METHOD OF TRIGGERING A POINT PROXIMITY FUSE Russian patent published in 2012 - IPC F42C13/00 F42C19/00 

FIELD: arms manufacturing.

SUBSTANCE: method of triggering a fuse containing a casing housing a target detector connected to the electronics module and equipped with at least two electrodes divided by a dielectric insert is based on target detection and is associated with an alteration of dielectric conductivity of the environment the sensitive area of the sensor. The sensitive area of the target sensor is previously adjusted according to the dielectric conductivity of the environment, protecting the target sensor from interference by choosing the correct thickness of the ammunition shroud made of electroinsulating material. The ammunition is accelerated, then the electronics module is energized thus inducing the sensor's input capacity alteration by changing the dielectric conductivity of the environment in the sensitive area of the sensor and the blasting impulse is formed. The thickness of the ammunition shroud h is established based on the ratio: h ≥ 1/10 L, where: L - length of the external surface element of the point electrode in the meridian section.

EFFECT: enhanced fuse application, provision of triggering a proximity fuse at the optimum distance from the target with high precision alongside with enhanced fuse resistance to mini-interferences.
