Definitions
- the technical field of the invention is that of large caliber weapons, and in particular, large caliber weapons with rear loading.
- a large caliber rear-loading weapon comprises a weapon tube mounted in a cradle inside which it slides on slides during recoil, and a breech block.
- a locking mechanism is located at the rear of the breech block.
- Such a locking mechanism is, for example, a screw mechanism comprising a cover and a screw intended to screw into the chamber of the weapon tube.
- the weapon in order to be able to take into account particularly fleeting targets with a satisfactory possibility of hitting, the weapon must be capable of firing short bursts at a high rate almost instantly.
- a barrel weapon comprises, on the one hand, a movable tube during firing relative to a support and, on the other hand, at least one ammunition barrel having at least two chambers which can be placed one at a firing station and the other at a feeding station by rotation of the barrel.
- this large caliber weapon includes two rotating barrels mounted behind the breech block of the weapon. Each barrel has housings intended to receive ammunition.
- the weapon further comprises means for moving the ammunition in translation, arranged behind the barrels, and configured to push towards the weapon tube an ammunition contained in one of the barrel housings and aligned with the axis of the tube weapon.
- Such a barrel weapon makes it possible to minimize the transport times of the ammunition between their storage location, in one of the barrel housings, and the chamber of the weapon where the ammunition will be ignited and fired.
- barrels are bulky and heavy and dedicated solely to the storage and conveying of the ammunition in front of the weapon chamber. Chambering the ammunition involves means of positioning the ammunition, then the use of means of closing and opening the breech of the weapon.
- the barrel(s) containing the ammunition must often be placed at a distance from the closed breech to allow the weapon to recoil, which increases the size of the vehicle or the turret carrying the weapon and modifies its inertia.
- the aim of the weapon on site must be brought back into alignment with the barrel(s), which increases the duration of a repeating firing sequence.
- the present invention thus aims to propose a solution making it possible to reduce the reloading time between several consecutive shots (redoublement) for a large caliber weapon, and therefore to increase the rate of fire of a large caliber weapon.
- the present invention also aims to respond favorably to the constraints of reducing bulk while allowing duplication for any site of the weapon tube, and in particular in direct fire.
- the invention also makes it possible to choose what type of ammunition will be fired with the next shot.
- the solution according to the present invention is based on the presence of a plurality of chambers intended to contain large caliber ammunition ready for firing, each chamber being movable between a position in which it can be reloaded and a position in alignment with the tube weapon in which the chamber is closed at its rear end and opens at its front end into the weapon tube.
- the present invention relates to a large caliber weapon comprising a cradle and a recoiling mass mounted movable relative to the cradle, the recoiling mass comprising a weapon tube having a longitudinal axis and a breech assembly, the breech assembly comprising a block breech secured to the weapon tube, a breech support movable in axial translation relative to the breech block and coupled to a breech head, characterized in that the breech assembly further comprises a plurality of loading chambers intended to each receive an ammunition, a mechanism for moving the chambers configured to support the chambers and successively place one of the chambers in a firing position, namely between the breech block and the breech head and in alignment with the the longitudinal axis of the weapon tube, and at least one other chamber in a feeding position, in which the at least one chamber is adapted to receive ammunition through its rear end, and a locking mechanism configured to move the head breech and the chamber placed in the firing position between an un
- breech assembly it is possible to reload the empty chamber(s) in the feeding position while a chamber is locked with ammunition ready for firing, and therefore to increase reactivity by reducing the time which elapses between several consecutive shots. It is also possible to place a chamber having suffered a failed shot in the feeding position, and therefore to manage a non-fired shot outside the axis of the weapon tube, while having a chamber locked with an ammunition ready to fire, so that such a non-fired shot management operation does not reduce responsiveness.
- the breech assembly according to the present invention allows rapid deployment of the ammunition while having a compact structure.
- Reloading empty chambers can be done manually. Reloading of empty chambers can also be done automatically or semi-automatically via a reloading system. In this case, preferably, the reloading system is a doubled reloading system, making it possible to reduce the reloading time.
- the plurality of loading chambers can be loaded with various munitions. Thus, the presence of several chambers allows you to have the choice between several ammunition.
- the chamber movement mechanism is supported by the cradle and comprises: a drawer capable of mechanically supporting the plurality of chambers arranged next to each other parallel to the longitudinal axis and a translation movement actuator connected to the drawer to move the drawer in translation relative to the cradle in a direction of translation transverse to the longitudinal axis.
- Such a movement mechanism based on a simple translational movement, allows simple and rapid movement of the chambers, and therefore rapid choice of the ammunition ready for firing.
- the translational movement actuator is a motorized actuator comprising an electric or hydraulic motor, in particular a geared motor, coupled to the drawer by a pinion-rack connection.
- Such a translation movement actuator is simple to integrate, reliable and inexpensive.
- the drawer comprises a plurality of through axial housings, each through axial housing being shaped to receive a loading chamber with a clearance between the chamber and the housing, the cradle comprising stop stops in axial translation, secured to the cradle, arranged to be in close proximity to the front and rear ends of each chamber placed in the feeding position and configured to leave the opening at the rear end of each chamber free.
- Such clearance allows the chamber placed in alignment with the longitudinal axis of the weapon tube to slide axially in the housing, in other words to be movable axially relative to the drawer and the cradle.
- the stops in axial translation make it possible, despite the presence of this play, to prevent the chambers which are not placed in alignment with the weapon tube from sliding in their housing, in other words the chambers in the position of power supply are held in a fixed position relative to the drawer.
- the breech head is a screw breech head comprising an external thread capable of cooperating with a corresponding internal thread provided at the rear end of each chamber, each chamber comprising an external thread at its front end capable of cooperating with a corresponding internal thread provided in the breech block
- the locking mechanism being a screw lock mechanism comprising a linear movement actuator connected to the breech support for linearly moving the breech support relative to the breech block along the longitudinal axis, a rotational movement actuator connected to the breech head to drive the breech head in rotation relative to the breech support around the longitudinal axis, and a disengageable lock capable of moving between a position engaged, in which the chamber placed in the locked position is integral in movement with the breech head, and a retracted position in which said chamber is released to rotate relative to the breech head, the linear movement and rotational movement actuators being configured to obtain combined movements of linear displacement and rotation of the bolt head.
- the disengageable bolt allows the chamber to be extracted from the breech block by recoil and rotation of the breech head.
- the combined movements of linear movement and rotation of the breech head allow the screwing of the breech head into the chamber and the screwing of the chamber into the breech block.
- the combined movements of linear movement and rotation of the breech head as well as the movement of the disengageable bolt allow the chamber to be unscrewed from the breech block and then the breech head to be unscrewed from the chamber.
- the linear movement actuator comprises a guide member, in particular in the form of a pair of axial rods, secured to the cylinder head support and slidably mounted in the cylinder head block, which guide member is driven in translation by a translation drive member, in particular a cylinder or a geared motor, supported by the cylinder head block.
- a translation drive member in particular a cylinder or a geared motor
- the rotational movement actuator comprises a rotational coupling member integral in movement with the cylinder head head and mounted free to rotate relative to the cylinder head support, which rotational coupling member is driven in rotation by a rotation drive member, in particular a geared motor, integral with the receding mass.
- a rotation drive member in particular a geared motor
- the internal and external threads can each have several threads.
- the breech block comprises a deformable joint positioned against the rear end of the weapon tube and configured to be compressed between the front end of a chamber in the locked position and the rear end of the weapon tube.
- Such a deformable seal ensures sealing at the front of the chamber.
- each loading chamber defines a breech head receiving space extending from the rear end of the chamber to an ammunition receiving space, the breech head receiving space having a first cross section and the ammunition receiving space having a second cross section which is smaller than the first cross section.
- the junction zone between the bolt head receiving space and the ammunition receiving space has a shoulder which limits the insertion of the bolt head into the chamber and which ensures good sealing at the rear of the chamber when the bolt head closes the rear of the chamber.
- the internal thread provided at the rear end of each chamber extends from the rear end of the chamber to the rear end of the ammunition receiving space of the chamber, the diameter of the internal thread being greater than the diameter of the ammunition receiving space.
