ABSTRACT:
A method for distributing a flow of fuel over the gas flow area of a gas turbine engine includes the steps of dividing the gas flow area into a plurality of sector shaped sub-areas (48), (50), (52), (54) disposed within a surrounding, annular sub-area (46) which is in turn disposed adjacent the augmentor wall (12). During operation, the method according to the present invention distributes the fuel over one or more of the sub-areas (46-54) in response to the current rate of fuel flow. At the lowest and intermediate fuel flow rates, fuel is distributed only over one or more of the sector shaped sub-areas (48-54). Only at the very highest rates of augmentor fuel flow is fuel distributed finally in the outer annular sub-area (46).
