IR-RADIATION PYRO ROUND Russian patent published in 2010 - IPC F42B5/08 F42B5/15 

FIELD: weapons and ammunition.

SUBSTANCE: proposed round comprises cartridge case accommodating functional grain closed by cover that rests on ring forming receiver above electric igniter that interacts with cartridge holder terminals on aircraft airframe. Said functional grain is arranged on screen membrane separating it from receiver. Output window of the cap with initiating charge is covered by gas-impermeable membrane while lower circular electrode is arranged on contact surface of the flange coaxial with central current lead and, via loading resistor, connected to its obturating flange isolated from top disk electrode. Proposed invention allows mechanical prevention of false closure of waste component electric circuit in its three-electrode igniter with separated connection in test and operating conditions.

EFFECT: higher reliability of aircraft anti-jam protection due to scheduled task of inner electric circuitry before use.
