The RD801 (Ukrainian: РД801) 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 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.[2]
Versions
[edit]The designers have proposed three versions of this engine:
- RD801 (Ukrainian: РД801): This is the basic module with no TVC.[2]
- RD801 (Ukrainian: РД801): This is a version which includes a TVC by gimbaling of the nozzle in two axis by +/- 6°.[2]
- RD801V (Ukrainian: РД801В): High altitude of the rocket engine with extended nozzle.[2]
