Abstract: An arrangement for force-free retention of a bearing system having an axis of rotation comprises a cylindrical hollow axle for concentrically receiving and holding the bearing system. By way of a hold-down and release mechanism, a bearing shell can be fastened to the hollow axle in such a manner that, when the bearing system is not acted upon by a load, all lateral and axial forces applied to the arrangement can be transmitted via the cylindrical hollow axle into axle receiving devices.

Abstract: A load disconnection lock having a locking device which is secured against unlocking by means of a safety device as long as the tensile load is not less than a predefined minimum value, and which unlocks automatically when the tensile load is less than the predefined minimum value. A second safety device is provided for the locking device and has a fluid-filled housing in which a piston is guided. The piston has a tensile load applied to it and has a hole as a flow channel for the fluid, such that the fluid can be exchanged between two housing subareas on both sides of the piston. The piston is connected to an activation slide which releases the locking device as soon as the piston has moved through a predetermined distance.

Abstract: A deployable antenna reflector comprising a central dish and a plurality of deployable sheet-like panels arranged around the central dish. The reflector further comprises a central supporting body, whereon the central dish is fixedly mounted and whereto the deployable sheet-like panels are hinged. The rotation axes of the individual deployable sheet-like panels are tilted with respect to the center point of the central dish. In the stowed configuration of the reflector, the deployable sheet-like panels are at least partially deflected in order to minimize the envelope of the reflector and that the panels relax upon deployment.

Abstract: The invention relates to a tow body for representing flying targets, having an infrared flare (3) situated at the rear of the tow body, the infrared flares being ejectable from the tow body and being pulled by the tow body by means of a reel-off towing cable during the burning time of the infrared flare.

Abstract: Trailing cable winch and method of operation in which an axially stationary, rotating winding arm is disposed in a carrier tube and driven by a motor arranged in the carrier tube. The trailing cable winch is operable to deposit a trailing cable on an axially reversibly movable cable drum which is disposed on the carrier tube. The rotation of the winding arm is synchronized with the advancing of the cable drum, so that, during a linear movement of the cable drum, the advance per rotation of the winding arm corresponds exactly to the diameter of the trailing cable. In the end position of the cable drum, two cable layers are deposited above one another.

Abstract: The invention relates to a tow body for representing a flying target by means of infrared flares, the infrared flares being situated on the rear of the tow body and being ejectable by the tow body and being pulled by the tow body by means of a reel-off towing cable during burning time. According to the invention, a drop unit (1) for the burned-up IR flares is arranged on the rear of the tow body, which drop unit (1) comprises a circular receiving unit (7) which is rotatably disposed and constructed under a retaining plate (8), for the towing cable nipples (17) forming the tow-body-side end of the towing cable, after the burning-up of an infrared flare, the corresponding towing cable nipple (17) connected with the infrared flare being released by a rotation of the receiving unit (7).

Abstract: The invention relates to a tow body for the representation of flying targets by means of infrared flares, the infrared flares being situated at the rear of the tow body and being ejectable from the tow body and capable of being pulled by the tow body by means of towing cables during the burning time. According to the invention, a section of the towing cable (6) situated between the IR-flare-side cable linkage (2) and the tow-body-side cable linkage (5) is sewn onto a woven flap (1), this connection being releasable during the reel-off operation of the towing cable (6).

Abstract: In a towed body with infrared flares located at its rear, the flares are in an ejection unit and are pulled out of the towed body via a tow cable as they ignite, preventing the towed body from being destroyed by missiles when it is used during target simulation.
