COLUMBUS, OH--The Navy Joining Center (NJC) is studying the use, of translational friction welding to produce titanium bladed-disk (blisk) components for turbine engines.
This project is a cooperative effort with Naval Air Systems Command, the Edison Welding Institute and an industry partner. The blisks will enhance the performance of Navy aircraft.
In conventional aircraft turbine engines, the airfoil and blades are mechanically attached to the rotor disk. The blades are attached individually to the disk by a precisionmachined dovetail slot arrangement.
In contrast, advanced engines for military jets use a one-piece blisk. The disk and blades ...
