Putting the prototype Rotating Detonation Rocket Engine (RDRE) through its paces at the NASA Marshall Space Flight Center in Alabama has set new records for the technology, achieving 25,810 newtons (5,800 pounds) of thrust for 251 seconds.
That beats the 17,800 newtons of thrust managed for nearly a minute that the rocket engine managed in 2022, with the results validated early in 2023.
Eventually, the aim is to build a fully reusable 44 kilonewton class RDRE to improve on traditional liquid rocket engines.
“The RDRE enables a huge leap in design efficiency,” says combustion devices engineer Thomas Teasley, who is leading the RDRE project at the Marshall Space Flight Center.
What makes the RDRE so revolutionary is that it makes use of a sustained detonation circling around a ring-shaped channel, fed by a mix of fuel and oxygen which is ignited by each passing explosion.
Tһe tecһnologу һаѕ Ьeen іn deʋeloрмent for уeаrѕ, аnd іn lаЬ-Ьаѕed teѕtіng ѕіnce 2020, Ьᴜt іt’ѕ onlу now tһаt ѕcіentіѕtѕ аre ѕһowіng tһаt іt’ѕ ѕtаЬle аnd маnаgeаЬle enoᴜgһ to Ьe ᴜѕed іn аctᴜаl rocketѕ to tаke ᴜѕ to ѕраce.
Crucially, the RDRE uses less propellant fuel than conventional rocket engines, and is simpler in terms of its machinery and mechanisms. That means going into space becomes cheaper, and traveling further distances becomes possible.
