The invention relates to a turbopropeller engine reverse thrust system, and relates to the field of aero-engines. The system comprises an outer shell mechanism, an inner shell mechanism, a fan mechanism and a rotating shaft mechanism, and a first exchange hole capable of being opened and closed is formed at the front half portion of an outer shell; the inner shell mechanism comprises an inner shell and a connecting frame which are fixedly connected with each other; one end of the inner shell is fixed with the front half part of the outer shell mechanism; one end of the connecting frame is fixed with the rear half part of the outer shell mechanism; a second exchange hole which can be opened and closed is formed in the joint of the inner shell and the connecting frame; the fan mechanism comprises fan blades located in the inner shell; the rotating shaft mechanism comprises a rotating shaft for driving the fan blades to rotate and a base for supporting the rotating shaft, and an air outlet hole capable of being opened and closed is formed in the base; and according to the scheme, different from a traditional manner that speed reduction is achieved through a speed reduction gear, speed reduction of an aircraft is completed by opening and closing the corresponding first exchange hole, the corresponding second exchange hole and the corresponding air outlet hole, the structure of a whole engine is simpler, and the manufacturing cost of the engine is lower.

    一种涡轮螺旋桨发动机反推系统,涉及到航空发动机领域,包括外壳机构、内壳机构、风扇机构和转轴机构,外壳前半部上设置有可打开、可闭合的第一交换孔;内壳机构包括相互固定连接的内壳体和连接架;内壳体的一端与外壳机构的前半部固定;连接架的一端与外壳机构的后半部固定;内壳体与连接架的连接处设置有可打开、可闭合的第二交换孔;风扇机构包括位于内壳体内的扇叶;转轴机构包括用于驱动扇叶转动的转轴和支撑转轴的底座,底座上开设有可打开、可闭合的出风孔;本方案不同于传统的需要减速齿轮来实现减速,通过打开、关闭相应的第一交换孔、第二交换孔和出风孔就完成飞机的减速,使得整个发动机的结构更加的简单,其造价成本更低。
