liquid propellant rocket engine burning
LOX and
Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning " wax", and was re ...

staged combustion cycle
The staged combustion cycle (sometimes known as topping cycle, preburner cycle, or closed cycle) is a power cycle of a bipropellant rocket engine. In the staged combustion cycle, propellant flows through multiple combustion chambers, and is th ...

Versions
The designers have proposed three versions of this engine:
* RD-801 (version 0) (
Russian: ): This is the basic module with no
TVC.
* RD-801 (version 01) (
Russian: ): This is a version which includes a
TVC by
gimbaling of the nozzle in two axis by +/- 6°.
* RD-801V (
Russian: ): High altitude of the rocket engine with extended nozzle.
