Static Stability and Control Characteristics of Scissor Wing Configurations

Abstract

A scissor wing geometry is introduced as an alternative to variable sweep and oblique wing designs. It is shown that this configuration offers certain enhancements to the stability and control of the aircraft in addition to aerodynamic advantages associated with sweep. It is shown that a scissor wing configuration can maintain a constant static margin throughout its flight Mach numbers. The dependence of the motion of the aircraft neutral point on the sweep angle is shown to be a function of the chord and span ratios. The control authority is studied and shown not to suffer with changes in the sweep angle. It is also suggested that with the use of wing mounted elevons, additional pitch and attitude control can be obtained over a range of sweep angles.
