The invention belongs to the technical field of propeller propulsion, and particularly relates to a vertical type rotary paddle for a helicopter with toppling and rotating wings. A vertical type rotary paddle for a helicopter with toppling and rotating wings comprises a fairing and two or more paddle supports, the paddle supports are connected with a rotating shaft, the paddle supports and the rotating shaft are located in the fairing, the rotating shaft can drive the paddle supports to rotate, a plurality of vertical type paddles are installed on the paddle supports and arranged in rows, and space distances are reserved between the vertical type paddles. The vertical paddle and the rotating shaft form an included angle of 45 degrees, the vertical paddle comprises a paddle main body, and the lower part of the paddle main body is provided with an elliptical channel. The device can be used for the toppling wing helicopter, can fly in severe weather and alternating airflow, cannot cause stall to cause air crash, is slightly influenced by the alternating airflow and is high in safety, and the cruising speed can be increased by more than one time.

    本发明属于螺旋桨推进技术领域,具体涉及一种傾转翼直升机用立式旋划桨。傾转翼直升机用立式旋划桨,包括整流罩和2个或两个以上的桨叶支架,桨叶支架连接旋转轴,桨叶支架和旋转轴位于整流罩内,旋转轴可带动桨叶支架旋转,桨叶支架上安装若干立式桨叶,立式桨叶呈排设置,立式桨叶之间留有空间距离,立式桨叶与旋转轴呈45°夹角,立式桨叶包括桨叶主体,桨叶主体下部设置椭圆通道。本发明可用于傾转翼直升机、在恶劣天气、交变气流中飞行、不会造成失速发生空难,受交变气流影响很小,安全性强,巡航速度可增加1倍以上。
