NASA has successfully developed and tested the first full-scale rotating detonation rocket engine (RDRE).
The RDRE achieved its primary test objective by demonstrating that its hardware – made from novel additive manufacturing, or 3D printing, designs and processes – could operate for long durations while withstanding the extreme heat and pressure environments generated by detonations.
This advanced rocket engine design could significantly change how future propulsion systems are built.
