This channel is dedicated to learning how to make model airplanes that fly, with a specific emphasis on designing planes. Aerospace engineering concepts are explored and demonstrated using simple free-flight gliders that are affordable and easy to build.
Stepped Airfoils for Model Airplanes - Are They Better?
This video proposes that at low Reynolds numbers, stepped airfoils can be more efficient that smooth airfoils by reducing excess skin friction drag. A simple experiment is conducted using model free-flight gliders made from foam board to demonstrate that small model airplanes equipped with KFM-2 and KFM-3 airfoils have potential to fly significantly further than those equipped with smooth airfoils.
