Abstract: A rail vehicle body consisting of a support frame and sandwich parts attached thereto having an outer and an inner cover layer and supporting layer glued in between them, comprises, with a view to cost-effective fabrication and above all reduction of assembly cost, individually made body modules which are designed in integral construction as a sandwich structure with support frame parts inserted in the region of the supporting layer and fastened to the cover layers and being provided at the edges of the support frame parts with fitting connections for assembly of the body modules.

Abstract: A system for the automatic manufacture of pipe-shaped or tubular structural parts of a fiber-reinforced plastic. A device is provided with which fiber strands are soaked with a heat-hardenable binding agent. The device has the capability of clamping at least one winding mandrel into a winding machine, on which mandrel can be placed the soaked fiber strands. The winding machine has a guiding mechanism for the fiber strand which is to be wound onto the mandrel, which guiding mechanism can be moved back and forth parallel with respect to the mandrel. A transporting mechanism is provided for moving the wound structural parts through a hardening furnace to a device for extracting the winding mandrels from the hardened structural parts and to at least one finish-working station. The extracted and now empty winding mandrels are returned through a mandrel preparation station to the winding station. The finish-working station is provided between the hardening furnace and the mandrel extracting device.

Abstract: Crash or shock absorbing structural components made of fiber reinforced shetic materials and having portions of different diameters including at least one portion of a larger diameter than another portion, are produced by winding synthetic fibers onto a winding arbor (6) in a desired winding pattern. For this purpose a winding support cage (14) is arranged on the winding arbor (6). The winding support cage (14) has circumferential end edges provided with cut-outs (18, 18') for receiving fiber strands. Arresting pins (25, 26) reach into pairs of these cut-outs for temporarily holding the winding support cage (14) against rotation with the winding arbor when a fiber guide (12) moves into a respective starting position for the next winding operation.

Abstract: A rotor blade formed of a fiber-reinforced plastic material is constructed for the absorption of at least one of longitudinal forces and bending forces. The interior of the blade is formed of an elongated bundle of fiber strands forming a loop intermediate its ends. The loop defines one end of the longitudinally extending blade. The bundle has two limb portions extending from the loop and forming, adjacent the loop, a transition portion followed by a neck portion and then a blade portion. A skin encloses the blade outwardly from the loop. A layer of fiber strands extends around the outer surface of the loop and between the skin and the limb portions at least in the transition portion. In the region of the loop the fiber strands extend in parallel relation with the fiber strands in the bundle, however, in the transition portion the fiber strands in the layer extend angularly across the longitudinal axis of the blade.

Abstract: A rotor blade has a neck section which connects the blade proper to a rotor ead at the blade root. The neck section is flexible against bending in the lead-lag direction and in the flapping direction. A carrier member is located alongside or inside the neck section but spaced from the neck section. The carrier member is resistant against bending at least in the lead-lag direction or in the flapping direction. The carrier member is rigidly connected at its one end to the blade proper. A layer of a damping material is operatively interposed between the carrier member and the neck section, preferably at the blade root end of the neck section, whereby blade vibrations preferably in the lead-lag direction are damped and substantially prevented from entering into the rotor head.
