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
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]
