The results of theory/experiment correlative studies at subsonic and supersonic Mach numbers are presented in this paper. These studies were conducted by using theoretical design tools consisting of the Method of Characteristics, newly-developed integral compressible boundary-layer methods for infinitely swept wings, namely, laminar boundary layer with suction, prediction of neutral instability and transition due to amplification of Tollmien-Schlichting (T.S.) waves and crossflow (C.F.), and a method for predicting separating turbulent boundary-layer characteristics. Results of correlations have indicated that the present integral boundary layer methods are quite successful in predicting transition phenomenon both at transonic and supersonic speeds.
