A jet engine is provided which can efficiently pressurize fuel. A jet engineincludes a pumpthat heats fuel, a heating conduitthat heats the pressurized fuel, a fuel turbinethat provides mechanical power to the pump, and an electric rotating machine. When a given condition is not satisfied, the electric rotating machineprovides mechanical power to the fuel turbine. When the given condition is satisfied, the fuel that has passed through the heating conduitbefore combustion flows into the fuel turbineto provide mechanical power to the fuel turbine

Jet engine

A scramjet engine includes first and second flow path forming members and first and second fuel injection devices. A flow path formed between the first and second flow path forming members includes a turbulence forming region where compressed air is introduced and a combustion region located downstream thereof. The second flow path forming member is formed with a protrusion in the turbulence formation region. The first fuel injection device is configured to inject fuel into the compressed air via a first fuel nozzle. The second flow path forming member is formed with a cavity located in the combustion region. The second fuel injection device is configured to inject fuel into the compressed air via a second fuel nozzle. The cavity is provided with an inclined surface connected to a bottom surface. An inclination of the inclined surface is adjusted so that a shock wave is generated in the combustion region.
