The problem of maximizing the thrust in supersonic nozzles of given length has been treated previously by Guderley and Rao. Significant differences of the nozzle shapes may be encountered if the oncoming flow possesses a swirl around the axis of symmetry. The present paper extends the existing theory to this case. The final procedure turns out to be more complex, but the basic considerations carry over to the present case. Some space has been devoted to a discussion of a short cut by which Rao succeeded in by-passing the characteristic conditions. The report contains the basic theory only. Author
