NUCLEAR SUBMARINE AND MARINE-VERSION ROCKET ENGINE Russian patent published in 2012 - IPC B63G8/00 F02K9/48 

FIELD: transport.

SUBSTANCE: set of invention relates to ship building, particularly, nuclear submarines. Proposed submarine comprises fast hull enveloping light hull, tanks arranged between said hulls, fast con and rescue surfacing chamber arranged inside fast hull under fast con, and, at least, one nuclear reactor connected via circulation circuit pipelines with turbogenerator electrically connected with motor. At least, one streamlined tight pod with fast-detach face plug housing liquid-propellant rocket engine. The latter comprises airframe, combustion chamber suspended to airframe and having cylinder part and nozzle, gas generator and turbo pump unit including, in its turn, turbine, oxidiser and fuel pumps, gas duct communicating turbine outlet with combustion chamber head via suspension assy. Careen nozzles are arranged in pairs on load-bearing ring fitted on light hull outer surface cross-section. Generated gas feed pipeline and fuel feed pipeline are connected via gas and fuel three-way valves to careen nozzles. Opposite end of generated gas feed pipeline is connected with gas bleed pipeline. Careen nozzles are secured on load-bearing ring by means of two inclined tie rods.

EFFECT: notably higher speed in attach on surface, better controllability.
