ANTI-ICE DEVICE, WING, AIRCRAFT, AND ANTI-ICE METHOD

摘要

The purpose of the present invention is to provide an anti-ice device, a wing, an aircraft, and an anti-ice method which prevent, with a simple structure, icing on the aircraft which flies in a flying environment under an icing condition. The anti-ice device according to the present invention outputs pressure waves to water drops that float in air in a supercooled state which exists in a traveling direction of the aircraft (10) to change the water drops into ice by the pressure waves. The pressure waves have 0.9 to 3.3 [Pa] on a predetermined position in consideration of attenuation in the case where an acceleration of, for example, 10 G is given to the water drops.
