Description

 The invention relates to systems for protecting military vehicles from weapons of mass destruction and fire and can be used at objects of armored vehicles (tanks, infantry fighting vehicles, armored personnel carriers, etc.) equipped with a benzoelectric unit designed for consumers of electric energy with the engine idle (when the vehicle is stationary) )

 Known systems for protecting military vehicles from weapons of mass destruction, containing a gamma radiation sensor, temperature sensors, automation unit and engine stop mechanism. Such systems are installed on serial domestic tanks, infantry fighting vehicles and landings and have practically the same functional diagram. The purpose, device and principle of operation of these systems are detailed in the relevant manuals (see, for example, Tank T-2A. Technical description and operating instructions, Book 2 (part two) -M.: Military Publishing, 1989 - 368 pp. Open edition). In case of a nuclear explosion or fire inside the machine, the corresponding sensor generates an electrical signal that enters the automation unit (block B 11), which is activated and supplies voltage to the engine stop mechanism, which stops the fuel supply to the engine. At the same time as the engine, the generator stops, and consumers of electrical energy continue to be powered by batteries. After 30-50 s after the system is activated, necessary for the passage of a shock wave or to extinguish a fire, the automation unit relieves the voltage from the electromagnet to stop the engine and turns on the supercharger. After that, the driver must start the engine. At the same time, the generator will start working again, recharging the batteries and supplying consumers with electric energy.

 However, due to the fact that the failure of the crews from nuclear weapons is several times higher than the failure of military vehicles, especially tanks, during the fighting there will be situations when, after passing the shock wave, the engine of the operational machine will not be started, and consumers of electric energy ( armament stabilizer, supercharger, radio station, etc.) will be powered by rechargeable batteries, which will lead to their full discharge and, as a result, to reduce the combat readiness of the machine, as rechargeable batteries are duplicate, and in some cases the main means of starting the engine.

 Also known is the system for protecting military vehicles from weapons of mass destruction installed on command tanks (see, for example, Tank T-64 A. Technical description and operating instructions, Book 1 - MOP, 1973, - pp. 231-275. Prototype. Open Edition) and other BTT facilities (command-and-staff vehicles, etc.), with an installed benzoelectric unit (BEA). This system includes sensors, automation unit, engine stop mechanism; gas-electric unit, start button of the gas-electric unit. However, this system has low alert after exposure to weapons of mass destruction or fire.

 The objective of the present invention is to increase the combat readiness of a combat vehicle equipped with a gasoline-electric unit after exposure to weapons of mass destruction or fire.

 This task is achieved in that the system of protection of a combat vehicle with a gasoline-electric unit against weapons of mass destruction, comprising sensors that are connected to an automation unit, the first output of which is connected to a stop mechanism of the engine connected to the engine, the engine is mechanically connected to a generator, the output of which is the first the output of the benzoelectric unit is connected to the inputs of the batteries, the output of which through the fuses is connected to the consumers of electrical energy of the tank, between one of the inputs of the benzo-electric unit and rechargeable batteries, the start button of the benzo-electric unit is installed, it is equipped with a “Prohibition” logic element, a time relay and a contactor connected in series, the allowing input of the “Prohibition” element being connected to the second output of the automation unit, and the prohibiting input to the generator output, and the closing contacts contactors are connected parallel to the start button of the benzo-electric unit, and the second inhibit input of the "Prohibition" logic element is connected to the output of the benzo-electric unit.

 The invention is illustrated in the drawing, which shows the protection system of a combat vehicle with a gas-electric unit from weapons of mass destruction.

The drawing indicates:
1 - rechargeable batteries;
2 - generator;
3 - sensors;
4 - automation unit;
5 - engine stop mechanism;
6 - engine;
7 - logical element "Prohibition";
8 - time relay;
9 - contactor;
9-1 - closing contacts of the contactor;
10 - consumers of electric energy;
11 - a gasoline-electric unit;
12 - start button.

 The system works as follows. In a nuclear explosion or fire under the influence of gamma radiation acting on the sensors 3, these sensors generate a signal that enters the automation unit 4, which supplies voltage to the stop mechanism of the engine 5, the fuel supply to the engine 6 stops and it stops, and therefore, generator 2. Electric energy consumers continue to be powered by batteries 1. After 30-50 s, the automation unit 4 disconnects the voltage from the engine stop mechanism and at the same time gives a signal to trigger a logical element “Prohibition” 7, which in turn turns on the time relay 8. This relay, after the time required for reliable start of the engine of the machine, includes a contactor 9, which closes its contacts 9-1, connected in parallel with the start button 12. The gas-electric unit 11 starts and begins to recharge the batteries 1 and supply electrical energy to consumers 10. At the same time, the voltage generated by the BEA is supplied to the second inhibit input of the element "Prohibition" 7 and turns it off. Accordingly, the time relay 8 and contactor 9 are disconnected, the contacts 9-1 of which are opened, after which the starter mode of operation of the BEA is terminated. In the case of starting the motor 6 before the contactor 9 is activated, the voltage of the generator 2 retreats to the first inhibit input of the "Inhibit" element 7, which, when triggered, turns off the time relay 8.

 The use of a refueling system at BTT facilities containing BEAs will make it possible to increase their combat readiness after exposure to weapons of mass destruction or fire when crew members are out of order. This is ensured by the automatic start of the benzoelectric unit, which recharges the batteries and supplies the most important consumers with electric current.
