NOSE PROXIMITY FUSE FOR EXPLOSIVE-ACTION WEAPONS Russian patent published in 2012 - IPC F42C13/00 F42C19/00 

FIELD: weapons and ammunition.

SUBSTANCE: device includes the housing in which power supply, detonator, safety cocking mechanism, electronics unit connected to the above mechanism and target detector having at least two electrodes separated with electrical isolating insert being the part of the fuse housing is arranged. One of the electrodes, which is external, is made in the form of the part of fuse housing, and the other electrode, which is internal, is made in the form of body of rotation, mainly of flattened cone, and arranged inside the above insert; at that, thickness h of electrical insulating insert is according to the ratio: h≥1/10 L, where: L - length of generatrix of outer surface of head electrode in meridional section, and electronics unit includes detection device of variation of medium dielectric permeability in the detector sensitivity zone.

EFFECT: invention allows enlarging the application of fuses, providing proximity detonation of weapon at optimum distance from the target with high accuracy and increasing the stability of weapon to action of small-size interference.
