Abstract
The invention relates to a composite wheel capable of withstanding large centrifugal forces, including at least two elements made of materials with different yield strengths, one of said elements being peripheral and the other element connecting said peripheral element to the wheel hub, characterized in that said element connecting the peripheral element to the hub comprises two conical flanges having their concave sides facing each other, means being provided to vary the angle subtended by the flanges whereby to obtain, as necessary, either a limitation of the stresses exerted on the material forming the flanges (the diameter of the wheel remaining constant and the angle between flanges widening), or an accompaniment by said flanges of the expansion undergone by the peripheral material (the wheel diameter increasing and the inter-flange angle widening or narrowing). A composite wheel according to this invention may be used with advantage but by no means exclusively as a test wheel for an eddy-current machine, a linear motor, a brake, or magnets for providing magnetic lift. Alternatively, it may be used as a high energy storage wheel for a variety of vehicles.
