Reactive lighting cartridges of caliber 30, 40 and 50 mm, device, characteristics, operating principle and method of shooting.

Reactive lighting cartridges of caliber 30, 40 and 50 mm are intended to illuminate the terrain and targets at night immediately before the battle formations of their troops. They are finished shots. Their shooting is carried out without the use of special weapons or devices. 

Reactive lighting cartridges of caliber 30, 40 and 50 mm, device, characteristics, operating principle and method of shooting.

All reactive lighting cartridges are designed essentially the same. A powder charge is a source of rocket movement. It consists of a checker of nitroglycerin gunpowder, the combustion of which is provided by an igniter star, compressed from a special pyrotechnic composition.

The expulsion charge from the smoky gunpowder serves to ignite the illuminating star and to separate it from the reactive part. The lighting star consists of an aluminum shell, into which a special pyrotechnic lighting composition is pressed, which gives a large light intensity when burning.

30 mm reactive lighting cartridges, arrangement and purpose of constituent parts and elements.

The 30-mm reactive lighting cartridge consists of a launch tube, an igniter, a rocket and additional parts – a pressure tube, wad, cap and cap. The launch tube is used to accommodate the rocket and the ignition device. It directs the flight of the rocket and protects the cartridge parts from mechanical stress and moisture..

The starting tube consists of a cardboard sleeve with a metal base 7. On the bottom of the base there is a thread for screwing on the cap. The igniter is designed to ignite the powder charge. It consists of a metal cup into which an igniter capsule is inserted, which is a copper cap with a special friction sensitive composition.

A wire grater is passed through the igniter capsule. The upper end of the grater is twisted into a spiral. An extension cord of linen thread is tied to the lower end of the grater. The other end of the lanyard is attached to a metal ring. In the starting tube, the igniter is fixed with a cardboard stop.

The 30 mm rocket rocket launcher consists of a reactive part, an outburst charge and a lighting star. The reactive part is designed to inform the rocket of translational and rotational motion. It consists of a steel shell in which a plastic turbine and a powder charge are located.

The turbine has one central and three side openings (nozzles) designed for the release of powder gases from the reactive part. Side nozzles are made at an angle to the axis of the rocket. A powder charge is a source of rocket movement. It consists of a checker of nitroglycerin powder, the combustion of which is provided by an igniter star, compressed from a special pyrotechnic composition.

The expelling charge of the gunpowder of gunpowder serves to ignite the illumination star and to separate it from the reactive part. The lighting star consists of an aluminum shell, into which a special pyrotechnic lighting composition is pressed, which gives a large light intensity when burning.

Shooting reactive lighting cartridges, the principle of operation of cartridges during shooting.

For shooting, reactive lighting cartridges must be prepared: unscrew the cap, remove the ring with the extension cord from the socket. Then point the cartridge upward at an angle of 40–50 degrees and pull out the cord. In this case, the wire grater passing through the grater composition of the igniter capsule causes it to ignite.

A ray of flame penetrates the reactive part, ignites the stopped circle, an igniting star and a solid fuel checker. The gases formed during this flowing out through the nozzles of the turbine create a reactive force. A rocket under the influence of reactive force flies out of the launch tube and flies in a given direction. The launcher remains in the firing hand.

3-4 seconds after the shot, the ignition star burns out and ignites the expelling charge, which ignites the light star and separates it from the reactive part. When launching missiles at an angle of 40-50 degrees, the ignition of the lighting star occurs at a distance of about 250 meters from the point of shooting and at an altitude of about 150 meters.

During the first 1-2 seconds after separation, the illumination star flies forward and upward, reaching a height of 200-250 meters at a distance of 300-350 meters, then begins to decline. It burns out at a height of 30-50 meters and at a distance of 400-500 meters from the place of the shot.
