Abstract

The invention discloses a hydrocarbon fuel internal reforming fuel cell and gas turbine combined power generation system for an airplane, and belongs to the field of airplane power generation systems. According to the system, on the condition that the flexibility of the airplane is met, a hydrocarbon fuel cell is applied to supply power to the system, and the efficiency of the system is improved by adopting the mode of combining the hydrocarbon fuel cell with a gas turbine; hydrocarbon fuel is high in volume energy density and low in storage and heat exchange quality penalty; waste heat of tail gas is fully utilized, fuel which is not utilized by the solid oxide fuel cell is fully utilized to be burned in a burning chamber, the hydrocarbon fuel provides a high-temperature high-pressure working medium for a turbine after being burned, the turbine does work to generate power, the power serves as electric power for the airplane, and then the fuel utilization rate is greatly increased.

Description

technical field [0001] The invention belongs to the field of aircraft power generation systems; in particular, it relates to a hydrocarbon fuel internal reforming fuel cell gas turbine combined power generation system for aircraft. Background technique [0002] With the increase in the demand for the flight time of aircraft and the flexibility of ensuring the travel tasks of aircraft, the use of ultra-long-duration high-altitude unmanned aircraft has received more and more attention. All major aviation countries in the world have put forward corresponding plans. Aircraft power demand has become a bottleneck restricting the development of aircraft. How to improve the power generation efficiency of the aircraft power generation system while keeping the airframe compact has become a research hotspot.
