Abstract
A fuel injector 46 for a turbine engine includes an elongated, generally cylindrical metal housing 76 having a cylindrical surface 78 terminating in an end 84 having a frustoconical surface 86. A bore 88 having an axis 89 normal to the frustoconical surface 86 extends through the housing 76 to provide an air inlet 90 in the cylindrical surface 78 and a fuel and air outlet 94 in the frustoconical surface 86. The bore 88 is narrowed at the outlet to provide a constriction 110 thereat. A curved tube 96 of substantially lesser diameter than the bore 88 is located within the bore 88 to serve as a fuel injecting tube and has an open end 100 on and normal to the axis 89 and located in close adjacency to the constriction 110 without increasing the resistance to air flow through the constriction 110.
