METHOD AND DEVICE FOR CREATING JET STREAMS WITH ELIMINATION OF HOLLOW CHARGE SPIN Russian patent published in 2013 - IPC F42B1/02 

FIELD: weapons and ammunition.

SUBSTANCE: jet recess represents a truncated cone surface coated with auxiliary facing of material with density exceeding that of explosive charge. Said facing is compressed and thrown by the charge detonation products onto outer surface. Jet facing is made of copper or its alloys, or refined iron. Jet stream generator consists in that auxiliary facing is connected by its one end closer to initiator with extra body. OD of extra facing vertex makes 0.26D and base diameter does not exceed 0.8D. Extra body diameter is not smaller than extra facing vertex OD at the joint point. Extra facing feature half-span internal angle β of 8 - 10 degrees and external angle β₁ of 8 - 13 degrees. Jet facing OD does not exceed 0.25D. Note here that internal angle of half-span β₂ makes 0 - 10 degrees, while external angle β₃ makes 0 - 12 degrees where D is jet charge OD. Extra facing base is conjugated with perforated diaphragm OD. Perforated diaphragm ID is conjugated with facing OD on the base side.

EFFECT: higher armor-piercing capacity.
