Ground signal cartridges of red, green, yellow lights and orange smoke are used to indicate the front line and the lines occupied by the troops, command posts, firing positions, as well as span strips for aviation.
Ground signal cartridges of red, green, yellow lights and orange smoke, device and principle of operation.
Ground signal cartridges of red, green and yellow lights consist of a paper case, a signal star, an igniter, a cover with a ring and handles with a holder.
The housing serves to accommodate the signal sprocket and igniter and to protect them from mechanical stress and moisture. The outer surface of the housing is painted with a protective color. The signal star gives a red, or green, or yellow light when burning. It consists of a checker, pressed from a pyrotechnic composition, and a paper shell.
Main technical characteristics of ground signal cartridges of red, green, yellow lights and orange smoke.
The igniter is used to ignite the signal star. It consists of a grater primer with a grater fixed in a plastic diaphragm, and an extension cord with a button attached to the grater. Igniter capsule, grater and cord are the same as 30 and 40 mm reactive lighting cartridges.
The diaphragm has four openings through which, under the action of the cartridge, combustion products of the signal star exit from the housing. A metal cover closes the cartridge from above and protects its equipment from mechanical stress and moisture.
The ring attached to the cover is designed to be removed when preparing the cartridge for action. When pulling the cord, the friction of the grater on the grater composition ignites the igniter capsule. A beam of flame from the capsule ignites the signal star. When a signal star burns, a red (green or yellow) flame is formed.
Orange smoke ground signals, device and principle of operation.
Ground smoke orange ammunition cartridges consist of a paper case, two igniter tablets, two smoke bombs, an igniter device and a cap with a ring. The case, igniter and cover with a ring are arranged similarly to the corresponding parts of the ground signal cartridge of red, green or yellow fire and are intended for the same purposes..
Smoke bombs are pressed from a special pyrotechnic composition and give orange smoke when burning. Ignition tablets are designed to improve the ignition of smoke bombs. They are made of pyrotechnic composition and smoky gunpowder.
When jerking behind the exhaust cord, the igniter caps ignites. A beam of flame from the capsule ignites the tablets, which in turn ignite the smoke bombs. During the burning of the pieces, orange smoke is formed, which, through the holes in the diaphragm, leaves the cartridge case.
Based on the book Explosives and gunpowder.
