Drag coefficients for bodies of meteorite-like shapes

The drag coefficients and the patterns of supersonic flows around rectangular parallelepipeds (bodies with rectangular and square faces-bricks and tiles, respectively) were found from numerical experiments. These drag coefficients c _x are considerably different from the values used, in particular, in the meteor-related literature to calculate the motion of brick-shaped meteor bodies. The values of c _x and the flow pattern near the face of the body weakly depend on the relative size of the body within the parameter range considered.
