Abstract: A combustor includes a liner defining a combustion chamber. An air and fuel mixing body is received within the liner and upstream of the combustion chamber. The mixing body has a center axis and includes a bluff-body. A plurality of fuel injection ports on the bluff-body communicate with a central fuel supply such that fuel passes from the fuel supply passage and into a mixing chamber with a component in an axially downstream direction and a radially outward direction relative to said central axis. A plurality of inner air swirlers provide air into the mixing chamber with a component in an axially downstream direction, a radially outward direction, and with a circumferential component due to swirler structure. The fuel injection ports are downstream of an outlet of the inner air swirlers.
