Question

Which of these methods is not a local inclination method for computing pressure distribution?

(a) Newtonian theory

(b) Tangent wedge theory

(c) Tangent cone theory

(d) Oblique shock method

The question was posed to me in an interview.

This question is from Time-Marching Technique topic in portion Time-Marching Technique of Aerodynamics

Answer 1

The correct answer is (d) Oblique shock method

To elaborate: There are three other local surface inclination inclinations, in addition to Newtonian theory. Methods that are widely used to estimate distributions of pressure over hypersonic bodies are the tangent wedge method, tangent cone method and shock – expansion method.
