Wing with automatically adjusted angle of attack and aircraft and ship having the same

摘要

Provided is an automatic attack angle-adjustable wing, in which the attack angle of the wing is automatically changed in accordance with a change in the flowing direction of fluid to always maintain optimal efficiency. According to the present invention, the automatic attack angle-adjustable wing has an attack angle adjustment shaft installed at a predetermined position on the lower side of the wing to be used as the rotational center of the wing, such that the wing is automatically rotated with respect to the attack angle adjustment shaft when the attack angle of the wing is different from the reference attack angle by the change in the flowing direction of fluid to be returned to the reference attack angle. Due to such configuration, the attack angle of the wing can be always maintained in an optimal state, thereby increasing an effect of using the force of air. Moreover, provided are effects of being applied to all apparatuses operated by generating lift or thrust with a wing or a propeller, and increasing the efficiency of such apparatuses.
