Аннотация:In the case of multipoint initiation of the side surface of a cylindrical charge in a sectionperpendicular to the axis, a detonation wave with a complex gas-dynamic structure is formed,which has the shape of a polygon with vertices at wave conjugation points. The sides of the polygonare always convex toward the charge axis. It is stated that a smooth cylindrical detonationwave with reverse curvature can be obtained by using special devices at initiation points: lensesmade of an inert material. The dynamic characteristics of the material are experimentally determined,and the method for constructing the lens profile is substantiated. The operation of aninitiation node and the formation of a cylindrical detonation wave in a charge are mathematicallymodeled. The specific features of the operation of a single initiating node and a node that ispart of the experimental assembly are shown. The dynamics of axisymmetric compression by aconverging detonation wave is presented and compared with calculations.
