Motrichuk R. Improving the Fire Safety Of Pyrotechnic Flammators Based on Mixtures of Aluminum & Magnesium Powder Alloys and Nitrate-Containing Oxidizers

Pyrotechnic igniters are widely used to organize the process of combustion of multicomponent pyrotechnic mixtures, which are equipped with products for various purposes (lighting cartridges and artillery shells, photolight bombs, signal shells, etc.) used in the national economy and military equipment. In this case, the considered products in the process of circulation (storage, transportation and use) can be subjected to intense external thermal effects in various extreme situations (for example, in a fire in warehouses where tests are stored, in the conditions of their transportation during ignition of nearby objects, and also in the conditions of firing and flight of products during their launches, etc.), which leads to premature operation of charges of pyrotechnic igniters and flammable destruction of products, ignition of surrounding objects, human casualties, and causes significant material damage. Therefore, methods of preventing forced fire-hazardous destruction pyrotechnic igniters in the event of external thermal action are of practical importance. To develop such methods, it is necessary to have the results of theoretical and experimental studies of the processes of external heating, ignition and combustion development of compacted mixtures that form the basis of aircraft, with the definition of their explosive modes under different external conditions. At present, such studies are not available for the considered aircraft.
