Head-on Interaction of Shock Fronts and Bow Waves of Re-Entry Vehicles

摘要

The report outlines in detail a method for calculating resultant shocks produced by head-on interaction of a shock front with the bow wave of a re-entry vehicle. The latest available equation of state for air data was used in calculating shock conditions for a number of altitudes, R/V velocities, and shock overpressures that are assumed to be of greatest interest in ABM problems. While the calculations described involve primarily a bow wave and a shock, the same methods apply to the head-on interaction of two planar shock fronts.
