When does embedded shock wave appear on the cone kept at an angle?(a) Angle of attack = half cone angle(b) Angle of attack > half cone angle(c) Angle of attack < half cone angle(d) Shock wave angle = 90 degreesI have been asked this question in semester exam.Question is from Cones at Angle of Attack in chapter Three-Dimensional Flow of Aerodynamics

Answer»

Correct answer is (b) Angle of ATTACK > half cone angle

The best explanation: Embedded shock waves appear over the leeward SURFACE of the cone when the cross – flow velocity increases thus becoming supersonic. These waves are prevalent only when the angle of attack is greater than the half – cone angle and are USUALLY weak in NATURE.
