Abstract
Mg/Teflon®/Viton (MTV) flares are the pyrotechnic compositions used in infrared decoys to protect aerial targets from IR-guided missiles. In this study, the influence of formulation changes on the burning time, and on the time to reach the required level of intensity of infrared radiation was examined. An ignition, in particular the quantity of ignition mixture used, and the ignition surface has a significant influence on the tested parameters. For charges with a density of 1.7 g/cm3 and a mass of approx. 40 g, it was possible to obtain the required rise time and intensity of radiation after applying about 5 g of the igniting mixture. The ratio of the grooved area, with the ignition mixture on the lateral surface of the pellet, to the total lateral surface of the pellet was approx. 0.6.
期刊介绍：
CEJEM – the newest in Europe scientific journal on energetic materials It provides a forum for scientists interested in the exchange of practical and theoretical knowledge concerning energetic materials: propellants, explosives and pyrotechnics. The journal focuses in particular on the latest results of research on various problems of energetic materials.
Topics:
ignition, combustion and detonation phenomenon;
formulation, synthesis and processing;
analysis and thermal decomposition;
toxicological, environmental and safety aspects of energetic materials production, application, utilization and demilitarization;
molecular orbital calculations;
detonation properties and ballistics;
biotechnology and hazards testing
CEJEM presents original research and interesting reviews. Contributions are from experts in chemistry, physics and engineering from leading research centers in Europe, America and Asia. All submissions are independently refereed by Editorial Board members and by external referees chosen on international basis.
