Compressor Blade Manufacture by Electrochemical Machining. Advanced Turbine Engine Gas Generator.

Abstract

Compressor blades for the ATEGG GE14 engine manufactured using electrochemical machining to form the airfoils. Elaborate dimensional inspections were performed on the as-machined surfaces. The blades were tested for frequency, nodal patterns, and fatigue strength and were compared to control blades made by conventional methods. (Author)
