A hot fire test of a 3D printed nozzle is shown with an orange fire being expelled at Marshall Space Flight Center in Huntsville, Alabama.

RAMFIRE Nozzle Hot Fire MSFC

The RAMFIRE nozzle performs a hot fire test at Marshall’s East test area stand 115. The nozzle, made of the novel aluminum alloy 6061-RAM2, experiences huge temperature gradients. As hot gasses approach 6000 degrees Fahrenheit and undergo combustion, icicles are forming on the outside of the engine nozzle. (Click here to download image)
