The invention relates to a wire magazine _ for mediated by a stationary control device ' Electric wire guided missiles that are in flight from one or more of these Unwind wire magazines inside the missile, which consists of a housing with a funnel-shaped Outlet part through which the wire is drawn out and consists of a spool on which the wire is wound is and which is arranged in the housing that the wire over her one end in Direction of the axis of the bobbin is unwound. Such wire magazines are known.

The speed at which the wire is unwound is extraordinarily great; correspondingly large is the risk of tearing. The object underlying the invention is to reduce the Danger of tearing.

Surprisingly, it has been found that the risk of tearing is reduced when according to the invention a coaxial guide element is provided for the wire, the inner diameter of which is smaller as the diameter of the spool at the end of the spool over which the wire is unwound, and which consists of a ring fastened in the funnel-shaped outlet part.

Rings as guide elements for the unwound wire are known, but they are exclusive Guide element instead of the funnel-shaped outlet part required in the invention. One Such guidance solely by rings is only useful for lower unwinding speeds, since the The risk of tearing is even greater than with the magazines to be improved according to the invention funnel-shaped outlet part.

The invention is described in more detail below with reference to the drawing, whose

F i g. 1 a wire magazine in longitudinal section and its

Figure 2 shows a perspective view of the airborne missile showing the arrangement of the wire magazines is illustrated in the missile.

From Fig. 1 it can be seen that the wire magazine consists of a cylindrical housing 1, which is on one end is closed by an end wall 2 and at the other end a funnel-shaped outlet part 3 has an outlet tube 4 which is slightly inclined with respect to the magazine axis. In the housing 1 is a Spool 5 arranged coaxially with the housing on which the wire is wound, its End passed through the funnel-shaped outlet part 3 and the outlet pipe 4 and with the stationary Equipment connected from the flight wire magazine for missiles

body is started and with their control units the wire should form the connection. The connection with the electrical steering devices inside the missile is by electrical Connecting parts 7 made in the wire magazine. At the inner end of the magazine are mechanical Devices shown which trigger certain functions during the flight of the missile should serve when a predetermined length of the wire is unwound. These facilities have has no relation to the present invention and therefore need not be described in detail will.

In the case of the one shown in FIG. 2 are shown in the middle part of the missile 10 near his

Shell housed two wire magazines, the outlet pipes 4 on its outer circumference to open.

During the flight of the missile, the wire, which with its free end - as mentioned - is attached to the stationary launch devices to transmit control signals to the missile can, unwound from each bobbin 5 over the end of the coil 8, the funnel-shaped Outlet part 3 faces. The wire has a very small diameter (for example by 0.2 mm) and is unwound at high speed, where-

due to the risk of tearing. In accordance with the present invention, however, it has been found that the risk of tearing is significantly reduced if in the funnel-shaped outlet part 3 a coaxial Guide element 9, for example a ring, is used, the inner diameter of which is mine than that of the coil end 8, so that the wire is forced to make its way with a larger one Take the angle inwards towards the magazine axis than the straight connection from the coil circumference corresponds to the outlet pipe 4 out. It has not been fully understood how the ring reduces the possibility of wire breakage. It should be noted, however, that the wire 6 is provided with an electrically insulating coating, the is partially rubbed off during its movement, creating dust. It can be presumed that the ring by the formation of the collecting space at 11 for this dust prevents this from disturb the wire movement. A particular embodiment of the invention has been described and illustrated, however each part can produce a similar effect, which is similar to the wire to a Forces path closer to the magazine axis than that of the outlet and spool only during trajectory determined by its rotation. - - ■ '■ "' claim: Wire magazine for controlled by a stationary control unit by means of electrical wires Missiles that are in flight from one or more of these wire magazines unwind inside the missile, which consists of a housing with a funnel-shaped outlet part, through which the wire is pulled out, and consists of a spool on which the wire is wound is and which is arranged in the housing that the wire over her one end in Direction of the axis of the reel is unwound, characterized in that in known Way, a coaxial guide element (9) for the wire (6) is provided, the inner Diameter is smaller than the diameter of the bobbin (5) at the coil end (8), about that the wire is unwound and that from a fixed in the funnel-shaped outlet part (3) Ring is made.
