PROBLEM TO BE SOLVED: To solve a problem that a conventional jet engine throws away a high heat generated by combustion and is therefore less efficient. SOLUTION: A plurality of water injection nozzles are provided on an outside of a turbine behind a combustion chamber of the jet engine. A temperature sensor is installed on a rear part of a gas discharge opening. A water tank is provided and the water injection nozzles are forcedly fed therefrom by a high pressure pump. Water injection is carried out when temperature of the rear part of the gas discharge opening detected by the temperature sensor on the rear part of the gas discharge opening becomes equal to or beyond a certain value. A water injection quantity of water is set at a value which can be gasified and is proportioned to a rotation speed of the turbine. When the temperature of the rear part of the gas discharge opening detected by the temperature sensor becomes equal to or less than the certain value, the water injection is stopped and when the temperature rises equally to or beyond the certain value again, the injection is carried out again. The engine is equipped with all necessary things. COPYRIGHT: (C)2006,JPO&NCIPI
