Scientific paper

A numerical algorithm for solving the equation of motion in a coordinate system immobile relative to the earth is developed to estimate the influence of aerodynamic drag on space-time evolution and the separation of small man-made debris. The origin of this coordinate system coincides with the ejection source, the X-axis is the trajectory of vehicle motion, the Y-axis is perpendicular to the orbital plane, and the Z-axis is the radius-vector. Graphs illustrate the particle distribution in the XZ plane, and the distribution of engine ejection products (particles ranging from 1.5 to 10 mm in diameter) at 300 km in the orbital plane 100 s after the ejection in the direction of vehicle motion.
