INFLATABLE DEVICE OF PASSIVE DECELERATION SYSTEM OF LAST STAGE OF LAUNCH VEHICLE Russian patent published in 2003 - IPC

FIELD: space engineering. SUBSTANCE: device includes container, developing mechanism and inflatable structure. Proposed device is made in form of autonomous monoblock rigidly secured on peripheral part adapter compartment of last stage of launch vehicle. Container is provided with spring-loaded doors engageable with swivel latches which are connected with locks-pushers of developing mechanism provided with pyro- hydraulic time relay engageable with locks-pushers. Units of developing mechanism are secured on outer side of container whose inner surface and surfaces of its doors are coated with elastic film secured to said surfaces over perimeter. Inflatable structure is made in form of set of spherical envelopes made from elastic polymer metallized film and enclosed in screen envelope which is secured to locking units found on container by means of lines. Lower rows of spherical envelopes are made from thicker film as compared with lower ones. EFFECT: simplified construction; enhanced reliability. 2 dwg
