The RD-801 ( Russian: РД-801) is a Ukrainian liquid propellant rocket engine burning LOX and Kerosene ( RG-1) in a staged combustion cycle. [4] It has a single combustion chamber that provides thrust vector control by gimbaling of the nozzle in two axis by +/- 6°. It is being designed in Ukraine by Yuzhnoye Design Bureau for the prospective first stage propulsion of the Mayak rocket family. [4] [2]
The RD-801 as well as the RD-810 are being designed based on the work of the RD-8 vernier and the maintenance and improvement of the RD-120 engines. The RD-801 can be used stand alone on a Mayak or in a cluster. [2]
The designers have proposed three versions of this engine:
