An expander cycle engine, LN2 cooling the engines? I've never heard of it being done _that_ way before. Probably as simple a way to run a turbopump as could be done.

Probably as simple a way to run a turbopump as could be done.It looks like the "Pneumopump aggregate" isn't a turbopump. It seems like some kind of pistonless pump system from the NK thread, but google translate isn't really enough for me to tell exactly how it's supposed to work.Also, the LV in the diagram posted up thread is only one of several designs on the spacelin site and NK thread.I think http://www.spacelin.ru/#!taymyr/c1wuk is pressure fed H2O2/Kero, and http://www.spacelin.ru/#!aldan/c99b is LOX/Kero using a full Soyuz core engine.My impression from the NK thread is that the H202 design is the one under development, but again, caveat google
My strong suspicion is that the engines shown in the cartoons are not actually going to be based on the RD-108 verniers, but rather would be a new design, with the reference to RD-108 being shown as an existence proof.

The Russian moon base won't.

There are actually frequent updates on Linspace.ru site now.
I read the guy who developed and sold Minecraft ($2.5B) is bored. Maybe he could start or invest in a newspace company.
