The invention relates to a liquid hydrogen power aircraft, comprising: a liquid hydrogen storage system comprising a liquid hydrogen storage tank for storing liquid hydrogen, a liquid hydrogen pump arranged in the liquid hydrogen storage tank and used for conveying the liquid hydrogen to a liquid hydrogen vaporization device; the liquid hydrogen vaporization device is used for converting liquid hydrogen into normal-temperature high-pressure hydrogen; the fuel conveying and control system is used for conveying the normal-temperature high-pressure hydrogen to the combustion system; the combustion system comprises an engine which is provided with a combustion chamber, and combustion of hydrogen is conducted in the combustion chamber to generate thrust; heat generated during combustion is obtained through an air entraining pipe or an exhaust nozzle to serve as a heat source of the liquid hydrogen vaporization device; and under the action of the heat source, the liquid hydrogen is vaporized after passing through the liquid hydrogen vaporizing device and reaches a combustible state. The liquid hydrogen power system can be used for an aircraft in which liquid hydrogen fuel generates power through combustion, the number of needed devices is small, the overall weight of the liquid hydrogen power system is low, and the reliability of the overall framework of the liquid hydrogen power system is improved.

    本发明涉及一种液氢动力飞行器,包括:液氢储存系统,包括用于存储液氢的液氢储罐,在液氢储罐内布置有液氢泵,液氢泵用于将液氢输送至液氢汽化装置;液氢汽化装置,用于将液态氢转化为常温高压氢气;燃料输送与控制系统,用于将常温高压氢气输送至燃烧系统;燃烧系统包括发动机,其具有燃烧室,在燃烧室内进行氢气的燃烧,产生推力;通过引气或尾喷管获取燃烧时产生的热量做为液氢汽化装置的热源;在热源的作用下,液氢经过液氢汽化装置后汽化并达到可燃烧状态。本发明,可用于液态氢燃料通过燃烧产生动力的飞行器,所需设备少,液氢动力系统整体重量低,提高液氢动力系统整体架构的可靠性。
