Figure 8 - Velocity Distribution About an Elongated Body of Revolution 



1.0 



The potential was determined at 0.2-in. intervals over the flat section of the body and 

 at finer intervals near the nose where the curvature is greater. The potential Y was plotted 

 as a function of x since -4-^ was known from Landweber's analysis. The x component of the 

 potential gradient was found from the faired curve through the experimental poir.ts as de- 

 scribed in Appendix A. The tangential velocities were obtained from Equation [17]. The ex- 

 perimental values of the velocity and pressure distributions are tabulated in Table 2 and are 

 plotted in Figures 8 and 9. The values computed by Landweber's theoretical method are
