DETONATION COMMANDS RETARDER OF BALLISTIC TYPE Russian patent published in 2016 - IPC F42B3/16 

FIELD: aviation; weapons and ammunition.

SUBSTANCE: invention relates to systems of onboard pyroautomation of aircrafts and may be used in explosive devices. Retarder detonation commands of ballistic type comprises cylindrical housing with metal hammer-like piston, a propellant active charge and main passive charge of detonating explosive arranged on both sides of the striker, and initiating device for triggering detonation in the explosive substance. Propellant active charge is made in form of detonating extended charge piece and is arranged in pre-piston chamber of cylindrical case. Main passive charge is made in form of detonating extended charge piece in metal shell and arranged in behind-piston chamber of cylindrical body with formation of controlled gap between the ends of striker pin and main passive charge. Initiator is docked with propellant active charge and is in form of standard explosive, or fuse, or explosive device arranged outside the cylindrical case.

EFFECT: higher efficiency and reliability of onboard automation systems of aircrafts owing to formation of accurate time delays, required order of detonation commands and blocking false and unauthorised signals.
