RU159266U1 - DEVICE FOR PROTECTING THE CARRIER'S CARRIER CREW FROM NUCLEAR EXPLOSION AIR SHOCK WAVE - Google Patents

Abstract

A combat vehicle containing inhabited compartments, characterized in that it is equipped with a device for protecting the crew from an air shock wave of a nuclear explosion, which is a bolt wedge that closes the barrel channel that goes into the inhabited compartments, the bolt wedge is connected to the axis of the re-platoon mechanism, which interacts with the executive an element receiving a signal from a gamma radiation detector of a nuclear explosion.

Description

The utility model relates to the field of military equipment, in particular to devices for reducing the impact of an air shock wave of a nuclear explosion on the crew of samples of armored weapons.

Known devices for protecting the crew of combat vehicles from an air shock wave of a nuclear explosion, in which protection is carried out by special sealing devices installed on the machine, some of which constantly seal the inhabited compartment, others are closed automatically by the signal of the radiation and chemical reconnaissance device (PRXR), and automatic engine stop (see. Technical description landing combat vehicle (BMD-1) Military Publishing House of the Ministry of Defense of the USSR 1973, p. 379. Open edition).

In addition, a device is known for protecting the crew of combat vehicles from an air shock wave of a nuclear explosion, for the T-72A tank, which consists in the following: by the signal of the PRXR equipment, the following are closed: valves of exhaust fans of the hull and turret; blower air intake valves and dust discharge ducts; air intake valve; the filter-absorber is switched on by moving the valve from a lower position to an upper one; exhaust fans in the hull and tower stop; the supercharger is turned off; the electric drive of the horizontal guidance tower is turned off and the engine stops (see Technical description and operating instructions for the T-72A tank, book two (part two). Military Publishing House of the USSR Ministry of Defense 1989, p. 396. Open edition. Prototype).

The known device for protecting the crew of combat vehicles from an air shock wave of a nuclear explosion can partially reduce the effect of excess pressure in the front of the shock wave of a nuclear explosion on the crew and internal equipment of the machine. However, in the process of combat activity with a probability of 0.1-0.3, such a mode of sealing the inhabited compartments can take place when the artillery shutter wedge is in the open position and there is no shot in the barrel channel. This mode of sealing is observed during the search for targets on the battlefield, the choice of ammunition and the preparation of data for firing. In this case, the specified protection device does not allow to completely seal the inhabited compartments before the arrival of the shock front, and to ensure a safe pressure in the inhabited compartments when the wave flows through the barrel of the artillery system, and also to reduce the noise impact on crew members.

The objective of this utility model is to ensure complete sealing of the inhabited compartments by automatically closing the channel of the gun barrel with a bolt wedge before the front of the air shock wave arrives, to eliminate a sharp increase in pressure in the inhabited compartments due to air flowing through the channel of the gun barrel.

The technical result of the proposed utility model is to reduce the likelihood of machine crew failure due to the use of an automatic, high-speed system for closing the channel of the gun barrel before the front of the shock wave of a nuclear explosion arrives at the machine.

The technical solution of the proposed utility model is the transmission of a signal to the actuator, which provides a quick closure of the channel of the barrel of the gun with a wedge bolt in conditions of use of nuclear weapons.

A combat vehicle containing inhabited compartments, characterized in that it is equipped with a device for protecting the crew from an air shock wave of a nuclear explosion, which is a bolt wedge that closes the barrel channel that goes into the inhabited compartments, the bolt wedge is connected to the axis of the re-platoon mechanism, which interacts with the executive an element receiving a signal from a gamma radiation detector of a nuclear explosion.

.A utility model is illustrated in FIG. 1, which shows the device for protecting the crew of combat vehicles from an air shock wave of a nuclear explosion, where: 1 - sensor; 2 - electric wires; 3 - an executive element (an electromagnet with a rod); 4 - axis of the re-platoon mechanism; 5 - shutter wedge; 6 - trunk channel; 7 - inhabited offices. The figure also shows two positions of the shutter wedge: 1 position - the open position of the shutter wedge before the explosion, indicated by a straight line

, 2 position - the closed position of the shutter wedge during the explosion, indicated by a dotted line

.

Sensor 1 is designed to detect powerful gamma radiation from a nuclear explosion, connected to an actuating element (an electromagnet with a rod) 3 by electric wires 2, transmits a signal to it until the shock front arrives. The actuating element 3 is designed to convert an electrical signal transmitted through electric wires 2 into the translational motion of the actuator rod 3, acting on the axis of the re-cocking mechanism 4 mechanically connected to the bolt wedge 5 which closes the bore 6, sealing the habitable compartments 7. The wedge travels from position 1 to position 2, as shown in FIG. 1. After the front of the air shock wave passes, the crew member manually performs actions to open the bolt wedge.

An example of the operation of the device. The sensor 1 transmits a signal to the actuating element 3 via electric wires 2. The actuating element 3 acts on the axis of the re-cocking mechanism 4, mechanically connected with the wedge of the bolt 5, which moves and closes the bore 6, the living compartments 7 are sealed.

The proposed device allows you to protect the crew of the machine from a sharp increase in pressure in the inhabited compartments when exposed to excess pressure in the front of the shock wave of a nuclear explosion, to ensure quick, automatic closing of the barrel, thereby increasing the degree of tightness of the inhabited compartments and the combat readiness of the crew.
