DEVICE FOR RESCUE OF CYLINDRICAL MODULE FROM SUBMARINE STATION TO WATER SURFACE Russian patent published in 2011 - IPC B63G8/40 B63G8/41 B60J7/02 

FIELD: transport.

SUBSTANCE: invention relates to rescuing of submarine crew. Device comprises launching tube with cover that has radially slack sections. Tube accommodates high-temperature gas generators (~2500 K) arranged along the cover edges. Said launching tube houses cylindrical module with sharpened hose cone and circular cavitator, and gas ring arranged between module cylindrical surface and launching tube inner surface. Space between gas ring and launching tube cover is communicated with pressure source. Outlets of high-temperature gas generators are integrated by annular receiver accommodating outlet nozzles arranged along its edges and directed upward at α=0…25° to tube lengthwise axis. Cavitator is made from angles with sharpened front edge that represent half-rings that may be separated by, for example, two pyro pushers connected to control system. Distance from nose cone edge to cavitator mounting plane equals L=0.5…1.1 D. Cavitator ring width is δ=0.01…0.02 D, where D is cylindrical module diametre. Pressure source is made up of low-temperature gas generators (~500 K) connected to control system.

EFFECT: higher reliability of rescue operation thanks to ruling out underwater streams action of module.
