Abstract
An electric taxi system (ETS) for an aircraft includes rollers attached circumferentially to a wheel of the aircraft, and a sprocket with circumferentially distributed teeth attached to a sprocket-tooth ring. The sprocket has a hub with an axis of rotation that is parallel to an axis of rotation of the wheel of the aircraft. The sprocket includes a flexible member interposed between the hub and the sprocket-tooth ring. A radial axis of at least one tooth of the sprocket is substantially perpendicular with an axis of rotation of at least one of the rollers even if the at least one of the rollers is non-parallel to the axis of rotation of the wheel of the aircraft.
