Hi all,
I just wanted to ask from the wealth of experience here what materials
people prefer to use in an liquid propellant injector.
The engine I'm working on now runs Jet-A and LOX at 350 psi and r = 2.3
(when operating at its limit). For reasons relating to cost I've so far
been looking at 6061-T6 aluminum, but I'm now wondering whether that's the
right choice.
Is there a grade of copper that is preferable for something like this? Can
aluminum get the job done?
Thanks,
Jon
