← ScienceWhich outcome arises when a pulse jet engine's reed valve fails to seal completely during operation?
A)Increased fuel consumption from backflow✓
B)Reduced thrust due to incomplete combustion
C)Engine overheating due to lean mixture
D)Vibration increase inducing structural failure
💡 Explanation
When the reed valve doesn't seal, intake backflow happens during combustion phase because reactants escape from the chamber, preventing complete combustion and increasing fuel consumption. Fuel consumption rises when that occurs, rather than incomplete combustion itself because the fuel-air mixture changes, producing an over-rich condition; alternatives need failures elsewhere.
