Abstract
The compression and fracture of the propellant charge under the corresponding charge structure is the fundamental cause of the chamber explosion. Determining the degree of fragmentation of the propellant charge is an important research content for evaluating the launch safety of propellant charge. The initial dynamic vivacity ratio of propellant charge as a key parameter to quantitatively characterize the fragmentation degree of the bottom propellant charge, which is the core of the launch safety evaluation of the propellant charge. Based on the theory of initial dynamic vivacity ratio, combined with the actual situation of the experiment and the simulation results, the factors affecting the accuracy of the initial dynamic vivacity ratio of the fitting interval and the experimental drug weighing error are analyzed in this paper. The results show that when the charge weighing error has little effect on the test results of the initial dynamic vivacity ratio. Meanwhile, when the cut-off interval is the part where the dynamic vivacity ratio is greater than 1, the initial dynamic vivacity ratio is closest to the real situation.
