Abstract

IN a recent article by the author, reference was made to the stalling of airscrew blades and to some of its effects. It seems worth while to examine more closely the kinematics of stalling. In some cases the thrust coefficient graph for a chosen value of p/D indicates a marked drop in kT at a certain value of J, this drop being attributed to stalling of the blade; point ? on ABC (Fig. 1) is such a point. It seems certain that the effect of stalling is complete at C when the kT graph is practically parallel to the J axis, but where the effects of stalling first come into play is not so clear. In other cases, especially for lower values of p/D, the kT graph has the shape DE, from which it is not clear whether or not any stalling at all has taken place.
