An airfoil system includes an airfoil body and at least one flexible strip. The airfoil body has a top surface and a bottom surface, a chord length, a span, and a maximum thickness. Each flexible strip is attached along at least one edge thereof to either the top or bottom surface of the airfoil body. The flexible strip has a spanwise length that is a function of the airfoil body's span, a chordwise width that is a function of the airfoil body's chord length, and a thickness that is a function of the airfoil body's maximum thickness.
1. An airfoil system, comprising; an airfoil body having a flap coupled to a main body at a flap separation, wherein said main body comprises a top surface and a bottom surface, and said airfoil having a chord length C, a span S, and a maximum thickness TMAX;a flexible strip comprising at least one edge and having a spanwise length that is approximately 0.5S to 1.0S, a chordwise width that is approximately 0.05C to 0.2C, and a thickness that is approximately 0.01TMAX to 0.05TMAX;wherein said flexible strip is attached to said top surface along said at le...
