Title:
AUTOMATIC ANGLE-OF-ATTACK CONTROL WING AND AIRCRAFT AND VESSELS COMPRISING AUTOMATIC ANGLE-OF-ATTACK CONTROL WING
Document Type and Number:
WIPO Patent Application WO/2018/131821
Kind Code:
A1
Abstract:
The present invention provides an automatic angle-of-attack control wing that always maintains a reference angle of attack with optimum efficiency by automatically controlling the angle of attack of a wing according to changes in the direction of a fluid flow. The present invention comprises an angle-of-attack control shaft that serves as a reference for the rotation of a wing under a specific point of the wing, such that when the angle of attack of the wing is changed from a reference angle of attack due to a change in a fluid flow direction, the wing is automatically rotated based on the angle-of-attack control shaft to automatically return to the reference angle of attack. Due to this feature, since the angle of attack of the wing can be maintained at optimum efficiency at all times, the effect of utilizing aerodynamic force is significantly increased, the present invention can be applied to all devices that are actuated by generating lift or thrust by means of a wing or a propeller, and the efficiency of such devices is enhanced.
