Abstract
A fuel injector for a gas turbine engine comprises a hollow body having an upstream air inlet and downstream primary and secondary air outlet passages. The primary air outlets are disposed to direct primary air substantially parallel to the axis of the hollow body. The secondary air outlet passages are disposed radially inwardly of the respective primary air outlets and arranged to discharge secondary air outwardly so as to subject the primary air to shear. Fuel passages are disposed so as to discharge fuel through the primary air outlets in the same direction as the primary air. The shearing action promotes efficient atomization of fuel in the required distribution pattern without using a swirling action.
