Impact Damage on Titanium Leadng Edges from Small Soft Body Objects

Abstract

Impact damage on titanium leading edge configurations was investigated by performing leading edge soft-body impacts on flat-edge and tapered-edge specimens. The objectives were to determine the laboratory specimen size, boundary condition, and test methods necessary to adequately simulate the leading edge local damage of actual blades from soft-body impacts (such as birds). The effects of leading edge geometry, specimen mounting, impact velocity, impactor type, impactor size, and impact angle were investigated. The damage modes excited in ti-tanium were identified. Damage measurement techniques were devised and the damage quantified. Comparisons of the damage were drawn regarding the effects of specimen size and mounting.
