High speed video rocket mach diamond shock diamonds

Closeup of rocket fire in high speed, with a bit of a startup transient. The pulsing at the end is the purge gas pushing the extra propellant in the lines out.

The rocket is hinged and is commanded to move slightly.

The mach diamonds are a bit ugly because there was some minor throat damage early in the engine's life.

300 frames per second' played back at 1/10th speed.

why using liquid oxygen



[bbrockert]

@yavan211 It's the best oxidizer.

I want to ask

What is it, like the crumbs that fall / peeling away from the pipe near the nozzle

crumbs are falling like dust and white smoke

thank

[bbrockert]

@deeblueseaful It's frost falling off a liquid oxygen line.

@bbrockert

condensation of water vapors and air its self.

[bbrockert]

@0xanier0 No, just water. It's pressurized LOX, so it's not cold enough to condense oxygen or nitrogen out of the air.

The regular universe is also pretty spectacular.

[bluestrayer]

actually shock diamonds (also called mach disks) are caused by the exhaust pressure being different from the ambient atmospheric pressure

@bbrockert

Fluorine the best

@jeremiah1st

No, in person. It zipped past me at over 500mph, but i saw the diamonds anyway.
