A method for the transient analysis for the stationary cone was developed. Extensions of several methods were utilized and made compatible with existing flow conditions to provide a continuous flow solution. Whithams approximate solution was used to obtain the shock diffraction pattern past the forebody. The results of the blast-base interaction solution was used to mate the blast passage with the formation of the separated flow region behind the body. It is shown that the steady-state base flow studies of Zumwalt and Tang provided the method used to accomplish this. The use of Zumwalts conical wake analysis introduced a satisfactory physical model for the jet mixing region which occurs as a result of flow separation.
