The invention relates to an improved connecting structure of an aero-engine and a propeller, and belongs to the technical field of aerospace equipment, the improved connecting structure comprises the aero-engine, the propeller and a lengthened shaft sleeve, and the two ends of the lengthened shaft sleeve are fixed to an output shaft of the aero-engine and the propeller through connecting pieces respectively. The design constraint of a traditional connecting structure of the aero-engine and the propeller is broken through, the lengthened shaft sleeve is creatively additionally arranged between the aero-engine and the propeller, the distance between an output shaft of the aero-engine and the propeller is increased, interference between the propeller and the rear edge of the wing is avoided, and the gravity center of the aero-engine is closer to the lift center; and the flexibility and maneuverability of aerial operation of the aircraft are improved.
本发明涉及一种改进型航空发动机与螺旋桨的连接构型,属于航空航天设备技术领域,包括:航空发动机、螺旋桨及加长轴套,加长轴套的两端分别通过连接件固定在航空发动机的输出轴上和螺旋桨上。本发明突破传统航空发动机与螺旋桨连接结构的设计束缚,创造性地在航空发动机与螺旋桨之间加装加长轴套,拉大航空发动机输出轴与螺旋桨之间的距离,避免螺旋桨与机翼后缘干涉,使得航空发动机重心更靠近升力中心,增加飞机空中操作的灵活性和机动性。
