Hello to all.
I'm curious about this rocket concept after seeing tons of unbuilt projects (Truax, Percheron, OTRAG, Scorpius, Beal...) using this method.
From what I've understand with my limited knowledge
- pressure-fed are cheaper because they have no turbopump
- but this is more or less offset by heavier tankage
More details ? Debate is open...
