ABSTRACT:
In a gas turbine engine compressor power unit fuel is supplied at an essentially constant pressure to a fuel nozzle for injection into the combustion liner of the power unit's combustor. Nozzle fuel flow is modulated solely by bleeding off combustor supply air to vary the internal liner pressure, thereby altering the fuel pressure drop across the nozzle.
