DESCRIZIONE DESCRIPTION
? L'invenzione ha per oggetto una disposizione di proiettile ad alta penetrazione secondo il principio di base della rivendicazione 17 The invention relates to a high penetration projectile arrangement according to the basic principle of claim 17.
Una disposizione della tecnica nota forma oggetto detla domanda di brevetto italiana Secondo questa disposizione viene aumentato lo spazio disponibile per la carica propellente in misura- . .tale che dal.corrispondente incremento della carica_ deriva una pi? elevata potenza balistica interna.'-. . Nel proiettile,alettato secondo.la domanda .di brevet- _ to italiana,.summenzionata,..e.stato.,osservato.che.la _ potenza distruttiva ? maggiore su bersagli semplici . An arrangement of the prior art is the subject of the Italian patent application. According to this arrangement, the space available for the propellant charge is increased to such an extent that the corresponding increase in the charge results in a higher internal ballistic power. In the finned projectile according to the aforementioned Italian patent application, it has been observed that the destructive power is greater on simple targets.
_che.su bersagli.multipli__ _ _ _ _that.on.multiple.targets__ _ _ _
_ ^_ L 1invenzione ha lo scopo di migitorare,_ _con una disposizione di proiettile.ad_alta..penetra- __ _ zipne__del_tipo gi?_nqto_la potenza distruttiva del_ _ proiettile_alettato su obiettivi_multipii anche_ in condizioni difficili - e di sistemare, a questo^ fine, frangibilmente, in modo mirato, il proiettile a-_ Iettato nella zona della punta;'e di portare quindi ; quanto pi? possibile la massa di penetratone disponibile sul bersaglio. The invention has the purpose of improving, by means of a highly penetrating projectile arrangement of the type already introduced, the destructive power of the finned projectile on multiple targets even in difficult conditions - and to this end, to arrange the finned projectile in a targeted and destructive manner in the tip area, and thus to bring the available penetrating mass to the target as much as possible.
Questo problema viene risolto secondo la invenzione definita nella parte caratterizzante della rivendicazione 1? Si realizza con questa vantag giosamente non ssoltanto una potenza distruttiva di completa efficacia sul bersaglio aumentata per effetto della maggiore carica, ma anche un prolungamento della sua attivit? che, con un tipo affusolato di penetratone, risultato molto opportuno, combinano il _ vantaggio di una ben definita frangibilit? con_quello, ogni volta il pi? grande possibile, di poter dispor- re continuamente-di -una massa definita per--la -d?siru-. - - zione di obiettivi multipli. Inoltre,-la prevista in- -- -elusione-del?cono di-forzamento nella zona di connes ? . -sione-comporta,vantaggiosamente..una-aumentata misura - della -gittata del penetratcre.__ __ . _ _ - - l'invenzione verr? ora .descritta in .dettaa _glio con.riferimento ad.un esempio preferito di attueS _ zione_illustrato.nel disegno.,schematico ailegato con ? _ esclusione .di.alcuni._particolarijessenziali _ K?Q-< _ _ _ La.,singola figura deludisegno mostra,una ..< This problem is solved according to the invention defined in the characterizing part of claim 1. This advantageously achieves not only a fully effective destructive power on the target increased by the effect of the larger charge, but also a prolongation of its activity which, with a tapered type of penetrator, a very suitable result, combines the advantage of a well-defined frangibility with that, always as large as possible, of being able to continuously have at disposal a defined mass for the destruction of multiple targets. Furthermore, the foreseen evasion of the cone of forcing in the connection zone advantageously entails an increased measure of the range of the penetrator. __ __ . _ _ - - the invention will be now described in detail with reference to a preferred example of implementation illustrated in the accompanying schematic drawing with the exclusion of some essential details.

In the rear area, the peripheral surface, not illustrated in detail, of the forcing cone 24 is closely surrounded by the internal surface 52 of the propellant cage? The internal surface 52 in a . annular, circular edge 18 which, as described, limits the connection area 407 at the rear. According to the schematic illustration, each of the segments of the propellant cage has a rear support or support fin 48 which extends radially towards a tubular internal surface not shown. This latter advantageously ensures that during the path of the highly penetrating projectile array along the launch tube, a suitably high radial pressure force also acts in the rear lateral area of the propellant cage 30 and thus is achieved in cooperation with

The circular annular edge 18 defines the shape of the rear lateral limit of the connection area 14, so that by means of the illustrated arrangement 3i a greater range is advantageously obtained which takes into account not only the highly compact penetrator element (preferably a sintered alloy of a heavy metal based on volfranium or even depleted uranium), but also the considerable rear length of the penetrator. The advantage of the desired range of the pre-penetrator is associated with the high impact resistance of the finned projectile which remains, so that during the path through a further pre-armouring it is not possible to achieve a greater distance from the penetrator. there is still an adequate mass of corresponding kinetic energy available on the main armor!
