Numerical simulation of shock wave processes at rocket explosion at launch position or in flight

摘要

The two-dimensional gas dynamic problem concerning the rocket explosion in the launch position and during the active flight leg is solved. The shock wave stage of the process, accompanying the explosion, has been studied using the numerical simulation. Space and time distribution of the gas dynamic functions after the explosion is determined, and also the center-of-mass trajectory of the exploded rocket is estimated and initial data are formulated for solving the problem of the creation and dynamics of the fire ball, which is necessary to develop the emergency system of cosmonauts rescue.
