200 REPORT NATIONAL ADVISORY COMMITTEE FOR AERONAUTICS A very simple geometrical picture of the parameters The constant = f 'P&V ls readily shown to be e and i p, exists for the cases discussed. In Figure 0 23 the value of e or <p — 6 at the point P is simply invariant to the choice of origin 0, as… … Figure 24 shows the Joukowsky airfoil defined by OMP, where OP = ae\ MP = R = ae+° , angle p = 0.10 and 5 = 45°, and Figure 25 shows the \p{0), OP M= e ; also, MOX=8, MOP = 6- -8, 0MP = t- \p(<p), e(0), and e(<p) curves for this airfoil. (<p — 8). Then by the law of cosines, we have = 1+2 p cos (<p…
