Abstract
A combustor includes a liner and an air fuel mixing body in a wall of the liner. A fuel supply passage provides fuel into the mixing body. The fuel then is injected through radial distribution passages into a mixing plenum. The mixing plenum receives a cellular material. Air supply passages deliver air into the mixing plenum. Downstream extending passages lead from the mixing plenum to an inner face of the mixing body for delivery of mixed fuel and air into a combustion chamber.

A combustor comprising:
- a liner and an air fuel mixing body in a wall of said liner, a fuel supply passage to provide fuel into said mixing body, the fuel then being injected through radial distribution passages into a mixing plenum, the mixing plenum receives a cellular material;
- air supply passages for delivering air into said mixing plenum;
- downstream extending passages leading from said mixing plenum to an inner face of said mixing body for delivery of mixed fuel and air into a combustion chamber;
- and
- said fuel supply passage being a central fuel supply passage defining a center axis of said mixing body, the radial distribution passages extending in a direction having at least a component perpendicular to said center axis, and the radial distribution passages extending into the mixing plenum before the fuel begins mixing with air from the air supply passages.
