And since SpaceX was confident enough to put 9 turbo pumps in a stage, I don't see why they would ever feel the urgent need to reduce to only one turbo pump. It's just not going to happen, with good reason.
Realistically, though, if a multi-chamber rocket design is pursued - SpaceX would design a larger thrust chamber anyway.Unless you propose a 9 chamber design with the current Merlin 1D thrust chamber... Which would be pointless, since we know the 9 engines do work together.And since SpaceX was confident enough to put 9 turbo pumps in a stage, I don't see why they would ever feel the urgent need to reduce to only one turbo pump.

Let me say P&W understands pumps real well ...watch the video
Baldusi - give it up. They are not going to use AJ-500 or any russian engine.

This "sickness" of NIH has got to stop. There are lots of smart people in the world and only some of them are American. There are even some in (OMG) Russia.
When they need a larger engine, I think they'll make as large of a thrust chamber they can, and then just duplicate that engine 2, 3, 4 or more times to get the thrust they wanted.

He brought AC with him from Serbia.
If we have to split hairs on Tesla... Quote from: clongton on 10/30/2011 01:12 amHe brought AC with him from Serbia.Close, but not quite. He was a Serb by nationality, but he never actually lived in Serbia. Born in Croatia, after finishing high school he went around Europe (Austria, Hungary...) for a while before finally coming to the U.S. and becoming a citizen.
