NASA recently conducted a successful test ofa completely new type of rotary detonation rocket engine (RDRE) at Marshall Space Flight Center in Huntsville, Alabama. This RDRE test, which lasted 251 seconds by simulating the duration of a mission to Mars, generated more than 26 000 Newtons (about 3 tons) of thrust. The objective is to achieve 44 000 Newtons for an operational system capable of supporting various space missions.
RDRE: Innovative technology for optimized interplanetary travel
Technology RDRE promises to reduce fuel consumption by 25% while offering thrust equivalent to traditional engines. His secret? The use of small, controlled explosions inside a combustion tube.
By using the same fuel and oxidizer as conventional rocket engines, the RDRE aims for better energy efficiencyincreased thrust and a larger payload for future missions to Mars and beyond.
While the Japanese SLIM probe is currently in lunar orbit, NASA is not left out and is also making progress in technologies linked to space conquest.
Technical challenges for NASA
Although promising, the development of the RDRE presents stability and explosion control challenges. NASA, in collaboration with partners like GE Aerospaceactively seeks to overcome these technical difficulties.
Efforts are focused on improving the technology to achieve a fully reusable RDRE engine generating more than 40 tons of thrust. Enough to compete with or complement Space X’s Starship 2? Possible.
Towards faster and more efficient space travel
Thanks to this major breakthrough during the tests in Alabama, NASA is moving closer to the goal of develop extremely efficient propulsion systems for future deep space missions.
Its engineers work closely with industrial partners to optimize RDRE technology. The space agency is also studying other revolutionary concepts, such as nuclear propulsion, to reduce trips to Mars to just 45 days !
Understand the science behind innovation
Combustion by detonation of RDRE, faster and more efficient, is a complex supersonic chemical phenomenon requiring advanced mastery of fuel chemistry and fluid dynamics.
NASA is taking on this exciting technological challenge to make deep space exploration more accessible than ever. Its cutting-edge scientific expertise is put to the service of innovation to push the limits of the space adventure.
