To quickly assess the difficulty of the text, read a short excerpt:
6 is not quite certain. Each of the streamlines shown in the figijre may serve as a nozzle contour. For the purpose of comparison these different streamlines were so magnified that they correspond to the same throat diameter and then superim- posed. The result is shown in Table III, The coordinates of points on these contours corresponding to throat, transition, and exit are given in Table IV; R being the radius of curvature at the throat. The contour correspond- ing to 77 =, 1 is omitted becau...se it would be too long; even the contour t^ = . 2 is rather long. It appears reasonable to employ the line 7^ = . 5 for design. (The line 77 =, 6 is not much shorter and its location is uncertain. ) The contoior 97 = . 5 yields a length of 2, 5 throat diameters between throat and exit, a length which appears rather acceptable. As to the details of the calculation, the following may be mentioned. The basic flow F^ was chosen as one whose streamlines are essentially hyperbolas; more exactly h =/l+|^ in the terminology of Part I of the previous report.
