Title
(EN) Horizontal axis rotor and boat equipped with said rotor
(ZH) 横轴旋翼以及具备横轴旋翼的舟艇
Abstract
(EN) The purpose of the present invention is to provide a horizontal axis rotor in which, rather than a fluid being pushed out by blades, a high-speed flow associated with a Coand effect resulting from the rotation of the blades flows toward the back face and a propulsive force is obtained as the counteraction, such that the horizontal axis rotor has a high rotational efficiency at a low power. A lift-type blade 1 is configured such that the front face 3D in the flow-receiving direction is a bulging face having the shape of a large arc in the chord direction and the back face 3E in the flow-releasing direction is smaller than the bulge of the front face 3D, such that a high-speed flow passing from the trailing edge 3G part in the back face 3E direction along the chord direction of the front face during rotation acts as a propulsive force.
(ZH) 本发明提供小动力且高旋转效率的横轴旋翼,不是由叶片将流体推出,而是使伴随利用叶片的旋转产生的康达效应的、高速流流向背面方向,通过反作用获得推进力。在升力型叶片(1)上,将受流方向的正面(3D)在弦方向设为大的弧状的鼓出面,并使放流方向的背面(3E)小于正面(3D)的鼓出,旋转时沿正面的弦方向、从后缘(3G)部通过背面(3E)方向的高速流成为推进力。
