CARRIER ROCKET ENGINE BUNDLE POWER UNIT Russian patent published in 2013 - IPC F02K9/88 

FIELD: engines and pumps.

SUBSTANCE: invention can be used primarily in carrier rocket power units for thrust vector control. Carrier rocket power unit with controlled thrust vector comprises tail compartment to house liquid-propellant sustainer engine and strong ring. Said compartment houses steering engine including four steering chambers that can swing in two mutually perpendicular planes. Blister is arranged on very steering chamber and rigidly jointed therewith in swinging assembly area. Note here that every steering chamber with blister is arranged on crossbar with thereon. Note that said crossbar is rigidly secured to strong ring to allow swinging of every chamber through common angle not smaller than 90ϵ. Said blister is composed of two rigidly interconnected hemispheres making a part of toroidal surface. Said crossbar is composed of two parts rigidly interconnected by split joint. Note here that flexible pipelines extending to combustion chamber are located inside tail compartment outside blister and crossbar coverage area to cross combustion chamber swinging axis to ensure combustion chamber swinging through common angle not smaller than 90°C. Note also that blister is furnished with external heat insulation while clearance between blister and crossbar is covered also with heat insulation.

EFFECT: efficient thrust vector control, better carrier rocket trueing characteristics, reliable protection of tail compartment against combustion products.
