ABSTRACT:
In a nozzle for atomizing fuel into a spray for combustion in gas turbine engines, wherein the atomization is effected by the use of high velocity and/or high density air, and wherein the supply of fuel to two separately metered points is such that at low flow rates the first fuel supply is spread into a thin sheet for atomization but at high flow rates the second fuel supply is spread into a thicker sheet which combines with the thin sheet produced from the first supply, thus resulting in a single spray of constant shape at all operating conditions.
