A gas turbine engine airfoil is manufactured by forming an internal retention seat in two complementary airfoil parts. An insert is fabricated for retention in the seat. The two parts are assembled with the insert disposed in the seat therebetween. The parts are then bonded together to trap the insert therein to collectively define the airfoil. The insert and seat may be precisely fabricated for improving the efficiency of the airfoil.

[What is claimed is:] [1.]forming an internal retention seat entirely inside two complementary airfoil parts;fabricating an insert configured for retention in said seat;assembling together said two parts, with said insert therebetween in said seat; andbonding together said two parts to trap said insert therein, and collectively define said airfoil. [16.]a hollow retention hub configured for being trapped in said retention seat between said parts; anda perforate tube extending from said hub for distributing said fluid in impingement inside said airfoil parts.said two airfoil parts collectively define a hollow airfoil having a radial passage for channeling said cooling fluid, and include a retention seat for trapping said baffle hub; and said baffle hub is larger in diameter than said baffle tube to trap said hub in said seat, and space said tube from said airfoil parts for impingement cooling thereof.said airfoil includes a plurality of said seats radially spaced apart from each other; andsaid baffle further comprises a plurality of said baffle hubs for being disposed in respective ones of said seats in radial alignment.
