Title

Aerodynamic Investigation of Twist and Cant Angles for Joined Wing Transport Aircraft

Abstract

Joined wings constructed using the NASA NLF2-0415 natural laminar flow airfoil are investigated for various twist and cant angles of the aerodynamic/structural wings interconnect. The analysis was conducted using an aerodynamic panel code, PMARC. Configurations with the proper twist and cant angles are found that have total lift over drag ratios that exceed that of the single wing configuration having a higher aspect ratio than the joined wing configurations. Additional results indicate that even higher aerodynamic efficiencies can be achieved for the joined wing with further cant angle modifications.
