FIELD: physical researches. SUBSTANCE: accelerator has a casing formed with deformable walls covered with explosive charges with groups of electric detonators. The accelerator has an injector of jet generating material including a casing, formed with deformable walls covered with explosive charges. The walls became close to one another at the end opposite to jet receiver. Angle between the walls is not less than 90 At the other end the walls change slope to symmetry plane and become deformable walls of accelerator casing. A container with liquid jet-generating material is located at the apex of injector cavity. Jet-generating material viscosity should be less than one selected for wall material. A detonator is placed just opposite apex, where walls of the injector come together in the symmetry plane. Distance between electric detonator and deformable walls is shaped along casing length according to a proper relation. EFFECT: high-speed jet. 3 cl, 5 dwg
