← TechnologyWhich risk increases when an unmanned underwater vehicle (UUV) operating in cold arctic waters experiences rapid propeller acceleration?
A)Increased electrolytic corrosion of seals
B)Elevated dissolved oxygen concentration
C)Reduced acoustic communication bandwidth
D)Propeller blade cavitation and erosion✓
💡 Explanation
Cavitation risk increases because rapid propeller acceleration lowers local pressure below the water's vapor pressure, forming bubbles and then causing their implosion against surfaces upon collapse; therefore, erosion occurs, rather than seal corrosion from low temperature or water conditions affecting communication.
