Project of oxygen-kerosene rocket engine with rotor-pump unit

Expendable and Reusable Systems for Earth-to-Orbit Transportation

“…Rotor-type turbo pump unit feeding propellant into combustion chambers rotating on periphery of thee rotor can be used instead of conventional turbo pump unit [3] . Combustion products are accelerated (extended) after chambers in common nozzle block (such as expansion-deflection (E-D) annular nozzle).…”

“…There are modeling experimental and calculationtheoretical researches concerning this unit. They have shown, that slot-hole nozzles and nozzles blocks with the changeable area of exit area due to turn of modular liquid rocket engines [3,5] or sliding nozzles with the changeable area of exit area allow to realize close to full expansion of combustion products in an atmosphere and to obtain high value of a specific impulse at the high altitudes and in space. Annular (E-D) nozzles with central body also were considered.…”
