the field of aviation aerostats, and in particular to a liquid hydrogen electric heating airship. Background Art
[0002] Hydrogen airships are extremely dangerous due to the flammable and explosive nature of hydrogen; the helium used in helium airships is expensive and its production and supply sources are easily limited, and the subsequent maintenance and required capsule materials have high requirements; hot air balloons have limited range due to fuel restrictions and cannot fly in a direction due to lack of power. Summary of the invention
[0003] The purpose of this application is to provide a liquid hydrogen electric heating airship design to achieve low-cost manufacturing of the airship.
[0004] Liquid hydrogen electric thermal airship uses liquid hydrogen as a fuel source, generates electricity through electrochemical reactions in fuel cells, and then uses electric heating to heat the air to provide buoyancy, regulate the temperature to achieve the rise and fall of the airship, and the electric motor provides power output.
[0005] Furthermore, the electric heating method includes resistance heating, induction heating, and infrared heating.
[0006] The electric heaters are distributed in the airship singly or in multiple locations to evenly heat the air in the airship. The temperature of the heated air is used to control the buoyancy of the airship, thereby controlling the rise and fall of the airship.
[0007] Furthermore, the airship's attitude is controlled by electric motors instead of traditional rudders, and multiple distributions of electric motors can not only provide thrust but also change the thrust size and direction.
[0008] This application has the following advantages: 1. This application utilizes heated air to generate buoyancy, and hot air is safer and more reliable than hydrogen.
[0009] 2. Hot air is one-time use, and subsequent maintenance is easier than helium. Hot air is easy to produce and low in cost. After large-scale use, the source supply is not limited.
[0010] 3. The airship is electrically driven, which has a simpler structure and less mass than hydraulic and mechanical transmission. Traditional rudders are limited by flight speed and have slow steering, while multi-motor drives respond quickly and accurately.
[0011] 4. Liquid hydrogen has high energy density and requires less fuel. BRIEF DESCRIPTION OF THE DRAWINGS
