Description

The utility model relates to military equipment, namely to ammunition, in particular to sub-caliber shells with a detachable ring air intake with an obturating belt.

The proposed projectile relates to armor-piercing firing under-caliber projectiles (BPS), designed for existing artillery weapons, which are equipped with modern tanks, its dimensions should not exceed the capabilities of automatic charging devices.

Known armor-piercing feathered subcaliber projectile ("Means of destruction and ammunition", Publishing house of MSTU named after NE Bauman, p. 587). It contains a housing with a ballistic tip fixed to it, mounted by a sector master device, fastened by sliding rings forming a centering base. The front of the supports, placed towards the ballistic tip, is made in the form of pylons. An annular air intake is made on the rear centering support; a feather stabilizer is located in the rear part of the housing.

In the specified device there are drawbacks - rebound and shallow penetration depth of homogeneous armor, which are completely eliminated in the proposed utility model.

In addition, the armor-piercing feathered subcaliber projectile is known ("Means of destruction and ammunition", Publishing House of MGTU named after NE Bauman, ZBM-42 "MANGO", p. 587), which is a prototype of the proposed utility model, containing a tracer, feather stabilizer, housing , annular air intake with obturating belt, shaft, armor-piercing tip, ballistic tip.

However, this shell has the following disadvantages: insufficient penetration depth of homogeneous armor and a high probability of rebound.

The objective (technical result) of the proposed device is to increase the penetration depth of a homogeneous armor and reduce the likelihood of a rebound.

The task is achieved by the fact that in the known armor-piercing firing projectile projectile containing a tracer, a feather stabilizer, a housing, an annular air intake with an obturating belt, a rod, an armor-piercing tip, a ballistic tip, an armor-piercing tip is made in the form of a truncated cone with grooves along the semicircular shape of the surface.

On (Fig. 1) shows a structural diagram of the proposed BPS. In (Fig. 2) shows a diagram of an armor-piercing tip.

The proposed projectile (Fig. 1) contains 1 - tracer, 2 - feather stabilizer, 3 - body, 4 - annular air intake with obturating belt, 5 - armor-piercing tip, 6 - ballistic tip, 7 - rod.

The projectile works as follows: when the projectile leaves the bore under the action of an incoming air flow, the annular air intakes 4 create a lifting force on the host device, then smoothly move away from the projectile body without affecting it or the plumage 1. Without kinetic energy loss due to nutational vibrations the shell of the shell reaches the target. When a projectile collides with armor, the ballistic tip collapses, and the armor-piercing tip in the form of a truncated cone with grooves along the semicircular shaped surface contributes to penetration of the armor by reducing the cross-sectional area of the armor-piercing tip, as well as the side faces of the grooves, which act as cutting edges, which when in contact with armor at an angle to the normal contribute to the "bite" of the body on the armor. Incision of the edges of the grooves reduces the likelihood of re-stripping. The number and size of the grooves are selected from the condition of reducing the cross-sectional area of the tip by 25-20%. Also, a star-shaped striker (Fig. 2) contributes to an increase in the penetration depth compared to the standard tip (Fig. 2) due to a decrease in the penetration energy. This is realized due to the fact that the deformation of the armor material propagates radially and tangentially due to its shape as a striker.

или обедненного уран

).The technical result is to increase the penetration of the homogeneous armor of the BPS due to the armor-piercing tip, made in the form of a truncated cone with grooves along the forming surface of a semicircular shape (Fig. 2). The increase in penetration is due to the fact that the cross-sectional area of the head of the star-shaped projectile is smaller compared to the standard armor-piercing tip. Also, the deformation of the armor material for a star-shaped projectile is distributed radially and tangentially, and because of this, the energy spent on breaking through is less. The edges of the grooves located on the tip contribute to the occurrence of the cutting process and reduce the likelihood of re-scraping. Due to the fact that the tip is made of medium carbon

steel, it will facilitate the penetration of the rod (VNZh-90 rod material

or depleted uranium

)
