Effect of Shot Duration on the Firing Accuracy when Burst Fire of Unguided Rockets

摘要

The paper introduces an analysis of multiple rocket launcher oscillation during fire of an unguided rocket set. It contains built mathematic model of a launcher including oscillation as well as model of unguided rocket motion. The effect of a variable time delay between two consequent launches and its impact on a launcher oscillation is analysed. The BM-21 (Russia) multiple rocket launcher system with corresponding 9M22U unguided rockets have been used for the model simulation and experimental verification. The results are used for assessment of launcher stability and oscillation during fire. The model simulation results are very close to the experimental results.
