Question

What is the use of Newtonian theory?

(a) Get pressure distribution over hypersonic body

(b) Get pressure distribution over supersonic body

(c) Get coefficient of drag over hypersonic body

(d) Get coefficient of lift over hypersonic body

I got this question during an online interview.

Enquiry is from Newtonian Theory in chapter Numerical Techniques for Nonlinear Supersonic Flow, Elements of Hypersonic Flow, Couette and Poiseuille Flow of Aerodynamics

Answer 1

The correct answer is (a) Get pressure distribution over hypersonic body

Explanation: We use Newtonian theory for the purposes of Hypersonic flow problems. It gives us the pressure distribution over the surface of the hypersonic body for both straight and curved surfaces. Newtonian theory gives an approximate estimate rather than an exact result.
