Abstract

Characteristics of the field of application (equipment) The utility model is aimed at increasing the survivability of the BMP-2 infantry fighting vehicle (Fig. 1) in combat conditions by creating an additional oil supply for the lubrication system on each vehicle. The experience of military operations in the Republic of Afghanistan, the Chechen Republic, in the Persian Gulf zone and other military conflicts has confirmed that the units on infantry fighting vehicles BMP-2 often conducted independent operations in isolation from the main forces, confronted the enemy. The field of application (equipment) as part of combat units exposed to various types of enemy weapons requires bringing it to the necessary logical completeness, increasing survivability on the battlefield by using the device of the machine (left door fuel tank) for a different purpose. BMP-2 infantry fighting vehicles in case of damage to the lubrication system in any atypical situations of the 21st century wars, complete combat missions, save combat vehicles and personnel. Summary of the essence and technical result Characteristic of the essence of the result: in the BMP-2 infantry fighting vehicle there is a single oil tank with a capacity of 48 l (Fig. 2, pos. 1), pipelines (Fig. 2, pos. 2) are located in front of the power compartment of the vehicle . The oil tank is fastened with a tie strap to the starboard side of the machine, which is most often exposed to fire by the enemy. In addition, when the engine is running, the applied oil is constantly consumed (MT-16-P, MTZ-10P or M16IHP-Z), which averages 2.8 liters per 100 km of track. The minimum allowable amount of oil is 20 liters, if it is less than the established volume, it is not possible to operate the BMP-2 infantry fighting vehicle, respectively, the units will not perform the combat mission. Spare tanks for storing and transporting oil on an infantry fighting vehicle are not provided, therefore, in the course of operations in isolation from the main forces and equipment in case of damage to the oil tank and pipelines and, accordingly, oil leakage, refueling is not possible. Technical result to increase the survivability of an infantry fighting vehicle BMP -2 achieve that the utility model includes the use of a left door fuel tank with a capacity of 55 l (Fig. 2, item 3) out of 5 available fuel tanks with a total capacity of 462 l for storage, trans sorting and refueling the lubrication system as necessary in combat conditions. For stable operation of the utility model, it is proposed to disconnect the fuel wire (Fig. 2, pos. 4) from the door fuel tank (Fig. 2, pos. 3), to prevent fuel leakage from the remaining 4 tanks (Fig. 2, pos. 5 ) Close the fuel line fitting (Fig. 2, item 6) with a lock nut. Screw a bolt with a gasket of the corresponding diameter into the lower hole of the left door fuel tank (Fig. 2, item 7). Fill oil through the filler neck of the door tank (Fig. 2, item 8). The filler neck has a filter net for cleaning oil. To drain the oil, it is necessary to prepare the container (bucket) stored under the seat in the left landing compartment, unscrew the bolt (Fig. 2, pos. 9) or the cover (Fig. 2, pos. 10) designed to clean the tank, according to fill the container (bucket) with oil to close the openable hole. The technical solution guarantees increased survivability of the BMP-2 infantry fighting vehicle when performing combat missions in isolation from the main units.

Description

The technical field to which the utility model relates.

This utility model relates to the field of application of armored vehicles, namely the BMP-2 infantry fighting vehicle in combat operations in isolation from the main forces and assets of units and units. The utility model is aimed at increasing the survivability of the BMP-2 infantry fighting vehicle in combat conditions by creating an additional supply of oil for the engine lubrication system.

State of the art

From the existing level of technology, combat experience in the Republic of Afghanistan, the Chechen Republic, in the Persian Gulf and other military conflicts, the BMP-2 infantry fighting vehicle survivability model is known, which consisted of creating an oil supply for the engine lubrication system in tanks mounted on armor cars. The disadvantages of this solution are: inaccessibility to tanks during the enemy firing in the direction of the combat vehicle; easy destruction of tanks by the enemy; the limitations of firing a gun and coaxial machine gun with it.

The task to which the utility model is directed

The task the utility model aims to solve is to increase the survivability of an infantry fighting vehicle when performing combat missions in isolation from the main forces and assets of units and units.

This problem is solved due to the fact that the claimed device, which is an additional left aft door fuel tank with a capacity of 55 l, connected by fuel and drainage pipe wires with other 4 tanks, included in the fuel system of the BMP-2 infantry fighting vehicle, characterized in that it is disconnected from the fuel system, and is used to store and transport the oil of the machine’s lubrication system, which is used in case of damage to the system during the fighting.

Utility Model Disclosure

The essence of the utility model is that the BMP-2 infantry fighting vehicle has only one oil tank with a capacity of 48 l, the capacity of the entire engine lubrication system is 58 l, pipe wires are located in the front part, in the power compartment of the vehicle. The oil tank is attached to the starboard side of the car, which is most often affected by bullets and projectiles of the enemy. In addition, when the engine is running, the used oils (MT-16-P, MTZ-10P or M16IHP-3) are consumed in an amount of 2.8 liters per 100 km of track. The minimum allowable amount of oil is 20 liters. If there is less than 20 l of oil, the BMP-2 infantry fighting vehicle cannot be operated; accordingly, the units will not perform the combat mission, and the BMP-2 will be lost. Spare tanks for storing and transporting oil on an infantry fighting vehicle BMP-2 are not provided.

The utility model is illustrated by drawings that do not cover and, moreover, do not limit the entire scope of the claims of this technical solution, but are only illustrative materials of a particular case of execution:

The left door fuel tank (Fig. 1) is located in the aft part of the BMP-2 infantry fighting vehicle in the safest place. The essence of the utility model is illustrated in Figure 2. For stable operation of the utility model, it is necessary to disconnect the fuel wire (4) from the door fuel tank (3), to prevent fuel leakage from the remaining 4 tanks (5), close the fuel wire connector (6) with a lock nut. Screw a bolt with a gasket of the corresponding diameter into the lower hole of the left door fuel tank (7). Fill oil through the filler neck of the door tank (8). To drain the oil, it is necessary to prepare the container (bucket) available in the BMP-2, unscrew the bolt (9) or the cover (10) designed for cleaning the tank at the bottom, and close the opening to fill the container (bucket) with oil. If the oil tank (1), oil pipe wire (2) is damaged, they must be repaired.

Utility Model Implementation

It is advisable to represent the implementation of the utility model as ensuring the ability of units on infantry fighting vehicles BMP-2 in case of damage to the engine lubrication system when performing combat missions in difficult conditions by increasing survivability.

The technical solution guarantees increased survivability of the BMP-2 infantry fighting vehicle. If the oil tank and pipe wires of the engine lubrication system of the BMP-2 infantry fighting vehicle are damaged, the survivability of the vehicle increases significantly.

Claims (1)
