Abstract
The streamlining density fields for elongated models of explosion-formed projectiles were studied by the interference method. The character of the density profiles and their variation upon increasing the Mach number from M=3 to 4 are considered. The analysis reveals some special features in the stabilization shock wave formation. It is shown that the proposed model shape is admissible from the standpoint of moderate aerodynamic resistance and sufficiently high stability.
