of the effects of variations in tip shape, aspect ratio, flap setting, stagger, gap, decalage, sweepback, and airfoil profile. The arrangements represented most of the types of wing systems in use on modern airplanes. The effect of each variable is illustrated by means of groups of curves. In addition, there are included approximate autorotational characteristics in the form of calculated ranges of "rotary instability."

A correction for blocking in this tunnel which applies to nlonoplanes at large angles of attack has been developed, and is given in an appendix.
