Reply to NASA Validates Revolutionary Propulsion Design for Deep Space Missions by Gari_305
From the article
>As NASA takes its first steps toward establishing a long-term presence on the Moon’s surface, a team of propulsion development engineers at NASA have developed and tested NASA’s first full-scale rotating detonation rocket engine, or RDRE, an advanced rocket engine design that could significantly change how future propulsion systems are built.
Also from the article
>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. While operating at full throttle, the RDRE produced over 4,000 pounds of thrust for nearly a minute at an average chamber pressure of 622 pounds per square inch, the highest pressure rating for this design on record.
