Extract

This note illustrates the correlation of the pressure distributions measured on three NACA 16-series aerofoils at subsonic and transonic speeds. The transonic similarity parameters proposed by Spreiter

are used for the subsonic, transonic and supersonic types of flow illustrated in Fig. 1.
