An experimental study was conducted to determine the characteristics of control surfaces on low aspect ratio delta wings at subsonic Mach numbers. Included were parametric studies on control surface span, chord, and position, all of which were shown to have a significant effect on control surface performance. Comparisons were made with several low speed theories and it was demonstrated that the vortex lattice theoretical approach provided an effective means of calculating control surface characteristics on both the study models and on several realistic configurations, including the X-24B and two early advanced air defense interceptor concepts.
