ABSTRACT:
The problems of carbon build-up, poor fuel atomization, and fuel leakage in fuel injectors for turbine engines may be avoided if the fuel injector is fabricated by a method including the steps of: (a) providing a barrel (26) having an outlet end (44) adapted to be disposed in a turbine engine combustor (10), an inlet (46) adapted to be in fluid communication with the compressor of a turbine engine, an internal passage (40) extending between the inlet (46) and the outlet end (44) and a constriction (48) in the internal passage (40) between the inlet (46) and the outlet end (44) to define at least a partial venturi, (b) disposing a fuel tube (52) having a fuel injection end (54) within the internal passage (44), and (c) locating the fuel injector end (54) with respect to the constriction (48) at a position such that maximum fuel suction pressure is attained with a minimum reduction in air mass flow rate during operation of the injector.
