• A hypervelocity impact with a rigid wall of a axisymmetric striker generating converging to the axis of symmetry shock wave (SW) is considered. An efficient method is proposed for calculation of the optimum shape of the striker and the corresponding optimal jetless flux, so that during all the interaction time the velocity of SW and velocity of movement of the beginning of contact of the striker with the rigid wall are equal. This realizes the so-called strong solution for the shock wave. In the example shown, the shape of the projectile is closed to conical, but unlike a cone the angle between the normal to the surface and the axis of symmetry decreases when moving from the periphery to the center.
