Which risk increases when turbine blades in a jet engine experience significant surface roughness?

💡 Explanation

Surface roughness increases local stress concentrations; this accelerates crack initiation because fatigue cracking grows through crack tip plastic deformation. This leads to faster blade failure, therefore increasing fatigue cracking, rather than compressor stall issues under reduced performance conditions.
