Which outcome results when thermal energy escapes via conduction from a hybrid rocket engine?

A)Decreased combustion efficiency and thrust
B)Increased nozzle erosion from overheating
C)Fuel-oxidizer mixture ratio stabilization
D)Ablative cooling system improvement

💡 Explanation

Thrust decreases because heat loss through conduction reduces flame temperature, limiting complete combustion via the Arrhenius equation. This reduces expansion work, therefore, decreasing combustion efficiency and thrust, rather than eroding the nozzle.
