The invention belongs to the technical field of aircraft power, and relates to an energy transfer supply system of a hydrogen-powered aircraft and a control method. A part of liquid hydrogen in a liquid hydrogen storage tank enters electronic equipment, hydraulic oil and a lubricating oil heat exchanger absorb waste heat of the equipment on the machine and then are gasified, pressurized by a hydrogen circulating pump and fed into a fuel cell for heat management, and then fed into the fuel cell for power generation after further heat absorption and temperature rise; and the other part is fed into a hydrogen fuel engine and enters an engine combustion chamber for combustion after absorbing heat of turbine blades of the engine. The system can fully utilize the heat sink of the liquid hydrogen while conveying and supplying the liquid hydrogen from the low-temperature storage tank to the hydrogen fuel cell/hydrogen fuel engine for efficient utilization, and has the advantages of high flexibility and strong adjusting capability.
本发明属于飞行器动力技术领域,涉及一种氢动力飞机的能源转输供给系统及控制方法。液氢储罐的液氢一部分进入电子设备、液压油和滑油热交换器吸收机上设备废热后气化,经氢气循环泵增压送入燃料电池热管理,进一步吸热升温后送入燃料电池发电;另一部分送入氢燃料发动机,吸收发动机涡轮叶片热量后进入发动机燃烧室燃烧。本系统在输送供给液氢从低温储罐到氢燃料电池/氢燃料发动机高效利用的同时,可充分利用液氢的热沉,具有灵活度高、调节能力强的优点。
