Dual-Wing Systems with Decalage Angle Optimization
Dual-Wing general aviation designs are studied and compared with single-wing designs. It is demonstrated that with proper selection of gap, stagger, decalage, and mission requirements, total drag can be significantly reduced. Proper spanwise distribution of decalage is shown to enhance efficiency while raising the critical Mach number. Also, flight conditions have been chosen to result in operation at the proper Reynolds number, reducing the viscous drag even further.
