Abstract
A cylindrical rotating body (1) of low inertia is provided including a cylindrical body (1) having a large length/diameter ratio. The cylindrical body (1) is of thin wall thickness and is sealed at the opposite ends by sealing means (3, 8). The hollow interior (9) of the cylindrical body (1) is loaded with a pressurized medium (10).
Claims13
A cylindrical rotating body of low inertia comprising:
- a hollow cylindrical body defining a web contacting outer surface, the hollow body consisting of a thin layer of a first composite material, wherein the composite material includes fibrous material embedded in a bonding resin, the fibrous material including pretensioned longitudinal fibers to increase a bending stiffness of the hollow cylindrical body;
- a pair of end caps permanently mounted to the hollow body for sealing the hollow interior of the cylindrical body;
- and
- a pressurized medium loaded within the cylindrical body.
