Abstract
A landing wheel assembly for a rotorcraft having a light on gear phase during takeoff and landing includes a tire and an anti-roll oscillation rim. The tire has first and second side walls and forms a center aperture. The anti-roll oscillation rim includes a center disc disposed in the aperture of the tire, a first side wall support plate protruding from the center disc and extending at least 25 percent of the vertical length of the first side wall of the tire and a second side wall support plate protruding from the center disc and extending at least 25 percent of the vertical length of the second side wall of the tire. The first and second side wall support plates support the first and second side walls, respectively, to stiffen the tire in the light on gear phase of takeoff and landing, thereby reducing roll oscillations of the rotorcraft.
