Electrical method and apparatus for impelling the extruded ejection of high-velocity material jets

Patent ·
OSTI ID:5559992
This patent describes an apparatus for producing a high- velocity material jet, the apparatus adapted to be driven by an externally supplied electric current pulse. The apparatus comprising: a coaxial two-conductor transmission line that comprises an outer cylindrical conductor, an inner cylindrical conductor that has a common central axis therewith, and a solid plastic or ceramic insulator that completely fills the space between the inner cylindrical conductor and the outer cylindrical conductor. The transmission line having a first end and a second end. The outer cylindrical conductor and the inner cylindrical conductor at the first end of the transmission line adapted to receive the externally supplied electric current pulse; and a thin-walled metal structure attached or bonded to the solid plastic or ceramic insulator and conductively joining the outer conductor to the inner conductor at the second end of the transmission line, with the metal structure axisymmetric with respect to the common central axis and having a cavity that opens inwardly toward the interior of the transmission line.
