PROBLEM TO BE SOLVED: To provide a turboprop type or turbofan type jet engine that can harmonize a characteristic associated with a relationship among an atmospheric velocity, driving force, and a rotational speed of a propeller or a fan with a characteristic associated with a relationship among an atmospheric velocity, driving force, and a rotational speed of a gas turbine.SOLUTION: In a turboprop type or turbofan type jet engine which has a gas turbine and a propeller or a fan rotationally driven by the gas turbine, a transmission is interposed between a rotary shaft of the gas turbine and the propeller or the fan. |
