Abstract

PURPOSE:To generate the turning motion with torque from rotary blades and enable electric power to be generated, by mounting the rotary blades, having the section of an airfoil generating a lift in a flow of fluid, to a shaft. CONSTITUTION:If lift blades 2-1-2-8, mounted to a turning shaft 1 respectively by struts 3-1-3-8 and having a section of shape as shown in the drawing and an attack angle being alpha with respect to a plane X-X at a right angle with the center shaft 0, are placed in fluid flowing in the direction of V, the blades are turned around the turning shaft 1 serving as the center. Further a lift L is shown by the expression, L=CLX1/2rhoV<2>XS, where CL=lift coefficient, rho=fluid density, V=velocity and S=area. Accordingly, if a generator is connected to the turning shaft 1 through a speed changer, the lift generated in the lift blade and a turning effect resulting from this lift can move the generator to produce electric power.

向の揚力を生じることは良く知られている。The one in Figure 1 is generally known as the cross-sectional shape of an airplane wing. When air flows from B towards the cross-sectional molding of the blade as shown by the arrow, a speed difference occurs between the air flow C on the upper surface and the air flow D on the lower surface, and the pressure on the upper surface C side where the speed is faster is D. It is well known that the airfoil A produces an upward lift force due to the side pressure drop.

を動かずことができる。即ち発電することができる。Therefore, if a generator is connected to this rotating shaft via a transmission, the generator can be kept stationary due to the lifting force generated in the lifting plate and the accompanying rotational force. In other words, it is possible to generate electricity.

この揚力板は更に高揚力装置と組合せればより効果的に
動力を得ることができる。This lifting plate can be combined with a high lift device to obtain power more effectively.
