A method for generating combustion products within a gas turbine engine includes directing an internal air/fuel mixture towards a stagnation point in close proximity to an inner surface of a porous wall defining a combustion chamber. The internal air/fuel mixture is ignited to generate combustion products including a pilot flame. A quantity of air is externally mixed with a quantity of fuel to produce an external air/fuel mixture. The external air/fuel mixture is directed through the porous wall and into the combustion chamber such that the external air/fuel mixture is ignited by the pilot flame. A direction of flow of the combustion products is reversed at the stagnation point.
