Beryllium-Metal Matrix Composite Compressor Blade Program.
Abstract
The objective of this program was to develop beryllium reinforced titanium matrix composite blading for gas turbine fans and compressors. Ten TF-41 LP3 composite compressor blade airfoil forgings were produced by isothermal forging of coextruded Be rod - Ti (6Al-4V) preforms. Monolithic Ti 6Al-4V root blocks were diffusion bonded to six of the composite airfoils by hot isostatic pressing. Two blades were completely machined on production type tooling to dimensionally acceptable configuration. Resonant bending and torsional frequencies of the composite blades were increased up to 32% over production Ti 6Al-4V monolithic blades with blade weight savings up to 20%. Ballistic impact behavior of coextruded Be rod - Ti (6Al-4V) composites with other titanium matrix composites was determined.
