  • TITLE "Turret , in particular for naval applications , provided with a device for moving an ammunition guidance system"
  • the present invention relates to a turret , in particular for naval applications .
  • turrets which consist of a structure supporting and containing an artil lery installation .
  • the turret lies on a deck - or, more generally, on an upper surface - of a ship or a terrestrial vehicle , such as a military tank or the like .
  • a turret is moved - typically rotated - on the deck, wherein motion i s obtained, for example , through a combination of a traversing rotation ( i . e . a rotation about a substantially vertical azimuthal axis ) and an elevation rotation ( i . e . a rotation about a substantially hori zontal zenithal axis ) .
  • the component assemblies forming the turret are commonly distributed between the so-called “traversing mass” and “elevating mass” .
  • the components forming the "traversing mass” are substantially located at the turret base and secured to a support structure .
  • the components constituting the so-called “elevating mass” are generally rotatably supported by the components constituting the so-called “traversing mass” .
  • Some turret types employ an ammunition guidance system configured to direct a guided piece of ammunition to be fired by the firearm towards a target by means o f an electromagnetic emission, e . g . a radar beam or a laser ray . It is therefore appropriate to employ in the turret a device for moving the ammunition guidance system, which can orient the latter to direct the radar beam or the laser ray towards the target .

Barrel 18 is configured to fire guided ammunition through itsel f .
  • traversing part 14 comprises a pair of lateral portions 20a, 20b mutually defining an embrasure 22 , in which elevating part 16 i s mounted rotatable about elevation axis X . Moreover, barrel 18 crosses embrasure 22 and protrudes frontally therefrom .
  • turret 10 further comprises an ammunition guidance system 24 configured to direct a guided piece of ammunition to be fired through barrel 18 towards a target by means of an electromagnetic emission, e . g . a radar beam or a laser ray .
  • an electromagnetic emission e . g . a radar beam or a laser ray .
  • ammunition guidance system 24 is mounted rotatably integral with traversing part 14 , rotating together with it about traversing axis Y .
  • Turret 10 comprises a protection device 26 configured to assume an opening condition ( shown in Figure 1 ) and a closing condition (not shown) .
  • protection device 26 is configured to move between the closing condition and the opening condition, e . g . progressively assuming one or more intermediate conditions during the trans ition between said closing and opening conditions .
  • In the closing condition protection device 26 encloses and protects ammunition guidance system 24 .
  • In the opening condition protection system 26 clears and exposes ammunition guidance system 24 .
  • ammunition guidance system 24 is mounted to traversing part 14 .
  • ammunition guidance system 24 is situated laterally relative to barrel 18 .

  • protection device 26 In the clos ing condition, protection device 26 encloses and protects - in particular by covering it -ammunition guidance system 24 within traversing part 14 , e . g . within the first lateral portion 20a of the latter .
  • protection system 26 clears and exposes - in particular by uncovering it -ammunition guidance system 24 outs ide traversing part 14 , e . g . outside lateral portion 20a of the latter .
  • traversing part 14 internally defines a reclosable cavity 28 that houses ammunition guidance system 24 .

  • covering element 30 makes a rototranslation between a frontal position (not visible in the drawings ) - corresponding to the closing condition - and a raised position - corresponding to the opening condition .
  • covering element 30 In the opening condition shown in Figure 1 , covering element 30 is in said raised position, in which it opens and clears reclosable cavity 28 , thus exposing ammunition guidance system 24 . In the closing condition (not shown in the drawings ) , covering element 30 is in said frontal position, in which it closes and covers reclosable cavity 28 , thus protecting ammunition guidance system 24 .
  • ammunition guidance system 24 - together with its covering element 30 in the embodiment illustrated herein - completes the outl ine of lateral portion 20a, making it substantially symmetrical to lateral portion 20b with respect to embrasure 22 .
  • the closing condition typically occurs when turret 10 is inoperative , i . e . when barrel 18 is not being used for firing against a stationary or moving target .
  • ammunition guidance system 24 will be covered and completely hidden within traversing part 14 , in particular within the first lateral portion 20a .
  • protection device 26 will ensure protection of ammunition guidance system 24 from the outside environment , while also making it less trackable by radar .
  • the opening condition generally occurs when turret 10 is operative , i . e . when barrel 18 is being used for firing against a stationary or moving target .
  • Ammunition guidance system 24 can thus be directed towards the environment outside turret 10 in order to generate the electromagnetic emission towards a target to be hit with a piece of ammunition fired through barrel 18 .
  • covering element 30 is configured to guidedly rototranslate over traversing part 14 , in particular in such a way that in the frontal position - i . e . in the closing condition -covering element 30 will face substantially in the same direction in which the barrel can be oriented, while in the raised position - i . e . in the opening condition - covering element 30 will face upwards , in particular above traversing part 14 .
  • covering element 30 is substantially concave .
  • its sunken portion faces towards cavity 28 of first lateral portion 20a, thus further expanding such cavity 28 at the front .

Abstract

La présente invention concerne une tourelle, en particulier pour des applications navales, qui comprend une partie de pointage en direction et une partie d'élévation pouvant tourner d'un seul tenant avec la partie de pointage en direction. Un canon est supporté par la partie d'élévation et peut tourner d'un seul tenant avec celle-ci autour de l'axe d'élévation (X1). Le canon est configuré pour tirer des munitions guidées à travers lui-même. Un système de guidage de munitions (24) est configuré pour diriger une munition guidée vers une cible au moyen d'une émission électromagnétique. Un dispositif mobile (100), sur lequel est monté le système de guidage de munitions (24), est configuré pour déplacer ce dernier de manière à orienter l'émission électromagnétique vers la cible. Le dispositif mobile (100) est monté sur la partie de pointage en direction (14) et comprend un cadre (102) qui supporte de manière rotative le système de guidage de munitions (24) autour d'un axe de déplacement azimutal ou de pointage en direction (Y1) et d'un axe de déplacement zénithal ou d'élévation (X1).
