AAE 334, Fall 2011, Homework 2 SOLUTION Due Friday, August 26 at the beginning of class. Matlab review or introduction. Example 4.6 in the text is one example which we will take a close look at in a week. For now, we will prepare a plot to review or learn use of Matlab and to aid us when we study the example. Create an m-file to: 1. compute and plot the camber line shape given in Example 4.6 versus chordwise position in meters. Chord is 2 meters. I suggest that you use 401 points along the chord including leading edge and trailing edge. For example, define a vector of non-dimensional chordwise points: xnondim = 0:0.0025:1; Then, when you need, for example, 3 c x you would write: xnondim.^3 and note that the .^3 operator is very different from ^3 Note that with 401 points the break point in the camber equation, 2025 . 0 = c x , is the 82 nd point in the xnondim vector. 2. Compute and plot what we will see to be one important quantity along the chord, the “vortex sheet strength”: () () () ( + + = ) / 2 1 arccos( 2 sin ) / 2 1 arccos( sin ) / 2 1 arccos( sin / 1 2 2 2 1 0 c x A c x A c x c x A V x γ ) Example 4.6 solves for two important constants: A
