Abstract
A roller traction drive system integral with a non-engine drive means and a clutch assembly in an aircraft drive wheel drive system capable of moving an aircraft autonomously on the ground is provided. The roller traction drive system is selectively activated by the clutch assembly into and out of actuating contact with the non-engine drive means to drive the aircraft drive wheel. Roller traction drive system components are made of materials designed to enable dry running and operation at the torques, drive means speeds, and reduction ratios required to actuate a drive means and drive a drive wheel for autonomous aircraft ground movement. Roller traction drive materials may be selected to maintain effective torque transfer between roller traction drive system components and the non-engine drive means as well as to minimize undesirable thermal expansion.
