A main body is provided for a gas turbine engine comprising an outer structure, a first internal partition and a second internal partition. The outer structure and the first internal partition may define an entrance leg of a cooling circuit for receiving a cooling fluid. The second internal partition may include a metering slot. The outer structure, the first internal partition and the second internal partition may define an intermediate leg of the cooling circuit. The intermediate leg may communicate with the entrance leg. The second internal partition and the outer structure may define an exit leg of the cooling circuit. The metering slot meters cooling fluid as it passes from the intermediate leg into the exit leg.
