When the right – circular cone is kept at an angle of attack to the free – stream, what is it considered to be?(a) One – dimensional(b) Two – dimensional(c) Three – dimensional(d) Four – dimensionalThis question was addressed to me during an online interview.Origin of the question is Cones at Angle of Attack in section Three-Dimensional Flow of Aerodynamics

Answer»

Right answer is (c) Three – dimensional

Explanation: When the right – circular cone is KEPT at a ZERO angle of attack to the free – stream, it is KNOWN to be axisymmetric and is known to be a two – dimensional flow. But, when it is kept at an angle of attack, the flow no longer remains two – dimensional. The shock wave more or LESS remains the same but the flow becomes three – dimensional.
