SAFETY DEVICE FOR AIRCRAFT ONBOARD AUTOMATICS DETONATION CIRCUITS Russian patent published in 2015 - IPC F42C15/00 F42C15/184 F42C15/40 F42C15/42 

FIELD: aircraft engineering.

SUBSTANCE: proposed device comprises case with through cylindrical bore stopped by pressure cover from one side and by end plug with internal piston from opposite side. Transfer detonator charge features U-like shape and is composed of two radial channels in the piston body and axial channel communicating the later and accommodating explosive composition embedded and/or fitted therein. Booster charges are arranged on both ends of transfer charge. One boss of the device case accommodates electric fuse and transfer charge end device for transfer of detonation commands while cotter pin is fitted in another boss. Retainer is fitted in through holes made in the walls of the case and piston to retain both by pre-compressed cylindrical spring fitted in piston blind chamber on piston one side. Spacing between electric fuse and transfer charge end element complies with that between radial channels of said charge. End plug to be screwed in device case serves to adjust the piston stroke.

EFFECT: higher reliability, multi-purpose applications, simplified design, better manufacturability, reusable feature.
