1. A combustor system comprising:
a first wall defining at least in part a core that receives a core oxidizer-fuel mixture, the core including a first detonation chamber and at least one additional detonation chamber, the first wall including a first outer channel that extends circumferentially about the first detonation chamber and at least one additional outer channel that extends circumferentially about the at least one additional detonation chamber, wherein the first wall is common outer wall that directly borders the first detonation chamber and the at least one additional detonation chamber; and
at least one outer pilot oxidizer-fuel supply system that supplies a pilot oxidizer-fuel mixture to the first outer channel and the at least one additional outer channel;
wherein the pilot oxidizer-fuel mixture is configured to ignite to generate rotating detonation waves that are guided by the first outer channel and the at least one additional outer channel to support a reaction that consumes the core oxidizer-fuel mixture.
