NASA’s 3D-Printed Rotating Detonation Rocket Engine

NASA’s Marshall Space Flight Center in Huntsville, Alabama, has achieved a significant milestone by successfully testing a novel 3D-printed Rotating Detonation Rocket Engine (RDRE). The test, lasting 251 seconds and producing more than 5,800 pounds of thrust, emulates typical requirements for a lander touchdown or a deep-space burn that could set a spacecraft on course from the Moon to Mars.

Key Achievements and Collaborations

1. Sustained Burn: The 251-second burn marks a significant achievement, showcasing the RDRE’s capability for extended propulsion needs.
2. 3D-Printed Innovation: The RDRE is 3D-printed, demonstrating NASA’s advancements in additive manufacturing for cutting-edge propulsion systems.
3. Partnerships: The test is a result of collaboration between NASA’s Marshall Space Flight Center, In Space LLC, and Purdue University. The partnerships aim to push the boundaries of propulsion technology.

Scalability and Diverse Applications

The primary goal of the latest test is to understand how to scale the combustor to different thrust classes, allowing the RDRE to support various engine systems. This scalability opens up possibilities for diverse applications, including landers, upper stage engines, and supersonic retropropulsion for decelerating payloads or humans landing on Mars.

Leap in Design Efficiency

RDRE has the ability to enable a significant leap in design efficiency. The technology represents a step closer to creating lightweight propulsion systems that can send more mass and payload further into deep space, aligning with NASA’s Moon to Mars vision.

Collaborative Efforts

NASA’s Glenn Research Center and researchers at Venus Aerospace are working with NASA Marshall to identify ways to scale the RDRE technology for higher performance. The RDRE is managed and funded by the Game Changing Development Program within NASA’s Space Technology Mission Directorate. The successful test marks a key advancement in NASA’s pursuit of innovative propulsion systems for future deep-space missions.
