Question

In the subcritical operation mode of a supersonic inlet, shock strands

• A. at some distance away from the inlet
• B. at the lip of inlet
• C. inside the inlet
• D. at the entry of combustion chamber

Hint:

Correct positioning of shock waves in supersonic inlets is crucial for maintaining engine efficiency and avoiding performance penalties.

Answer 1

The Correct Option is B

Step 1: Define Subcritical Operation.
In subcritical operation of a supersonic inlet, the shock wave is positioned to manage air deceleration effectively without causing airflow separation or backflow.
Step 2: Location of Shock Wave.
In subcritical mode, the shock wave typically stands at the lip of the inlet, optimizing the compression without generating excessive backpressure or spillage.
