Novel micro-miniature turboprop jet engine

The invention relates to a novel micro-miniature turboprop jet engine. The novel micro-miniature turboprop jet engine is formed by replacing a fuel gas generator assembly in a turboprop jet engine with a turbojet engine as a core engine and remanufacturing. The novel micro-miniature turboprop jet engine is composed of a furl gas generator assembly (1), a power turbine and exhaust assembly (2), a reducer assembly (3) and a propeller (4). The front end of the reducer assembly (3) is connected with the power turbine and exhaust assembly (2), and an output shaft (33) is connected with the propeller (4). The novel micro-miniature turboprop jet engine creates a new path for the micro-miniaturization of a turboprop engine, and broadens the scope of use of the micro-miniature turboprop engine. 本发明涉及种新型微小型涡桨喷气发动机，它是由涡轮喷气式发动机为核心机取代了涡桨喷气发动机中的燃气发生器组件改制而成；它由燃气发生器组件(1)、动力涡轮与排气组件(2)、减速器组件(3)、螺旋桨(4)组成；减速器组件(3)前端与动力涡轮与排气组件(2)连接，输出轴(33)连接螺旋桨(4)；本发明为涡桨发动机的微小型化创设条新路径；本发明拓宽了的微小型涡桨发动机使用范围。
