Abstract: Combustor systems are provided that include rotating detonation combustors (RDCs) arranged in series. In some embodiments, a combustor system includes a volume that receives a core oxidizer-fuel mixture. The combustor system includes a first RDC having a first detonation chamber. The first detonation chamber receives a first pilot oxidizer-fuel mixture and is bounded by a first channel formed in a peripheral wall. The combustor system further includes at least one additional RDC having a second detonation chamber. The second detonation chamber receives a second pilot oxidizer-fuel mixture and is bounded by a second channel formed in the peripheral wall. The first pilot oxidizer-fuel mixture reacts in the first detonation chamber and the second pilot oxidizer-fuel mixture reacts in the second detonation chamber to generate rotating detonation combustion waves that are guided by the first channel and the second channel to support a reaction that consumes the core oxidizer-fuel mixture.

Abstract: A high-speed, air-breathing propulsion engine includes an inlet configured to compress incoming air, a fuel injector configured to supply a fuel for mixing with the compressed incoming air to form a fuel-air mixture, and a combustor configured to burn the fuel-air mixture. The combustor includes a rotation detonation combustor system and a bluff body system that cooperate to generate thrust.
