Description

Device for introducing tail projectiles into the tube of a Launching device The invention relates to a device for introducing of stabilizer floors provided with approximately tangentially protruding over-caliber guide surfaces into the barrel of a launcher.

For stabilization in flight, rockets or long projectiles are on the rear End equipped with guide surfaces. To have a good effect in flight, you must these areas protrude beyond the largest diameter of the floor. The introduction Such a projectile into the launch tube therefore presents certain difficulties. For this purpose, in known designs, the guide surfaces are, for example Folded down towards the tip of the projectile, so that the guide surfaces are not in this state protrude beyond the largest bullet diameter. Easily insert around such projectiles to be able to, it is already known to funnel or at the launcher to attach funnel-shaped baskets. The guide surfaces are also known before inserting the projectile into the barrel to roll around the tail boom. For this So far, rings or sleeves were used, which are slipped over the tail unit and place the individual guide surfaces on the tail girder. These rings or sleeves are either already when inserting the projectile into the barrel or when firing stripped so that the guide surfaces can unfold when leaving the pipe. However, the latter known charging method always requires an additional part, namely the ring or the sleeve, as well as a corresponding preparatory step in which the ring is pushed over the rolled tail unit. In addition, tired when stored the material of the guide surfaces exposed to permanent bending stress.

In contrast, the invention provides at the pipe mouth or at the end of the pipe to provide an insertion aid device known per se for the launching device, which, when inserting the projectile into the tube, creates or winds up the causes over-caliber tangentially protruding tail surfaces on the tail girders. There is no need to prepare the projectile before inserting it into the launch tube, d. In other words, the bullets retain their normal shape with protruding protrusions until they are inserted into the tube Baffles, which ensures that they are also after the launch, i. H. unfold fully and evenly after leaving the tube.

Further features of the invention emerge from the following description Embodiments shown in the drawings.

In the figures, FIG. 1 shows a sectional view of an embodiment according to the invention, FIG. 2 is a plan view of the device according to FIG. Fig. 3 another embodiment of the invention, Fig. 4 is a plan view of the device according to Fig. 3, Fig. 5 to 7 further embodiments of the invention.

As can be seen in FIGS. 1 and 2, the end of the expands Launch tube 1 funnel-shaped. The pipe mouth or can be used as the pipe end the rear end of the pipe should be meant. The projectile is, as further indicated is, in the usual way - with muzzle-loaders from the front and with rear-loaders from the rear - Attached to the end of the pipe, the guide surfaces 3 of the projectile with their the Inclined edges 4 adapted to the inclination of the funnel lie against the wall 2 of the funnel. With further axial pressure and the associated pushing of the bullet into the As a result, tube 1 transmits a torque to the projectile or the tail unit carrier, so that the projectile can be inserted into the barrel while turning in a helical manner can, wherein the guide surfaces 3 wrap around the tail girder. Are the Baffles completely, the projectile can easily move up to the firing position the tube 1 can be inserted.

In the embodiment according to FIGS. 3 and 4, the charging process also takes place in the manner described above. In order to bring the guide surfaces to rest, however, a number of openings 5 are arranged in the pipe end 6 in accordance with the number of guide surfaces, into which the guide surfaces 3 are attached. The side walls 7 of these openings 5 are, in order to facilitate the screwing in and application, preferably worked out at an angle such that the openings 5, seen in the axial direction, assume an approximately trapezoidal shape, the short side of which is on the outer circumference of the pipe.

Another embodiment is shown in Fig. 5, in which a funnel 8, for example made of sheet metal, placed on the pipe end and in a suitable manner Way is attached. To ensure smooth loading, the pipe end can be adjusted accordingly the funnel slope should be beveled. The same purpose is also achieved by procrastination and fastening a more or less strong ring 9 achieved on the pipe end (Fig. 6 and 7) which may or may not be beveled inside (10 in Fig. 6) (11 in Fig. 7). The same applies to the end of the pipe.

For guide surfaces that protrude only a little, it may be enough, just bevel the end of the pipe inwards. Of course, a Wall reinforcement can be provided, which is conical inwardly.

The device according to the invention offers in a simple manner the possibility the guide surfaces on rocket or long projectiles quickly come to rest during the loading process to bring to the projectile body, so that the projectile in its launch position in the barrel can be brought.

Claims (2)

PATENT CLAIMS: 1. Device for introducing with approximately tangential protruding over-caliber guide surfaces provided tail units in the pipe a launcher, characterized by a known per se, at the muzzle or attached to the barrel end of the launcher, which when inserting the projectile into the barrel, applying or winding up the over-caliber causes tangentially protruding tail surfaces on the tail boom. 2. Establishment according to claim 1, characterized in that the pipe mouth or the pipe end (1) provided in a manner known per se with a funnel (2) or designed as such is in which the over-caliber guide surfaces (3) with their beveled edges (4) can be attached and the guide surfaces (3) by pressing the projectile into the tube (1) can be applied to the tail girders in a winding sense.
