Question 3 (10 Marks) a) A missile was tested in a wind-tunnel at supersonic Mach numbers. Now we want to simulate the trajectory of the missile. Explain as a design Engineer how to use the experimental results. Can you use the experimental results as it is? or not. Explain in detail.

b) Explain the reasons for a change in the nose shape of a missile nose from a sharp nose to a blunt nose. Using isentropic relations, compute the temperature and comment on the results at Mach M = 3, 5, 10, and 20.
