Problems solved by technology

[0002] At present, aircraft engines are powered by conventional fuels, which are increasingly in short supply and cause air pollution
The calorific value per unit mass of conventional fuel is limited, and the carrying of fuel causes a substantial increase in the take-off weight of the aircraft. The "green variable aero-engine" with the patent number 97235783.1 in the existing technology proposes to provide power with an engine of a sustainable power generation device to reduce environmental pollution

Abstract

A liquefied hydrogen fuel carrying and heat exchanging system for high-speed airplane using hydrogen as fuel is composed of master liquefied hydrogen tank, the liquefied hydrogen tanks hidden in wings, the liquefied hydrogen tanks hidden in main body, cut-off valves, liquefied trunk, two evaporators, combustion chamber of engine, hydraulic oil heat exchanger, lubricating oil heat exchanger, hydraulic system, fans and lubricating system. It features that the cold of liquefied hydrogen is transferred to hydraulic system and lubricating system.

Description

technical field [0001] The invention relates to a liquid hydrogen fuel carrying and heat exchange system, in particular to a liquid hydrogen fuel carrying and heat exchange system for a hydrogen-burning high-speed aircraft, and belongs to the technical field of aircraft. Background technique [0002] At present, aircraft engines are powered by conventional fuels, which are increasingly in short supply and cause air pollution. The calorific value per unit mass of conventional fuel is limited, and the carrying of fuel causes a substantial increase in the take-off weight of the aircraft. The "green variable aero-engine" with the patent number 97235783.1 in the existing technology proposes to provide power with an engine of a sustainable power generation device to reduce environmental pollution. pollution, but because there is no high-power, non-polluting portable power source to promote the aero-engine at present, the scheme cannot be put into practice. The use of hydrogen fue...
