A gas turbine engine (10) includes a compressor (18) powered by a turbine (24). The turbine (24) includes a nozzle (34) having vanes (42) extending between outer and inner bands (44,46). Each vane (42) includes an internal cooling plenum (48) and a bypass tube (50) extending through the bands (44,46). First and second manifolds (52,54) surround the outer band (44) and are disposed in flow communication with the plenums (48) and bypass tubes (50), respectively. A bleed circuit (56) joins the compressor (18) to the manifolds for providing pressurized air thereto. A control valve (58) modulates airflow to the first manifold (52) and in turn through the cooling plenums (48) of the vanes.
