Abstract
A gas turbine engine fuel injection apparatus comprises a fuel spray atomizer which directs a fuel spray onto the radially inner surface of an annular flow deflector. The fuel flows in a film over the flow deflector surface towards an annular lip at the downstream end of the deflector. Swirling air flows are directed over the radially inner and outer surfaces of the flow deflector so as to atomize the fuel as it leaves the annular lip. The fuel is evaporated in the swirling airflows and thoroughtly mixed with the airflows in a mixing duct before being discharged into a combustion chamber. The thorough mixing of the evaporated fuel and the airflows prior to combustion results in the production of reduced quantities of the oxide of nitrogen.
