← ScienceWhich risk increases drastically when exceeding an engine's derated temperature?
A)Thermal runaway leading to catastrophic destruction✓
B)Decreased overall engine operational noise
C)Increase in thermal efficiency rating
D)Enhanced fuel or chemical combustion byproducts
💡 Explanation
Thermal runaway from elevated temperature accelerates oxidation, because exothermic oxidation reactions increase system temperatures further via positive feedback. Therefore thermal runaway accelerates material degradation rather than a state of equilibrium because cooling strategies and design limits prevent unbounded increases under nominal constraints and steady state behavior.
