This patent describes a gas turbine engine. It comprises a rotary compressor; a turbine wheel coupled to the compressor for driven movement thereof; an annular nozzle proximate the turbine wheel for directing gases of combustion thereat; an annular combustor defining an annular combustion space disposed about the turbine wheel and in fluid communication with both the compressor and the nozzle, the combustor including a cylindrical wall having at least one igniter mounted therein, the combustor receiving fuel from a source and air from the compressor and combusting fuel and air in the combustion space to generate the gases of combustion; and at least one impingement fuel injector for injecting fuel from the source into the combustor, the impingement fuel injector comprising at least one generally radially opening discharge orifice and an impingement surface within the combustor in the path of fuel discharged from the orifice and at an angle thereto so as to produce a flat, diverging spray of fuel in a direction generally circumferentially about and tangential to the combustion space, the igniter being positioned in the cylindrical wall in the path of the flat, diverging spray of fuel from the impingement fuel injector.
