Question

In a jet engine's combustion chamber, detonation refers to

• A. Subsonic burning of fuel-air mixture producing steady pressure
• B. Supersonic combustion producing a shock wave and sudden pressure rise
• C. Use of turbines to compress the fuel-air mixture before ignition
• D. Acceleration of exhaust gases through a convergent nozzle

Hint:

Combustion types: \[ \boxed{ \begin{aligned} \text{Deflagration} &\rightarrow \text{Subsonic flame propagation} \text{Detonation} &\rightarrow \text{Supersonic flame propagation with shock wave} \end{aligned} } \]

Answer 1

The Correct Option is B
