← ScienceWhich increased risk follows when volatile liquid rocket propellant experiences rapid depressurization?
A)Detonation via rapid phase explosion✓
B)Sublimation dominating convective heat transfer
C)Oxidizer condensation halting combustion
D)Turbopump housing embrittlement accelerating fatigue
💡 Explanation
Rapid depressurization can lead to flash boiling and explosive vaporisation— a rapid phase explosion; hence, detonation. The extremely fast vaporisation exceeds the propellant's ability to manage the phase transition via controlled bubbling, because the sudden volume increase generates intense pressure waves, rather than regulated expansion.
