Abstract
AbstractQuantitative assessment of the harmful phenomenon of medium and large‐caliber muzzle smoke provides crucial support for the development of advanced propellants. Based on the current maximum area method and integration method of transmittance curve of examining muzzle smoke, the Trace Analysis Model of Muzzle Smoke (TAMMS) is proposed. First, based on the characteristics of few mass exchanges and relatively fixed expansion center of muzzle smoke cloud formed by high‐pressure release with the slow‐release zone, a muzzle smoke characteristic quantity model refers to the area and the concentration corresponding to each other was established. Secondly, a test system was built to experimentally verify the smoke characteristic quantity model, and the test error analysis was carried out. The research results show that the Trace Analysis Model of Muzzle Smoke takes into account the relationship between smoke area and transmittance over time and can more ideally characterize the muzzle smoke volume. The results of parallel testing and analysis of 7 sets of traditional 35 mm guns show good reproducibility, with a measurement uncertainty less than 0.5 dB.
