What variables can you change to affect flight?ĭrag is air resistance, the force that is working against the blades, causing them to slow down.You want to design your blades so that they have as little drag as possible.ĭrag increases with the area facing the wind. How does the shape of the blade affect the ability to go higher? It uses a php script to convert all the airfoils from the UIUC Airfoil Coordinates Database (about 1550 or so ) to scad and stl files. The 15 indicates that the airfoil has a 15% thickness to chord length ratio: it is 15% as thick as it is long.This tutorial is based on the work of members of La Crosse Inventers Guild. The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. įor example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord.
