DEVICE TO RESTRICT EFFECTS OF EXPLOSIVE OBJECT BLASTING ABOARD AIRCRAFT Russian patent published in 2010 - IPC F42B39/00 

FIELD: transport.

SUBSTANCE: proposed device comprises housing made up of aligned outer and inner load cylindrical bearing chambers. Note here that inner chamber has at least two-layer wall. Note that inner wall face walls feature thickness notably smaller than that of outer chamber wall. Inner chamber has opening to accommodate explosive object into inner chamber as close to its axis as possible. Split inner chamber has its upper part that can move toward said opening and one of its face walls that can move along chamber axis to make said opening communicate with inner chamber space. Inner chamber is made elongated so that is face walls are represented by aircraft airframe sealed part detachable elements. There is structural access door to allow access into inner load bearing chamber.

EFFECT: higher flight safety thanks to ruling out emergency in unauthorised blast.
