THRUST-PNEUMATIC PUSHER Russian patent published in 2009 - IPC B64G1/64 F42B15/36 

FIELD: space engineering.

SUBSTANCE: invention relates to space engineering and can be incorporated with the separation systems intended for jointing and separating space vehicles stages, for example for separating jettisonable stages of multi-stage carrier rockets. The proposed thrust-pneumatic pusher to separate space vehicle stages comprises a housing representing a tight hydraulic cylinder accommodating a rod, coupling units hinged to various parts of space vehicles and pyrotechnical lock. The latter has a bush furnished with a shoulder and a seat for rod end and a sleeve coupled with the pyrotechnical lock casing so as to allow the said shoulder to rest upon the cylinder end face. There are a shell interacting with the bush outer surface, a flexible split ring arranged between the bush shoulder, sleeve and nut fitted on the cylinder. The shell, in initial position, seats in side the said flexible split ring and is locked by easily deformable damper representing a sleeve arranged between the pyrotechnical lock casing and the shell. The said pyrotechnical casing is provided with seat intended for pyrocartridges furnished with channels to feed pyrogases to under the sleeve, and with union seat and channels to feed operating gas into the cylinder inner space.

EFFECT: expanded performances.
