1. 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, a cellular material disposed in the mixing plenum;
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.
