← ScienceWhich outcome occurs when the hypersonic engine's nozzle ablates?
A)Reduced thrust and wasted fuel✓
B)Increased vehicle aerodynamic efficiency
C)Flameout due to richer mixture
D)Lower engine thermal management needs
💡 Explanation
Ablation widens the nozzle, reducing pressure and thrust, due to the mechanism of **isentropic expansion**. This also means that more fuel will be wasted because less work is extracted given a fixed volume of fuel injected; therefore, thrust reduces rather than increases efficiency.
