Characterization of pyrotechnic composition used in tracer ammunitions

In this paper various pyrotechnic compositions used in VIS and IR tracer ammunition were studied to improve the required optical effect. These mixtures are designed to mark the direction of the bullet. The thermal behaviour of the compositions was determined by employing DTA tests. Additionally, spectral analysis and visual studies were used to assess the light output and radiant energy of the tracer combustion and establish the efficiency of the compositions. Since each well-known tracer blend that was tested needed optimisation, a new and improved configuration of VIS and IR composition was reported. Consequently, the optimal VIS and IR pyrotechnic mixture used in tracer ammunition was chosen based on their burn time, average luminous intensity and burning temperature.
