Coolable rotor blade assembly for an axial flow rotary machine

摘要

A coolable rotor blade assembly 10 of the type adapted for use in an axial flow gas turbine engine is disclosed. The assembly includes a rotor blade 12 and an impingement tube 14. A fiber metal seal 56 is disposed between the base of the rotor blade and the impingement tube. The seal contacts a seat 52 on the rotor blade and a face 54 on the impingement tube. The fiber metal seal has sufficient durability, flexibility, compressibility and density to enable sealing between the rotor blade and the impingement tube in a high temperature environment.
