Which issue dominates when airborne volcanic tephra encounters jet engine turbines?

A)Acceleration of high-cycle fatigue cracking
B)Electrostatic interference with control circuits
C)Dissolution of turbine blade alloys
D)Deposition resulting from homogeneous nucleation

💡 Explanation

High-cycle fatigue accelerates because abrasive particles impact rapidly causing micro-cracks as a result of abrasive wear; therefore, blades fail prematurely, rather than exhibiting issues from conductivity or general chemical corrosion.
