ABSTRACT:
An annular combustor for a gas turbine engine having a rotatable fuel slinger has a first plurality of effusion cooling holes for directing air flow radially inwardly toward said fuel slinger and circumferentially in the direction of rotation of the fuel slinger and a second plurality of effusion cooling holes on the opposite side of the fuel slinger for directing air radially inwardly and circumferentially in the direction of rotation of the fuel slinger, thereby to produce a pair of annular axially spaced helical air flow patterns having a confluence in the direction of fuel flow radially outwardly from the fuel slinger.
