A cooling air transferring apparatus is provided particularly for transferring cooling air from hollow convergent flaps and seals to hollow divergent flaps and seals respectively in aircraft gas turbine engine variable nozzles. The preferred embodiment includes two semi-circular tubes, the first partially received within the second and both having a common center and radius of curvature so as to slide about the pivot point of the variable nozzle's pivotable convergent and divergent flaps and seals. The preferred embodiment further includes an entrainment opening on the second tube through which part of the first tube is received. The entrainment opening induces cooling air from the nozzle bay into the cooling air transfer tube to help cool the divergent flaps and seals.
