The invention discloses a quantum pitch synchronous reverse propeller set. Two or more fixed-pitch propellers are arranged to form a propeller set. A horizontal common driving shaft is arranged; meanwhile, each fixed-pitch propeller is driven to rotate; the rotating speeds of the fixed-pitch propellers are the same; the distances between the rotating centers of every two adjacent fixed-pitch propellers are equal. The rotating directions of two adjacent fixed-pitch propellers are opposite; namely, two adjacent fixed-pitch propellers synchronously rotate reversely; the number of blades of each fixed-pitch propeller is the same; the diameter of the blades is the same, the screw pitches of the fixed-pitch propellers are arranged from large to small; when the first fixed-pitch propeller rotatesclockwise; the reaction torque of the quantum pitch synchronous reverse propeller set is equivalent to that of a fixed-pitch propeller which rotates clockwise; when the first fixed-pitch propeller rotates anticlockwise, the reaction torque of the quantum pitch synchronous reverse rotation propeller set is equivalent to that of the fixed-pitch propeller rotating anticlockwise, the quantum pitch synchronous reverse rotation propeller set is applied to a multi-shaft helicopter and replaces a single fixed-pitch propeller, the loading capacity and the wind resistance of a multi-shaft helicopter are improved, the efficiency is improved, and the number of engines is reduced.
一种量子螺距同步反转螺旋桨组,由两个或两个以定距螺旋桨排列组成一组螺旋桨组,设置一条水平公共驱动轴,同时驱动各个定距螺旋桨转动,各个定距螺旋桨的转速相同,相邻两个定距螺旋桨的旋转中心距离相等,相邻两个定距螺旋桨的转向相反,即相邻两个定距螺旋桨同步反转,各个定距螺旋桨的桨叶数量相同,桨叶直径相同,定距螺旋桨的螺距由大到小排列,第一定距螺旋桨顺时针转时,量子螺距同步反转螺旋桨组的反扭矩等效为顺时针转的定距螺旋桨,第一定距螺旋桨逆时针转时,量子螺距同步反转螺旋桨组的反扭矩等效为逆时针转的定距螺旋桨,应用于多轴直升机,替代单个定距螺旋桨,提高多轴直升机的载重能力和抗风能力,提高效率,减少发动机的数量。
