I just saw an article over at parabolicarc about AJR's first 3d-printed
thrust chamber firing. I’m trying to decide whether, from what I’ve read,
they’re substituting copper for stainless in a few spots.
I think design changes are probably unlikely this early, but at the very
least the new manufacturing process opens up the way for different
materials and more elaborate cooling passages that wouldn’t be possible
using the old tube benders. Is anyone on this list privy to what sort of
plans AJR has for higher chamber pressures or other improvements to the
RL-10? What’s the schedule for doing complete engine certification?
