AAE 334 Fall 2011, Homework 24 SOLUTIONS Due Wednesday, November 9 at the beginning of class. 1. Using an oblique shock chart, answer these questions: a. What is the turning angle in degrees for an upstream Mach number of 2 and a wave angle of 40 degrees? b. What is the upstream Mach number for an oblique shock with turning angle of 15 degrees and wave angle of 53 degrees? c. What is the wave angle in degrees for the weak shock solution for an oblique shock at Mach 2.25 and turning angle of 10 degrees? d. What is the wave angle in degrees for the strong shock solution for an oblique shock at Mach 2.25 and turning angle of 10 degrees? 2. Using the Matlab functions such as OS_tw, OS_mw, OS_mt, or OS_mt_str , and the normal shock functions as needed, compute and plot the static pressure on the bottom of a flat plate airfoil in a Mach 2 flow versus angle of attack for o 10 0 . Plot in units of 1 p . Hand in hardcopies of your Matlab code and plot.
