Rocket Engine shock diamonds - XCOR 5K18 "Lynx" engine

[EinhanderSn0m4n]

Your exhaust flow is a bit underexpanded; maybe a bigger nozzle can get a bit more thrust at sea level. Nice proof of concept, though :)

Correct. Proper expansion wasn't the point with this test.

That is an impressive shock diamond. How are you able to display it so clearly? infrared camera or something?

[XCORAerospace]

Just closing down the iris, gain and the shutter speed until it is very dark. You need a camera that can go full manual to do this.

Keep up the excellent work, everyone. It's great to see the 5K18 up and running. -Geo

minor correction on our title slate: The slate indicates a 6 second run, this run is actually eight seconds in length.
