An air dispensing arrangement within a gas turbine engine in which the energy of the pressurized air exiting the compressor is nonuniform. The higher energy pressurized air is dispensed by at least one conduit to the combustor and to other components, the higher energy air providing an improved cooling capability over the lower energy air. Provision is also made to employ the lower energy air for uses such as the dilution of the combustor gases.

In a gas turbine engine combustor having a compressor which provides an airstream to a duct which diffuses the airstream, the improvement comprising: (a) means for tapping first and second airstreams from the diffusing airstream and for carrying the airstreams in respective primary and secondary conduits, the average energy level of the air in the primary conduit being higher than the average energy level of the air in the secondary conduit; (b) means for directing air from the secondary conduit into the combustor for diluting combustion gases; (c) means for directing air from the primary conduit into a hollow stator located near the outlet of the combustor for cooling the hollow stator.
