CTOnews.com, January 30 (Xinhua)-- as the National Aeronautics and Space Administration (NASA) prepares for the return of the Artemis mission to the moon, its researchers have successfully developed and tested a new supersonic rocket engine, the full-size rotary detonation engine rotary detonation rocket engine (RDRE).

The ▲ rotary detonation rocket engine conducts RDRE thermal ignition tests at the Marshall Space Flight Center. Tu Yuan NASANASA said that unlike traditional rocket engines, RDRE uses a supersonic combustion phenomenon known as detonation to generate thrust. This design can generate more power and use less fuel than today's propulsion systems, and has the potential to power human landers and interplanetary vehicles to reach deep space destinations such as the moon and Mars.

Engineers at the NASA Marshall Space Flight Center in Huntsville, Alabama, and partner in Space in West Lafayette, Indiana, conducted engine ignition tests, and the RDRE was ignited more than a dozen times for a total of nearly 10 minutes.

RDRE achieves its main test objectives by proving that its hardware can run for a long time and withstand extreme heat and pressure caused by detonation. At full power operation, the RDRE generates more than 4000 pounds (1814 kg) of thrust in nearly a minute at an average chamber pressure of 622 pounds per square inch, the highest rated thrust of the design on record.

CTOnews.com learned that NASA said the successful test brought the technology closer to future aircraft, allowing NASA and commercial space agencies to transfer more payload and mass to deep space destinations. NASA engineers are following up on the development of a fully reusable 10000 lb (4536 kg) thrust-stage RDRE to determine performance advantages over conventional liquid rocket engines.
