The invention belongs to the technical field of aviation aircrafts, and particularly relates to a hydrogen energy power aircraft. The invention provides a hydrogen energy power aircraft. The hydrogen energy power aircraft comprises an aircraft body, a turbine engine, a fuel storage part and a heat exchange part which are of an integrated structure. The fuel storage part and the heat exchange part are arranged at the middle part and wings of the aircraft main body; the turbine engine is arranged below the wings of the aircraft main body; the heat exchange part comprises a first-stage heat exchanger and a second-stage heat exchanger, and in the first-stage heat exchanger, cold hydrogen exchanges heat with high-temperature residual gas of an engine and is used for increasing the temperature of the cold hydrogen; and in the second-stage heat exchanger, cold hydrogen exchanges heat with bleed air of the air compressor and is used for reducing the bleed air temperature. In the technical scheme provided by the invention, a liquid hydrogen fuel tank hydrogen supply system is combined, and the aircraft body size, engine circulation parameters and heat exchange system parameters are designed and adjusted, so that the wing body fusion layout aircraft with high lift-drag ratio and relatively large internal capacity is prepared.
