Patent number: 10597147Abstract: An aircraft tire includes a tire body forming an outer peripheral part of an aircraft wheel; and a protrusion with a pressure receiving surface configured to receive flight wind pressure toward one end and a streamline shape tapering toward another end. The protrusion rotates the aircraft wheel before touchdown through flight wind pressure received by the pressure receiving surface. The protrusion includes a pair of legs; a weight portion with a center of gravity positioned outwardly of respective horizontal positions of the pair of legs with respect to a center line widthwise of the tire body; and a hollow part extending between the ends of the protrusion. Centrifugal force that acts on the weight portion causes the pair of legs to fall over in a direction toward an outer periphery of the tire body to narrow the hollow part for reduction of an area of the pressure receiving surface.Type: GrantFiled: July 21, 2017Date of Patent: March 24, 2020Assignee: DAITO PRESS MFG. CO., LTD.Inventor: Takashi Yoshida

Patent number: 9731817Abstract: An aircraft tire capable of suppressing rubber tire wear during landing and shocks which accelerate or decelerate an aircraft at touchdown includes, on a side of a tire body constituting an outer peripheral part of an aircraft wheel, a protrusion for receiving flight wind pressure. The wheel is rotated ahead of the touchdown by the action of the wind pressure received by the protrusion in a direction in which the wheel rotates during a landing roll. Weight is inserted into a hollow part of the protrusion. Through use of centrifugal force on the weight in association with a rotational motion of the wheel, the protrusion is deformed to change its wind pressure receiving area for bringing rotational speed of the wheel ahead of the touchdown close to a rotating speed of the wheel that is consistent with a flying speed of the aircraft making the touchdown.Type: GrantFiled: July 28, 2015Date of Patent: August 15, 2017Assignee: DAITO PRESS MFG.
