Description

ARMENIAN OBJECT FACILITY

The utility model relates to the field of armored structures, and specifically to the design of towers of objects of armored vehicles (MBT) and can be used to protect armored vehicles, such as tanks, silos, armored personnel carriers.

Currently cast towers in comparison with welded ones from rolled armor have a number of disadvantages:

-larger at 10 f 1b% weight

- less armor resistance.

Niches are made in the frontal part of the cast towers in the zones 52 58 ° relative to the longitudinal axis, for installing filler in them, for example, a sand rod, ceramic or rolled steel plates.

Known armor cap (see patent of Russia 2042917, P 41 H 7/02, 5/00, published 27.08.95), containing the main and external additional armor, where the main armor in the frontal part of the cap is made in the form of an inclined truncated cone, and additional the armor is fixed to the main one through bonoks.

A disadvantage of the known armor cap is that the proposed attachment of additional armor by means of bonks does not have the necessary survivability when hit by a cumulative or high-explosive fragmentation shell, because the area of support of additional armor only on bonks is extremely small.

Known armor protection, including an armor cap with mounted steel armor (see magazine..ietnationat Reviev / j

1988.T.U. No. 11, p.676). The proposed design enhances the protection of the armored object, but has several disadvantages, for example:

- unequal anti-projectile resistance along the height of the tower section due to a decrease in the inter-hail distance between the main and the outer

armor, increased mass of armored structures due to the extragional choice of armor thickness.

There are well-known turret tanks Ml and pLeopard-2 (see the journal Foreign military equipment, series Sh, 1978, No. 8, pp. 17-21 and series Sh, issue 23, pp. 8-9), on which the frontal part of the towers has niches formed by external and internal vertical armor plates. A niche is filled with material that additionally absorbs the energy of the attacking shell.

The disadvantages of the known towers is that the niches have a front wall that does not allow changing the internal volume of the niche.

In addition, the lack of inclination of the front wall does not create conditions for rebounding and increases the mass of the tower due to the irrational placement of the filler.

The purpose of the utility model is to increase the armor protection of the frontal projection of the tower by forming niches for additional protection.

This goal is achieved due to the fact that the vertical side walls of the niches are made at an angle relative to each other

about equal to 52 58, and the back wall of the niche is made inclined to the side

towers at an angle equal to 20 ° from the vertical, while the bottom wall is made in the form of a radially faceted prismatic supporting surface with an inclination downward at an angle equal to 9s-I2 ° from the horizontal plane and with an angle between adjacent faces equal to I77fI79 °.

The analysis of the main distinguishing features of the utility model and the beneficial effect obtained from them showed that:

the implementation of the vertical-side walls of the niche at an angle relative to each other equal to 52f58 ° provides when installing the filler in the niche, protecting the tower within the specified course angles of fire equal to ± 35 °;

- 2 - 3 the inclination of the rear wall of the niche towards the tower at an angle equal to the vertical allows reducing the volumetric weight characteristics of the tower to transfer the freed weight of the tower to a more impact-resistant filler, reducing the external radial dimension of the tower;

the lower radially faceted prismatic wall with an inclination downward at an angle equal to the horizontal plane allows not only to create ricochet conditions for an attacking projectile, but also to place a more impact-resistant filler on its inclined surface that reinforces the lower belt of the tower;

the angle of cut of the lower wall between adjacent faces equal to 177-179 °, allows you to place in the niche gapless and stepless filler in radius.

The utility model is illustrated by drawings, which show:

FIG. I - view of the tower in plan with niches, dash-dotted line

designated filler in niches;

FIG. 2 - section aa of figure 1;

FIG. 3 is a view B of FIG. 1;

FIG. 4 is a cross-section BB of FIG.

Tower I of the object of armored vehicles contains niches 2 made in its body, spaced relative to the longitudinal axis of the tower at an angle of 0 °, which is made equal to 26 30 ° (Fig. 1) for the installation of filler 3 (Fig. 1,2), where the dash-dotted line shows filler. The niche is formed vertically by the side walls 4, made at an angle b relative to each other equal to 52 t-58 ° (Fig. 1), which, when the filler 3 is installed in the niche, protects the tower within the specified course firing angles of ± 35 °. The rear wall 5 (Fig.1,2,3) of the niche is made inclined towards the tower, in the form of a flat thrust surface at an angle equal to 15 f 20 ° to the vertical.

The lower wall 6 (Fig.2,3,4) is made in the lead of a radially faceted prismatic supporting surface with an inclination downward at an angle e / equal to 9 - 12 ° from the horizon. The faces of the lower wall 6 are evenly distributed within the corner 6 forming a niche 2, and have an execution angle 6 of 177 f 179 ° between themselves in a vertical plane.

Job

When installing and holding, for example, by welding into a niche 2, the filler 3, the radially faceted lower wall b, unlike the flat one, allows the filler 3 to be installed radially gapless and stepless, completely filling the protected area in the corner b.

Due to the inclination of the lower wall b by an angle c) equal to 9 4-12, the weakened zone aa (Fig. 2) of the lower tower belt is reduced, because the angle c) corresponds to the angle of the ricochet of the projectile and allows the filler 3 to be mounted on the lower wall 6 of a more impact-resistant material than the tower itself, thereby strengthening zone a. The inclination of the back wall 5 by an angle equal to 15 f 20 ° from the vertical allows reducing the volumetric and weight characteristics of the tower I to transfer the freed weight of the tower to a more impact-resistant filler 3, reducing the external radial dimension of the tower in the zone of the angle Jo.

Thus, the proposed utility model Tower of an object of armored vehicles improves the protective properties of the frontal projections of the tower by forming niches for installing filler in them.
