LOW-SPEED INVESTIGATION OF THE EFFECTS OF FREQUENCY AND AMPLITUDE OF OSCILLATION IN SIDESLIP ON THE LATERAL STABILITY DERIVATIVES OF A 60 DEGREE DELTA WING, A 45 DEGREE SWEPTBACK WING, AND AN UNSWEPT WING

Abstract

This investigation was made for values of the reduced-frequency parameter of 0.066 and 0.218 and for a range of amplitudes from plus or minus 2 degrees to plus or minus 6 degrees. The results indicated that the effect of frequency manifests itself mainly in the high angle-of-attack region and that the 60 degree delta wing exhibited the largest effect, whereas the unswept wing exhibited the smallest effect.
