Abstract

FIELD: constructions of turrets of armored military vehicles.

SUBSTANCE: the mounting surface with a stop for installation of the weapon taking up the recoil force, or support with the weapon block is made in the rear part of the cover, which makes it possible to perform the frontal armored assembly without any embrasure slots. The weapon block support is made detachable.

EFFECT: enhanced armoring stability of the turret, and hence the survivability of the military vehicle as a whole, and enhanced maintainability of the turret.

Description

The invention relates to the field of military equipment and, in particular, to the structures of towers of military armored vehicles with anti-shell armor, rocket and cannon armament, and which are required to survive the structure, reliable protection of the crew and maintainability.

A well-known tower of a military armored vehicle (see RF Patent No. 2112914), selected as a prototype, contains a bottom sheet, a frontal armor unit with embrasure cutouts, complex landing surfaces for installing and fixing a gun with trunnion assemblies, side, aft sheets and a roof.

The specified tower has the following disadvantages:

1. Low ballistic resistance of the frontal armor unit in the presence of weakened zones in its central part, because of which equivalent ballistic protection of the entire frontal projection of the turret of a military armored vehicle is not provided. Each hit in these areas with armor-piercing-projectile shells, anti-tank grenades and anti-tank guided rockets is accompanied by penetration of armor and damage to the crew.

2. Low maintainability of the tower during combat damage. When hit means, including high-explosive shells, hit the axle nodes of the weapon in the frontal armor of the turret, which makes it impossible to dismantle the weapon, resulting in less maintainability.

3. A large moment of turret unbalance, since the frontal armor unit of the turret has a mass greater than the total mass of side and stern sheets, as a result of which the turret’s rotation speed decreases and a large load arises on the turret rotation drive mechanisms.

The technical results of the invention are to increase the ballistic resistance of the frontal armor unit of the tower, reduce the complexity of replacing weapons in case of damage or when upgrading a military armored vehicle, increase the speed of rotation of the tower.

These technical results are achieved by the fact that in the proposed tower the frontal armor unit is made without embrasure cutouts, and in the aft part of the roof, on the opposite side of the frontal armor unit, a landing surface is made parallel or at an angle to the plane of the bottom sheet to allow the installation of a removable support on it with a block of weapons. To perceive the recoil effort and maintain a stable position of the support with the weapon block, the landing surface is equipped with a stop and fasteners.

Placing a removable support for the weapon block on the landing surface in the aft part of the roof of the tower allows the frontal armored unit without embrasures for the installation of artillery and small arms, which leads to an increase in the projectile resistance of the tower, and also minimizes the moment of its imbalance.

In the study of other technical solutions in this technical field, signs that distinguish the claimed device were not detected. This allows us to conclude that the claimed device has a novelty and does not follow explicitly from the existing level of technology.

The invention is illustrated by drawings, where figure 1 shows a tower of an armored military vehicle, top view; figure 2 shows a cross-section. AA figure 1; figure 3 shows the remote element B of figure 2; figure 4 shows a view in figure 1 with mounted on the tower support block of weapons.

The tower of an armored military vehicle is a welded structure containing a bottom sheet 1 with a landing surface G, a frontal armored unit 2, side sheets 3, aft sheet 4 and a roof 5. On the roof 5, for mounting and fixing the support 6 of the weapon block, the landing surface D is made, emphasis E and holes J. Frontal armor unit 2 and support 6 of the weapon block are spaced on different sides from the axis of rotation of the tower.

The support 6 of the weapon block has a base 7 of thickness h, which is provided with threaded holes located coaxially with the holes J. The support 6 of the weapon block is placed with the back of the base 7 in contact with the stop E of the landing surface D of the roof 5, while the fastening elements of the support 6 of the weapon block, for example, bolts installed in the holes of the roof 5 with a gap. When fired, the recoil force P is perceived by the focus E, while the fastening elements, for example, bolts, remain unloaded from the shear load and work only in tension.

The seal between the support 6 of the weapon unit and the landing surface D of the tower is carried out by means of a rubber ring installed in the groove And made around the perimeter of the landing surface D.

To ensure the required strength of the stop E, its dimensions are determined from the ratios:

H = k · h;

M≥2H;

L> P / k · M · [σ],

where H is the height of the stop; M - stop width; k = 0.3 ... 1.0 - coefficient; h is the thickness of the base of the support 6 weapon block; L is the length of the stop; P is the maximum recoil force of the weapon; [σ] is the allowable stress of the roof material under cyclic loading. The length of the stop E can be made integral or consist of several parts.

The presence of a landing surface with an emphasis perceiving the recoil force on the roof of the tower makes it possible to make the frontal armor unit of the tower without embrasure holes that weaken the tower and, thereby, increase the armor resistance of the tower, and hence the survivability of the military machine as a whole. The possibility of using a removable support for the weapon block allows you to improve the maintainability of the tower, since there is no need for complex landing surfaces for installing a gun, which are difficult to recover from combat damage, and often can not be repaired.

The opportunity to place a support with a weapon block in the aft part of the tower is also advantageous in that it allows you to balance the heavy frontal armor site of the tower, that is, reduce the moment of turret unbalance and, thus, with the equal power of the turret rotation drive mechanisms, increase the turret rotation speed.

The proposed tower design provides reliable armor protection, high speed monitoring of the terrain and target designation, as well as reducing the number of combat damage leading to irreparable loss of the towers, simplicity and convenience of repair and restoration work.
