Calculation of Overall Effective Extinction Cross Section of Several Cold Smoke Infrared Ammunitions

摘要

The effective extinction cross section is an important parameter of the cold smoke infrared ammunition. This paper discusses the calculation of the maximal effective extinction cross section of the smoke produced by several smoke ammunitions and gives the optimal distance between the centres of the two adjacent smoke spheres. This study can provide theoretical basis for proper use of the smoke ammunition and the optimisation of the discharger.
