ABSTRACT:
An assembly for mounting a propeller, which is driven by an aircraft engine, on a longitudinal member of a lightweight aircraft. The assembly includes a sleeve positioned about the longitudinal member, and a pair of opposed adjustable cups securing the sleeve at its ends longitudinally relative to the longitudinal member. A rotating mechanism mounted to the propeller, rotatable about the sleeve, and driven by the aircraft engine rotates the propeller concentrically about a longitudinal axis of the longitudinal member. Suitable bearings are disposed between the rotating mechanism and the sleeve and the rotating mechanism rotates on these bearings. Vibration dampening rings are placed between the cups and the sleeve and dampen the vibration transmitted between the rotating mechanism and the longitudinal member.
