Abstract:
The purpose of the present invention is to prevent generation of wingtip vortices and reduce induced drag. A fluid adjustment device (4) is provided with: a body part (7) mounted on a wing tip, which is an end part of a main wing (3) on the opposite side to the wing root, and having an upper opening and a lower opening formed in an upper surface of the body part and a lower surface of the body part; a first Francis turbine (8) that sucks air from the upper opening and the lower opening and discharges the sucked air from the trailing edge side of the main wing (3); and a first motor (9) for rotating the first Francis turbine (8) in a direction opposite to a rotation direction of a wingtip vortex generated at the wingtip. The first Francis turbine (8) has a central axis extending from the leading edge of the main wing (3) toward the trailing edge, sucks air from the circumferential direction, and discharges the sucked air in the axial direction.
