Abstract: Relative rotation between an inboard and an outboard wheel component of an aircraft wheel assembly is inhibited by an interlocking tongue and groove interface. In one example, an aircraft wheel includes a first annular component, a second annular component separable from the first annular component, and at least one tongue and groove interface between the first component and the second component. The second annular component is connected to and aligned with the first component about an axis of rotation of the wheel. The at least one tongue and groove interface is configured to inhibit relative rotation between the first component and the second component about the axis of rotation of the wheel.

Abstract: An aircraft brake assembly (10) includes a plurality of spaced carbon stators (14), one of the stators (14) being a carbon pressure plate (22), a plurality of carbon rotors (18) extending into spaces between the plurality of spaced carbon stators (14) and forming with the stators (14) a brake stack, at least one piston (20) mounted adjacent the brake stack for driving the carbon pressure plate (22) into contact with one of the plurality of carbon rotors (18), and a metal pressure plate (36) mounted between the carbon pressure plate (22) and the at least one piston (20). Also a method of braking an aircraft using such an assembly (10).
