MODE OF TRANSFERRING A CHARGE ON A METALLIC BULLET Russian patent published in 2005 - IPC

FIELD: ballistics, namely to modes of transferring on a bullet of a charge, necessary for measuring its speed by mode of induced current; it may be used in criminal expertise and in trials of a developed weapon with metallic bullets.

SUBSTANCE: friction of a bullet which provides electrization occurs on dielectric surface of an oil film in the weapon's barrel at carrying out of a shot. For preservation of a charge on a bullet after its flying out of the barrel it is electrically isolated from metallic barrel with the same oil film. As for oil ensuring high level of a charge of the bullet transformer oil is proposed. The oil is introduced into the barrel in a quantity of several drops before shooting. For obtaining a stable and high magnitude of the charge second or third shots are made after introducing oil into the barrel.

EFFECT: increasing security and simplification of the mode.
