Motorcycle Knee & Shin Guards Easy to install Includes double tape method, no modification needed, and won't damage the original paint. Sold in pairs. No modifications or trimming required. Simply remove the stock air deflector and keep the original nuts for installation of the new fairing side covers. When air flows around a moving object, it accelerates due to the longer flow path around the object. For winglets, this accelerated airflow around the curved nose of the fairing enhances lift generation, which increases with the square of the airspeed. The design applies advanced aerodynamic principles to address downforce, utilizing vortex lift. On aircraft like the F-16, rotating vortices generated from wing extensions create low-pressure cores above the wing, significantly increasing lift at high angles of attack. This principle is adapted to improve stability and control. Due to safety constraints on winglet length, designers use multiple airfoils in a stacked configuration. Each airfoil contributes to downforce by redirecting airflow upward efficiently.
