RESCUE DEVICE Russian patent published in 2015 - IPC B64D1/14 

FIELD: aircraft engineering.

SUBSTANCE: proposed method is implemented by damping of the bottom at landing and softening of side impacts by extending parts of sidewall crimps. Device comprises bottom (1), sidewall (2) folding and unfolding in vertical direction, slings (3), and bearing carcass (5) with protective roof (6). Sidewall is composed of flexible bellow (7) enveloping said bottom and tightly secured thereat to make top chamber (8) to house objects to be salvaged and bottom damper chamber (9) filled with compressed air. Note here the check valve is fitted in flexible bellow of the latter and provided with throttle composed of pipe fitted between crimps of flexible bellow. Said side wall composed of flexible bellow adds to reliability owing to decrease in abrasion of material at folding/unfolding.

EFFECT: higher safety.
