Aerospace Engineering > GATE 2023 > Shock Waves
A supersonic aircraft has an air intake ramp that can be rotated about the leading edge O such that the shock from the leading edge meets the cowl lip as shown in the figure. Select all the correct statement(s) as per oblique shock theory when the flight Mach number M is increased.
A
It is always possible to find a ramp setting θRAMP such that the shock still meets the cowl lip (βSHOCK remains the same).
B
If θRAMP is held fixed, the shock angle βSHOCK will increase.
C
If M exceeds a critical value, it would NOT be possible to find a ramp setting θRAMP such that the shock still meets the cowl lip (βSHOCK remains the same).
D
Shock angle βSHOCK < sin-1(1/M)

Correct : a
