Astrobotic Breaks Records for Hot Firing Rotating Detonation Rocket Engine (RDRE)
An Astrobotic representative discusses the Chakram rotating detonation engine, its test results, and potential uses in the company’s vehicles and lunar landers.

A large-scale engine milestone
Astrobotic tested a 4,000-pound rotating detonation engine, which the representative describes as among the biggest and most powerful examples demonstrated to date. Across the tests, it generated more than 4,000 pounds of thrust and maintained combustion during each long run.

Why the scale matters
Many previous rotating detonation engine demonstrations operated at a few hundred pounds of force. Astrobotic scaled the design up to support future systems that need higher performance. The team says early results look strong, though further analysis remains.

How Chakram works
The Chakram model shown matches the tested hardware, which used two thrust chambers and an aerospike nozzle rather than a large bell-shaped nozzle. Three supersonic detonation waves circle the engine, enabling rapid combustion.

Potential uses across Astrobotic
Astrobotic is exploring how to incorporate Chakram into existing product lines. A future Zondor reusable rocket variant could use the engine to carry more payload or reach greater altitude or speed. The company is also considering applications in its lunar lander architecture.

A lean team delivers the test
The representative credits a small team spread across several offices and working with a modest budget. They say the first attempt achieved the intended milestone, and the initial engine performance met expectations.
