Background
Wing-tip devices are widely implemented on low-wing, turbofan airliners in order to reduce lift-induced drag, thus improving aerodynamic efficiency. These devices were originally developed on traditionally cambered airfoils, and several modern studies maintain that design choice. It is hypothesized by the author that the combinative utilization of supercritical airfoils and several wing-tip technologies will yield distinct aerodynamic improvements with regards to winglet variety in contrast to conventional wing and winglet combinations preceding supercritical airfoil implementation.

Wing-tip devices are widely implemented on low-wing, turbofan airliners in order to reduce lift-induced drag, thus improving aerodynamic efficiency. These devices were originally developed on traditionally cambered airfoils, and several modern studies maintain that design choice. It is hypothesized by the author that the combinative utilization of supercritical airfoils and several wing-tip technologies will yield distinct aerodynamic improvements with regards to winglet variety in contrast to conventional wing and winglet combinations preceding supercritical airfoil implementation.
Two experimental methods were utilized to substantiate the author’s hypothesis:
1. CFD Simulation (ANSYS Mechanical, Fluent)
• Lift and drag force, coefficients, CL / CD , and center of pressure (CoP)
• Vortical structure generation
2. Wind tunnel testing (subsonic, open-loop configuration)
• Lift and drag force, coefficients, CL / CD
