摘要： A disc wheel, particularly for rail vehicles, with a composite metal/plastic structure. In order to make possible simple manufacture with at the same time adequate force transmission, a structure between the hub and the tread comprises a plastic structure comprising two half shells of the same design which are subdivided in sector fashion by spoke-like reinforcement ribs. The reinforcement ribs each have a longitudinal slot into which rib plates are inserted which connect the two half shells to each other. Advantageously, plastic foam is inserted into the cavities of the half shells. All joints between the plastic structure and the hub or the tread are cemented joints.

摘要： The present rotor blade is constructed as a so-called monocoque or shell type blade for use in large fans and windmill rotors. For this purpose the blade is made of fiber reinforced synthetic material with a differnt orientation of the fibers in different sections of the blade. The transition between the blade proper and the connecting end of the blade is formed by a blade root section which has a connecting end of circular or elliptical cross-section and a wing facing end corresponding in cross-section to the blade cross-section. The blade root section has three zones. In the main leading edge zone including the leading edge and adjacent sides of the blade root section the reinforcing fibers extend in parallel to one another. The fibers also extend unidirectionally in a rear zone forming the trailing edge of the blade root section and in this trailing edge zone the fibers also extend in parallel to one another but at an angle relative to the fibers in the leading edge zone. An intermediate zone is located between the leading and trailing edge zones. The fibers in the intermediate zone are arranged in a cross-over relationship relative to one another. The connecting end is formed only by unidirectionally extending fibers.
