SHELL Russian patent published in 2009 - IPC F42B12/00 F42C11/06 

FIELD: weaponry.

SUBSTANCE: invention relates to shells with the fuse combined, contact and contactless operation. The proposed shell has fragmenting housing filled with explosive and fuse comprising detonator, safe-and-actuator mechanism and electronic unit connected power supply the consists of a receiver, clock signal generator and the following components connected in series, i.e. delay circuit, output gate connected directly to contact-type pickup, and electric igniter. The fuse is fitted in the shell head, while the electronic unit additionally comprises a sounding pulse radiator and AND circuit. Note here that the clock signal generator is connected with the sounding pulse radiator, delay circuit and one of the AND circuit outputs. The AND circuit output is connected to the receiver. Mind here that the AND circuit output is connected to the delay circuit input.

EFFECT: shell firing before contact with independent mediated control of shell approaching to fall surface irrespective of flight speed and time.
