Description

Gun projectile, especially artillery projectile.

In the case of artillery projectiles, it is known that the floors or thrust surfaces by sabot, pressable funnel-shaped steel sleeves for conical pipes and the like to enlarge. These types of thrust area enlargement have considerable Disadvantages, which consist, among other things, in the fact that, e.g. with sabot, larger barrel calibers and thus heavier pipes or conical ones that are difficult to manufacture in the case of steel sleeves Tubes for complex projectiles are required. There are also bigger and heavier ones dimensioned floor pieces and the like. More.

While in the previously known attempts to increase performance the gun or projectile parts required for this the weapon dimensions in radial Expand direction, these disadvantages are completely avoided by the invention, because, according to the invention, the propellant gas is applied directly to the thrust or work surfaces on the floor and / or on the sabot are larger than the circular floor area of floor 0 The thrust surfaces on the projectile are arranged one behind the other in such a way that e.g. first acted upon primary thrust surface is provided with openings through which a friction gas can be applied to a downstream secondary thrust surface. the Passages can thereby ring-shaped on the circumference of the rear of the projectile or be arranged centrally o The connection between the primary thrust surface on the one hand and the secondary surface, on the other hand, expediently has the shape of a pointed cone or a cone jacket or the like.

Both the central and the annular propellant gas passage openings can be designed as pressure increase means, e.g. diffuser or derglo. The those Shear surfaces and their connecting parts are expediently extension pieces, e.g.

made of plastic or the like .. detachable from the projectile and in the manner of sabot discardable. If the primary piece remains on the floor, openings from the floor space provide to atmosphere for pressure equalization.

There is a significant advantage of the projectiles according to the invention inter alia in that they are used in conjunction with cases or charge cases, cartridges, etc. can be locked. As the designs and figures show, are the thrust area of the projectile after deduction of the passage openings almost twice as big as a normal floor O This has significant advantages, such as e.g. retention of the normal barrel and bullet caliber, short barrel length, light pieces of soil, etc.

Should the secondary thrust surface only be at a certain position of the Projectile in the tube, e.g. in the area of the tube mouth, can be used to e.g. to influence the pressure curve, can the inlets be dammed to the secondary thrust area. It is also possible to use ammunition after the Invention to fire in high pressure guns, creating a multi-stage high pressure gun is achieved.

In addition, the space between the two thrust surfaces can also be used as Propellant carriers are used.

In Figures 1 to 3, the invention is shown for example. figure 1 shows a projectile with an annular disk-shaped primary thrust floor and a circular one Secondary sliding floor, while Figure 2 is the primary sliding floor and the secondary sliding floor are roughly ring-shaped. FIG. 3 shows the application of the invention to a frictional mirror bullet again.

With 1 is the floor, with 2 the extension or the rear of the floor with the gas passage opening 3 to the secondary sliding floor 4, the connecting surfaces have the shape of a cone. 6 is a primary thrust surface with a passage opening 7 to the secondary thrust surface 8; Both thrust surfaces are connected by the cone 9. A sabot is designated by lo, which has a primary thrust surface 11 and a secondary surface 13 has to which the inflow opening fA leads.

The figures show only examples of the invention, which are also shown in forms and combinations other than those shown may be used.
