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.

MTV诱饵照明弹点火的研究

镁/聚四氟乙烯®/氟橡胶（MTV）照明弹是用于红外诱饵的烟火成分，用于保护空中目标免受红外制导导弹的攻击。在这项研究中，考察了配方变化对燃烧时间和达到所需红外辐射强度水平的时间的影响。点火，特别是使用的点火混合物的量和点火表面对测试参数有重大影响。对于密度为1.7g/cm3、质量约为40g的装药，在施加约5g的点火混合物后，可以获得所需的上升时间和辐射强度。在芯块的侧表面上具有点火混合物的凹槽面积与芯块的总侧表面的比率约为0.6。
