Для подачи различных сигналов, позволяющих to establish a visual connection, including to determine your location in case of emergency situations, required evacuation, orientation and target designation, as well as in other cases, signal flares are used.
Types and characteristics
Among those produced at various enterprises and inthese or other countries, they differ in their capabilities, technical performance and tasks for which they are intended. Earlier, up to about the 80s of the last century, the most widespread were signal flares, made in the form of a special cartridge for the appropriate pistols, and also allowing for firing from smooth-bore hunting barrels. Later, they began to be displaced by devices made in the form of a cylindrical tube that did not require any weapon, and the launch in the vast majority of samples was provided directly from the hand. The signal flare device is fairly simple, but due to the need to make accurate calculations and knowledge of the pyrotechnic features of the substances used, it is not possible to make them in the living conditions with the required degree of reliability and safety.
Main parts of the rocket
Consider the basic elements of whichcomposed. First, it is the tube itself, in which all the component parts are placed. As a rule, it uses cardboard or plastic, which has the required qualities of mechanical strength, and in order to avoid dampness, it is coated with a waterproof lacquer.
At the bottom is screwedsealed lid pocket, which is a lanyard attached from the inside to a grater igniter. Immediately around the igniter there is an expelling charge, consisting of smoky or smokeless powder, and then a pyrotechnic composition follows through the gasket, which, after burning, provides an asterisk that is well visible from a long distance.
Making a rocket at home
Smoke flare is manufactured in the sameokay However, everybody is well aware of various ingredients that make it possible to produce a ground-based signal cartridge at home, which gives well-visible and dense smoke when heated.
Practical use
They launch signal flares, usually from the leftarms. Fingers firmly hold her body approximately in the middle, and the lanyard straightens with the right hand. After giving the device the required angle of elevation, which should be at least 35-40 degrees, with a sharp movement the cord is pulled out and the position of the cartridge should not change much in its direction. With particular care it is necessary to observe the rule of movement of the right hand. It should coincide with the center line of the device. If it is not observed, a missile departure can occur with the onset of possible negative consequences: from a ricochet to a fire, located near trees, buildings, etc.
Storage conditions
Сигнальные ракеты следует оберегать от попадания moisture, as this can lead to a failure of operation. In cases of water ingress on them, wipe them with a dry cloth, without disturbing the cartridge tightness. Do not expose them to direct exposure to sunlight as they may cause spontaneous combustion.
