The invention relates to a lift force generating device which comprises a center shaft, a connecting part, an airflow restraining part and an airflow deflection part. Wherein the airflow restraining parts are installed on the inner side and the outer side of the airflow deflection part, and the center shaft is connected with the inner side of the airflow deflection part and/or the airflow restraining parts installed on the inner side of the airflow deflection part through the connecting parts. A positive mounting angle is formed between the airflow deflection part and a rotating plane formed when the airflow deflection part does circular motion around the center shaft, the distance from the front edge center to the rear edge center of the airflow deflection part is larger than the distance from the inner side center to the outer side center, and a wing-shaped section is arranged on a circular motion track line around the center shaft from the front edge to the rear edge. The plane projection shape of the airflow deflection part is a sector ring shape gradually approaching the central shaft from the front edge to the rear edge, a sector ring shape gradually converging from the rear edge or a traditional sector ring shape. Compared with a traditional rotor wing, the plane sweeping area during rotation can be greatly reduced, and the safety of an aircraft during take-off and landing can be obviously improved.

    本发明涉及一种升力产生装置,包括中心轴,连接部,气流约束部,气流偏转部;其中气流约束部安装在气流偏转部内侧和外侧,中心轴通过连接部与气流偏转部内侧和/或安装在气流偏转部内侧的气流约束部相连接;气流偏转部与绕中心轴做圆周运动时形成的旋转平面之间具有正安装角,气流偏转部前缘中心到后缘中心的距离大于内侧中心到外侧中心的距离,前缘到后缘在绕中心轴圆周运动轨迹线上具有翼型剖面,气流偏转部平面投影形状为由前缘到后缘逐渐向中心轴靠近的扇环形、后缘逐渐收敛的扇环形或传统扇环形。本发明与传统旋翼相比能大幅减小旋转时的平面扫掠面积,可明显提高飞行器起降时的安全性。
