Abstract:
1. A driving device for driving a wheel of an airplane in a direction same as that of a revolution of the wheel after landing, comprising a revolution drive disc including: a flat ring plate extending along a whole periphery of the wheel and having an attachment portion adapted to attach on a side surface of the wheel, the ring plate being formed from rubber-based material; and a plurality of fins formed from rubber-based material and arranged on the ring plate at a predetermined pitch in a peripheral direction of the ring plate, the plurality of fins being obliquely arranged on an outer side surface of the ring plate so that when the plurality of fins receives relative atmospheric air flow, a torque generated by a part of the plurality of fins at a lower side of the tire in the direction same as that of the revolution of the wheel after landing is larger than a torque generated by a part of the plurality of fins at an upper side of the tire in a direction reverse to that of the revolution of the wheel after landing, wherein the ring plate is arranged to attach to the side surface of the wheel so that the revolution drive disc deforms in accordance with a deformation of the tire.
