← ScienceWhich mechanism initiates acoustic fatigue when a turboprop engine nacelle experiences rapid airspeed fluctuations?
A)Boundary layer transition✓
B)Material phase transformation
C)Friction induced expansion
D)Resonant frequency excitation
💡 Explanation
Boundary layer transition becomes turbulent due to rapid pressure changes; this generates unsteady pressure loads on the nacelle causing acoustic fatigue because the turbulent fluctuations induce random vibrations rather than uniform stress.
