RD-801

The RD-801 (Russian: РД-801) is an Ukrainian liquid propellant rocket engine burning LOX and Kerosene (RG-1) in a staged combustion cycle. It has a single combustion chambers that provide 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 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.

Versions

The designers have proposed three versions of this engine:

  • RD-801 (version 0) (Russian: РД-801 (исполнение 0)): This is the basic module with no TVC.
  • RD-801 (version 01) (Russian: РД-801 (исполнение 01)): This is a version which includes a TVC by gimbaling of the nozzle in two axis by +/- 6°.
  • RD-801V (Russian: РД-801В): High altitude of the rocket engine with extended nozzle.
