What is the ORSC engine cycle?
« 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?

There is a Q&A on this topic here:

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