Airblast injector for a gas turbine engine

An airblast injector assembly, comprising:

• a fuel swirler generating a fuel spray cone having a spray cone angle, the fuel swirler having an injector tip diameter, where said fuel swirler includes an inner tapered surface having a shape of a frustum of a cone with a cone angle equal to the spray cone angle;
• a swirler cup having an inner tapered surface having a shape of a frustum of a cone having a cone angle equal to the spray cone angle and positioned to accept the fuel spray cone from the fuel swirler adjacent to and at constant distance from the inner tapered surface of the swirler cup, where said swirler cup includes a plurality of air exiting orifices which accept a pressurized airstream and are positioned annularly around said inner surface at a swirler location diameter, the plurality of air exiting orifices directing said airstream towards the fuel spray cone, the plurality of air exiting orifices having a down angle and a back angle relative to a line that is perpendicular to said fuel spray cone;
• an outlet defining a fuel exiting orifice;
• and
• a combustor dome, the outlet defining the fuel exiting orifice connecting the fuel swirler to the combustor dome,
• wherein the swirler cup is positioned upstream from the combustor dome.
