Definitions

the invention relates to a projectile weapon, in particular a grenade launcher with a weapon barrel, preferably with a base, optionally arbitrarily operable, ignition device and preferably support devices, in particular base plate, bipod and / or the like.
Proposals have become known for avoiding the deviations in the departure angle caused in this way and thereby improving the hit pattern.
a stiffening body is provided in the mouth region of the weapon barrel, which increases the area moment of inertia of the barrel there.
DE-OS 30 46 639 are, for example, substantially laterally from the same along the entire extent of the weapon barrel arranged or provided this stiffening organs, with the major disadvantage of significantly increased space requirements and weapon weight.
it has also become known to provide an essentially radial elevation, i.e.
a kind of rib for cooling on the outside of them, at least over part of their extent, encircling the barrel on the outside, the cross-sectional area of which can be of the order of mm 2 , for example.
the rib forms a kind of rib alignment, which contributes to a greater load-bearing capacity of the barrel due to the enlargement of the outer surface, for example due to an increased cooling effect which permits a higher weft sequence.
the invention thus relates to a projectile weapon, in particular a grenade launcher with a weapon barrel, preferably with a base, optionally arbitrarily actuable ignition device, and preferably support devices, in particular. Special base plate, bipod and / or the like.,
the weapon barrel on its outside at least over part of its extent having substantially all-round, substantially radial elevations and / or depressions, and consists essentially in that the projectile weapon has a gun barrel with a Has a plurality or multiplicity of elevations and / or depressions which run essentially adjacent to one another, are essentially complete, are not closed, preferably do not intersect, and are essentially spiral, helical or helical in shape.
a slope of 2-12 °, preferably 3-6 0 have.
the slope mentioned here refers to the course of the elevations or depressions in the development of the pipe jacket.
the damping effect is significantly influenced by the area of the elevations or depressions on the weapon barrel. It is expedient if at least 35%, preferably at least 50%, of the outer surface of the weapon barrel has these elevations and / or depressions.
a high number of stiffening elements on the tube and a high damping effect on the vibrations building up in the tube when firing can be advantageously achieved if a plurality of elevations and / or depressions extending parallel to one another each have the common, essentially spiral, helical or helical Has history.
flanks of the recessed areas between the elevations or the depressions are rounded toward the bottom of the depression, preferably the bottom itself is approximately arc-shaped, preferably circular-arc-shaped and merges into the flanks.
the cooling effect can be increased by aligning the flanks of the raised areas between mutually adjacent depressions or the elevations radially toward one another at an acute angle ⁇ .
the angles can e.g. be between 1 and 60 °, preferably about 5 - 15 °.
the essentially multi-course spiral, helical or helical elevations or the areas between depressions have a smaller cross-sectional area, preferably a smaller width at the base, than the areas or depressions lying between the elevations, cooling can be improved in addition to optimized vibration damping.
a favorable ratio of the cross-sectional areas of the lower points to those of the higher points on the outside of the tube can e.g. be about 1.2 to 3.
Acceleration of the cooling effect and reduction in the tendency to vibrate can be influenced further advantageously if the elevations and / or depressions have a spiral, helical or helical course widening in their pitch or their distance from one another towards the weapon barrel muzzle.
an increased longitudinal stiffening of the barrel and a so-called reinforcing chimney effect for cooling are provided in the region of the muzzle of the weapon barrel which does not represent a clamped end.
the multi-course ribs or '. Grooves in the area of a clamp can be interrupted.
the elevations and / or depressions themselves can be designed as anchoring elements for such clamps or the like.
the clamp can have a multi-course, thread-like cooperable design corresponding to the design of the elevations and / or depressions, so that it can practically be screwed onto the pipe.
the elevations can be applied in one piece to the weapon barrel or applied to it.
FIG. 1 shows a grenade launcher according to the invention in an oblique view
FIG. 2 shows a detail of the weapon barrel in a top view
FIGS. 3 to 6 show sections through the wall of weapon tubes designed according to the invention.
the weapon barrel 1 is connected at one end to a base piece 2 which is pivotally mounted on all sides with ball pins 20 in a base plate 3.
the pipe 1 is connected by a clamp 13 via a shock-absorbing device 11 to a side directional drive 41, which in turn is arranged on a height directional drive 42 of a bipod 4.
the launcher tube 1 has on its outside here from the base piece 2 to approximately the clamp 13, helically circumferential and parallel groups G each having three equally spaced depressions 101, of the same profile, approximately in the manner of a three-start thread. Instead of the depressions, surveys can be provided in the same way.
the areas between the grooves or elevations bring about a damping which significantly reduces the tendency of the barrel to vibrate when passing through the storey and thus increases the accuracy of the hit, as well as improved external cooling of the barrel.
FIG. 2 In the top view of FIG. 2 on a differently designed weapon barrel 1, it is shown how a group G of four roughly triangular profile elevations 100 and non-raised areas 101 therebetween, each with the same distances g from one another and a pitch angle ⁇ , that is to say the pitch of the helix Flattening are arranged like a helix. If the angle ⁇ is approximately 2 to 12 0 , particularly preferably 3 to 6 0 , then are special good damping when passing through the storey and high cooling effect.
FIG 3 shows a section of a longitudinal section through the wall of a further weapon barrel 1 up to the axis A, and shows on the outside of the cross-section substantially similar trapezoidal elevations 100, between which non-raised areas 101 extend, the cross-sectional area Q 1 of the elevations and their base width b 1 is smaller than that Q 2 or b 2 of the lower regions 101 lying therebetween.
the elevations 100 and intermediate regions 101 likewise have a multi-helical course.
two smaller depths t 2 grooves 101a, 101a are arranged between two grooves 101, 101 'which have a greater depth t 1 and which here spiral around a gun barrel 1 ;
three identical grooves 101 a, 101 a ′, 101 a ′′, all of the same depth t 1, are arranged between the passages of a single groove 101 having a larger width b 1.
FIG. 6 shows how the elevations have flanks 102 tapering radially outwards at an acute angle ⁇ , which here arcuate into a semicircular groove base 103.
