Shaping the wing like an airfoil reduces its drag and allows it to reach a greater angle of attack without stalling, but the airfoil shape is not indispensable—it’s a refinement. Angle of ...

Whether the flow is viscous-drag dominated or pressure-drag dominated depends entirely on the shape of the body. A streamlined body looks like a fish, or an airfoil at small angles of attack, whereas ...

This can be achieved by using an airfoil (wing) profile, which is a shape with very low drag. I made and fitted two external ...

The exact airfoil shape of a wing has a massive effect on the performance and efficiency of an aircraft and will be selected based on the intended flight envelope. If you’re moving beyond foam ...
