I'm trying to get a hold of various technical specifications for the RD-171MV engine
A modification of RD-171M being developed for the Irtysh rocket. Unlike RD-171M it's completely made from Russian components and features a new control system. First test sample was manufactured in early 2019.
I'm looking for the "usual suspects", details like:
- Thrust/weight ratio
- Expansion Ratio
- Chamber pressure
- O:F ratio
It would be great if I can find old as well as new data for comparison.
