Abstract (en)
An improved burner system for a gas turbine engine has a central duct (23) for a fuel and air mixture and surrounded by a ring duct for an outer gas flow of fuel and air. The end of the inner duct is fitted with a cowl (35) with a selected pattern of apertures (37) which ensure a damping effect for pressure pulses in the two gas feeds. The cross flow of gasses through the cowl also ensure a thicker shear zone between the two gas flows resulting in an improved burn.
