METHOD FOR IMPROVING INTERFERENCE IMMUNITY OF NOSE PROXIMITY FUSE FOR EXPLOSIVE-ACTION WEAPONS Russian patent published in 2012 - IPC F42C13/00 F42C19/00 

FIELD: weapons and ammunition.

SUBSTANCE: method for improving interference immunity of nose proximity fuse for explosive-action weapons containing the housing in which there arranged is power supply, target detector connected to electronics unit and having at least two electrodes separated with dielectric insert consists in decrease of threshold of target detector sensitivity to small-size interference. One of the electrodes, which is external one, is made in the form of the part of fuse housing, and the other electrode, which is internal one, is made in the form of rotation body, mainly flattened cone, and arranged inside the above insert made from electrical insulating material for protection of target detector against action of small-size interference. Fuse fairing thickness h is determined from the ratio: h ≥ 1/10 L, where: L - length of generatrix of outer surface of head electrode in meridional section.

EFFECT: invention allows increasing the fuse resistance to action of small-size interference and enlarging the application of fuses.
