This patent describes a gas turbine engine. It comprises: a rotary compressor; a turbine wheel coupled to the compressor to drive the same; an annular nozzle proximate the turbine wheel for directing gases of combustion at the turbine wheel; 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 receiving fuel from a source and air from the compressor and combusting the same to generate the gases of combustion; and fuel injectors at circumferentially spaced locations about the combustor, each the fuel injector having means for defining an elongated passage of such size and length that flow of fuel through the passage will be laminar, the elongated passages being radially inwardly opening, each the fuel injector further including a fuel impingement surface within the combustor in the path of fuel discharged from the elongated passages and at an angle thereto so the fuel will be sprayed generally tangential to the combustion space.
