Description
Shell for gun with smooth-bore barrel The present invention relates to a method for converting certain mortar ammunition for use as fin-s stabilized, non-rotating shells in smooth-bore guns, in particular tank guns. The invention also includes ammunition which has been converted in accordance with this method.
The invention thus includes, on the one hand, a method for converting mortar shells for use as fia stabilized, non-rotating shells in smooth-bore gun barrels, in particular tank guns, of essentially the same calibre as the mortars for which the shells in question were originally intended, and, on the other hand, a method for converting mortar shells, of smaller calibre than the gun barrels in question, to subcalibre non-rotating shells provided with discarding sabots, where the discarding sabots are separated in a known manner from the shells outside the muzzle of the gun barrel.
The invention is considered to be of great value since there is plenty of mortar ammunition in stockpiles, and the high-explosive mortar shells in particular have well-designed shell bodies with good fragmentation properties, and at the same time there is some need for high-explosive shells for the tank divisions, who generally have artillery pieces with smooth-bore barrels.
Of course, the invention also includes the converted shells and the complete rounds of which these form part.
- la -According to one aspect of the present invention, there is provided a method for converting mortar shells into shells for use in smooth-bore gun barrels having an interior surface, the mortar shells including a warhead having a front end, a rear end, a tail fin, and a propellant charge, said method comprising the steps of: attaching a guide casing to at least the rear end of the warhead, said guide casing including an outside surface, said guide casing supporting at least the rear end of the warhead, said guide casing adapted to the caliber of the smooth-bore gun barrel that the converted shells are to be fired from; and attaching a bourrelet to said outside surface of said guide casing for sealing between the converted shells and the interior surface of the smooth-bore gun barrel that the converted shells are to be fired from.
According to another aspect of the present invention, there is provided a method for converting a mortar shell including a propellant charge into a shell for use in a smooth-bore gun barrel having an interior surface, said method comprising the steps of: providing a mortar shell including a warhead having a front end, a rear end, an outer surface, and a tail fin; providing a guide casing including an inner surface for engaging at least a portion of the outer surface of the warhead, said guide casing having an outer surface adapted to be utilized with a smooth-bore gun barrel of a caliber that the converted shell is to be utilized with;
providing a bourrelet for attaching to the outer surface of said guide casing to seal a space between the converted shell and the interior surface of the smooth-bore gun barrel that the converted shell is to be fired from; attaching the guide casing to at least the rear end of the warhead, said guide casing supporting at least the rear end of the warhead; and attaching said bourrelet to said guide casing.
- lb -According to still another aspect of the present invention, there is provided a converted shell converted from a form for use with a mortar and including a propellant charge to a fin-stabilized non-rotating shell for use with a smooth-bore gun barrel said converted shell comprising: a warhead of the mortar shell, said warhead including a front end, a rear end, and an outer surface; a guide including an inner surface engaging at least a portion of the outer surface of the warhead, said guide having an outer surface adapted to be utilized with a smooth-bore gun barrel of a caliber that the converted shell is to be utilized with; and a tail fin attached to one of said warhead or said guide.
According the invention, the actual conversion is carried out in such a way that the warhead of the original shell is kept unchanged, while its original tail fin, with internal propellant charge chamber, is either replaced by a new tail fin adapted to the new and higher velocity of exit (Vo) of the projectile, or is merely deprived of its internal propellant charge, at the same time as which the warhead is always provided with a guide vJ0 95130875 218 9 3 .~ ~ PCTISE95100364 part or guide casing which is adapted to the calibre gauge of the smooth-bore barreltin question and Which is preferably provided with ;'a.s~ bourrelet of the type regularly used as a powder gaa seal is barrels of the type is question here.
Ia purely general terms, the ordinary tail fin of the mortar shell is usually secured oa the warhead by means of a screw thread. Particularly in those cases where the tail fin is to be replaced by a new one, the 1D said screw thread can be used for securing the guide casing on the warhead, while the guide casing is is turn provided with a screw thread for the screwing-on of the tail fin.
Moreover. the shells converted in accordance with the present invention are always intended to be supplemented with the propellant powder charge which is appropriate for the gun in question sad which, is the case of task guns. generally involves fixed propellant charges, and with which they can be combined to form complete rounds.
The invention further includes two alternative possibilities for converting the mortar shell for use in smooth-bore barrels. The first variant is based on mortar shells intended for mortars of the same, or essentially the same, calibre as the smooth-bore guns in which the converted shells are intended to be used. and in this case the guide casing is mainly is the form of a casing which encloses and supports the rear part of the warhead of the original shell, the inside of which casing is shaped matching the outer shape of the warhead in order to increase the strength of the warhead against the firing stresses. and the rear portion of Which casing is designed to be relatively strong, and the front portion of which casing consists of an approximately tubular and relatively thin-walled portion which adjoins the outer periphery of the warhead is the vicinity of its maximum diameter. In the more solid rear portion of the guide casing. there is also a bourrelet groove which is provided with a conventional bourrelet.
-'3 -The second variant of the invention is based on a mortar shell of smaller diameter than the gun barrel in question, sad this shell is provided with a'guide casing designed in~accordaace with the principles applying to discarding sabots for subcalibre projectiles, i.e. it is designed is three or more parts is the longitudinal a direction, these parts being held together by mesas of locking bands which are intended to be torn off by the effect of the ram pressure when the projectile leaves the barrel. As in the first variant of the invention, the guide casiag/discarding sabot is question here is also given a relatively strong rear portion, with as inner shape adapted to the outer shape of the warhead in order to increase the strength of the warhead against the firing stresses, and With associated guide grooves for a conventional bourrelet, and a more thin-walled front portion which expediently opens out is a cup shape at the front is order to offer a good point of attack for the relative wind.
The method and the arrangement according to the invention, and the finished round which is obtained in accordance therewith, are defined is the attached patent claims sad will now be described in somewhat greater detail is connection With the attached figures.
Fig. 1 shows a side view of the starting point, namely a conventional high-explosive mortar shall, and Fig. 2 shows a partially cut-away side view of the converted high-explosive shell adapted for use in unrifled gun barrels.
Fig. 3 shows a partially cut-away side view of a converted subcalibre-type shall provided with discarding sabot.
The mortar shell 1 shown is Fig. 1 comprises a front warhead 2 (also seen is Fig. 2) and a rear tail fin 3 with inner propellant charge.
The shall 4 shown in Fig. 2, sad modified for use in unrifled barrels, comprises the explosive-filled warhead 2, while the tail fin 3 has been disassembled and its assembly screw thread 5 has been used for screwing-on of the guide casing 6. The latter has relatively thin-walled, tubular front part 7, a more solid rear portion 8, which encloses the rearwardly narrowing rear part 2a of the warhead 2, and a rear part 11 on which a new tail fin 12 is firmly screwed, the said tail fin 12 being adapted to the new and higher velocity of exit (Vo) of the converted shell.

In this case the starting point is a shell 14 of smaller calibre than the barrel in question, and here the original tail fin 15 has been retained, but deprived of its original internal propellant charge. The fuse 16 has also been retained in its original form. In contrast, the shell has been supplemented with a discarding sabot (guide casing) 17 a-c, which is divided in three equal parts in the longitudinal direction and is held together by connection rings 18 and 19 and also the bourrelet 20. These come to be torn off by the ram pressure when the shell leaves the barrel muzzle, after which the discarding sabot parts leave the shell in a known manner, with the shell continuing its trajectory alone. The three parts 17 a-c of the discarding sabot are designed in such a way that the latter has a relatively solid rear and central portion 21, which fits closely against, and supports, those parts of the original shell body which, upon firing, are exposed to the greatest stresses, while its front portion 22 is relatively thin-walled and opens out in a cup shape at the front around the forward part of the shell body 14, in order to give the ram pressure a good point of attack there.
