Notes on the Stability and Control of Tailless Airplanes

Abstract

Problems involved in stability and control of tailless airplanes are analyzed. Such factors as location of aerodynamic center and its effect on longitudinal stability, longitudinal trim with high-lift devices, effects of various changes in shape of wing on lateral stability, and effects of nacelles are covered. Sufficient stability and controllability can be secured without sweepback. With sweepback, a flap over center section of wing may be used to serve dual purpose of elevator control and high-lift device. Sweepback introduces undesirable stalling characteristics and may require auxiliary devices to prevent stalling of tips.
