COMBUSTOR WITH DISTRIBUTED AIR AND FUEL MIXING

A combustor (100; 200) includes a liner (102) defining a combustion chamber (105) and receiving a fuel and air mixing body (104; 204; 300). The mixing body (104...300) has a central fuel supply (118, 120; 223,, 225; 302), and radial distribution passages (128, 138, 142; 224, 230, 239; 304, 314, 318, 322, 330, 338) communicating fuel from the central fuel supply (118..302) radially outwardly relative to a central axis (C) of the central fuel supply (118...302) and to mixing passages (110, 113, 136, 140; 210, 212, 220, 236; 310; 320, 328). The radial distribution passages (128...338) have injection ports (130) in the mixing passages (110...328). The mixing passages (110...328) extend from a rear face (106; 206) of the mixing body (104 ...300) to an inner face (116; 214) facing into the combustion chamber (105). Air inlets (108) in the mixing body (104...300) communicate air into the mixing passages (110...328), and there is cellular material (114; 213, 221) in the mixing passages (110...328) at a location at which the fuel is injected into the mixing passages (110...328). A gas turbine engine (20) is also disclosed.
