RU2811546C2 - Method for armouring diesel locomotive of special-purpose train of the railway troops - Google Patents

Abstract

FIELD: railway engineering.

SUBSTANCE: method for armouring aggregate units of a railway locomotive. The method is characterized by the fact that ultra-high molecular weight polyethylene (UHMWPE) was adopted as the basis for the locomotive armour material, from which a coating is created for large areas. UHMWPE coating covers all the necessary structural elements of the locomotive and fastens them with belts also made of UHMWPE.

EFFECT: efficient protection of the locomotive and the crew of a special-purpose train against potential enemy attacks.

Description

The claimed invention relates to the field of transport engineering and can be used for armoring locomotive components, and mainly the driver's cabin of existing shunting locomotives made of ultra-high molecular weight polyethylene (UHMWPE), as well as locomotives of other series and cars included in special trains designed to perform tasks to accompany military trains and carry out restoration work at railway transport facilities in emergency situations and armed conflicts.

There is a known method for manufacturing an armored car cabin from composite materials and an armored car cabin from polymer composite materials (patent RU2 494 407). This invention is mainly intended for creating structures and special-purpose elements and cannot be used to armor a diesel locomotive without changing its design.

The invention (patent RU2 486 430) presents an element of vehicle armor protection that prevents a bullet or fragment of an explosive device from penetrating into the passenger compartment. The armor protection element is at least one armor plate attached to one or more armor protection elements. The disadvantage of this design is the use of armor plates, which are heavy and make it impossible to quickly install (dismantle) them on a diesel locomotive.

The invention (patent - RU2 502 037) presents a variant of hidden vehicle armor, which contains an armored capsule welded from armor panels. The disadvantage of this invention is the presence of an armored capsule, which is also not intended for operational installation, has a large mass, and is also a complex design when armoring a diesel locomotive.

In the utility model (patent No. 124380), the structure contains a front armored wall, rear, side, upper armored panels and flooring, interconnected to form a sealed housing of a rigid structure. The proposed design provides protection for personnel from small arms fire, which is located directly in the vehicle cabin, but does not protect personnel and cargo transported in the back.

The utility model (RU133 601U1) is distinguished by the fact that the panels are made of single-layer fine-pored aluminum and are installed on a special frame using roller supports in an open or tented car body, which ensures their mobility and quick dismantling. The armor panel with roller supports is installed on the frame guide rails. The panel is made of dispersed fine-porous aluminum with a closed pore structure. Aimed at creating quickly dismountable armor protection with high ballistic resistance and a lightweight design for sheltering passengers and cargo transported in the back of a vehicle during movement and during disembarkation (unloading).

As a disadvantage, it should be noted the complexity of the design, the need to have a frame base, which must be pre-installed.

The presented method of armoring a shunting diesel locomotive with ultra-high molecular weight polyethylene (UHMWPE) is intended to protect the aggregate components of the locomotive and the locomotive driver's cabin from fragmentation and small arms fire.

The main technical features of the presented technical solution include the unique properties of UHMWPE, such as wear resistance, high impact resistance and damping properties, high values of impact strength and impact strength, resistance to abrasive wear and cuts; frost resistance; low creep.

Unlike metal armor, polyethylene is absolutely insensitive to angles of interaction, which means that its resistance is almost the same when hit by a fragment or bullet both normal to the obstacle and at large angles.

For this kind of material, there is no need to make changes to the design of the locomotive in the form of additional brackets or technological holes, because it is possible to create a coating of a large area that will cover all the necessary structural elements.

This armor is secured with special belts, which are also made of UHMWPE.

Thus, the use of the proposed method of armoring a TEM18DM diesel locomotive with ultra-high molecular weight polyethylene (UHMWPE) will ensure effective protection of the locomotive and a team of special train drivers from possible enemy influences.

The invention is illustrated in figures 1 and 2.

Figure 1 shows a general view of a shunting diesel locomotive with ultra-high molecular weight armor (UHMWPE) applied to it.

Figure 2 shows the main elements of armoring a diesel locomotive with ultra-high molecular weight armor (UHMWPE):

pos. 1 - tie belt;

pos. 2 - rear (front) wall of the locomotive body;

pos. 3 - end wall of the locomotive body (2 pcs.);

pos. 4 - end wall of the driver’s cabin (2 pcs.);

pos. 5 - rear (front) wall of the driver’s cabin (2 pcs.).
