The article considers an engineering simulation method to calculate the ballistic limit
depending on the double wall at the high-speed collision, which can be used in assessing
space vehicles structural elements stability under the man-made meteor particles influ-
ence, looks at the method calculations results for two model variants equivalent to space-
craft design standard elements. We selected as models the fuel tank fragments with pro-
tection and a radiator cross-section with the built-in thermal tube, analyzed the proposed
method application at increasing the bumper wall thickness for the fuel tank design that
gave a positive result. The article shows various approaches validity while assessing
spacecraft risks from the space debris or meteoroid impact damage - impact testing ex-
perimental results, numerical and engineering techniques.
Keywords: ballistic equation, high-speed collision, spacecraft, screen protection, experi-
mental studies, numerical modeling.
