Diffusion Bonded Boron/Aluminum Spar-Shell Fan Blade.

Abstract

The Diffusion Bonded Boron/Aluminum Spar-Shell Fan Blade Program consisted of a design and a process development tasks intended to demonstrate composite blade application in large high-bypass ratio turbofan engines. The design task included selection of a representative airfoil model; a preliminary design effort, which included parametric studies of component materials and geometries, leading to the selection of two candidate designs, subject to NASA Project Manager approval, for detail designing; and a detail design effort on two designs which would lead to pertinent structural property definition and a detailed blade specification drawing. The process development task consisted of a process optimization effort leading to specification with the NASA Project Manager's approval of process parameters to be used in the follow-on effort of fabricating two simulated airfoils, nondestructive evaluation (NDE) measurements including primary frequency testing of sane and delivery of subject airfoil pressings to NASA-Lewis.
