A brief review is given of the linear theory for supersonic axisymmetric jets together with a discussion of various anomalies which arise. The method of characteristics is applied to the linearised equations of motion. In this way an analytical expression is found for the velocity change across the initial expansion fan. A special procedure is developed for carrying out an asymptotic analysis of the full equations of motion in the expansion-fan region. On the basis of this analysis it is concluded that the linear theory does not in general give the correct limiting value for the velocity change across the expansion fan but, in practice, gives almost the correct shape for the jet boundary.
