"Radius deviations are for radii less

scale. In the regions of and 180 

 degress, it is observed that the wall is 

 thinner than nominal and that the 

 curvature is flatter than that of the 

 membrane circle . The center of the 

 membrane circle for the outer waU is 

 offset from the center of the inner wall 

 by about 0.02 inches. 



Another cross-sectional view at 

 elevation 4 = 0.4 is shown in Figure 

 B-6. The data are a compilation from 

 several specimens of t/D = 0.037.
