Title: What is the ORSC engine cycle?
Post by: TeenSpaceNerd on 07/26/2017 04:55 pm

I heard it is being used on the BE-4.  When I Google it, I get Organic Rankine Cycle (ORC).Does anyone have diagrams of an example ORSC engine?

Most Russian engines, including the RD-180 used on Atlas V, use ORSC.
