The RD801 (Ukrainian: ) is a Ukrainian liquid propellant rocket engine burning LOX and Kerosene (RG-1) in a staged combustion cycle. 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.
The RD801 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 RD801 can be used stand alone on a Mayak or in a cluster.
Versions
The designers have proposed three versions of this engine: RD801 (Ukrainian: ): This is the basic module with no TVC. RD801 (Ukrainian: ): This is a version which includes a TVC by gimbaling of the nozzle in two axis by +/- 6°. RD801V (Ukrainian: ): High altitude of the rocket engine with extended nozzle.
