Trapped insert turbine airfoil

摘要

A gas turbine engine airfoil (10) is manufactured by forming an internal retention seat in two complementary airfoil parts (26, 28). An insert is fabricated for retention in the seat. The two parts (26, 28) 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 (10), The insert and seat may be precisely fabricated for improving the efficiency of the airfoil.
