WebClark Y is the name of a particular airfoil profile, widely used in general purpose aircraft designs, and much studied in aerodynamics over the years. The profile was designed in … Webairfoil lead to the new design airfoil which is known as KFm (Kline – Fogleman modified) airfoil. The step airfoil either at top (KFm2) or bottom (KFm1) surface or both side (KFm4) fall into this category. These steps can be use more than one time. For example; KFm3 [4] and KFm7 (fig. 7). When the flow passes through the step airfoil then WebDick is now 84 years old. Photo provided by Dick Kline. After the success of the paper airplane design, Floyd Fogleman, a modeler, expressed interest in the airfoil and built a large balsa model for testing. The aircraft flew like the paper airplane and resisted stalling, flew smoother, and glided longer than anything Floyd had ever seen. csslp study material

WebThis is why all basic trainers utilize a flat-bottom wing. Aerobatic trainers use more symmetrical wings because these airfoils develop the same amount of lift whether inverted or upright. This is good for aerobatic flight, but not usually required in a basic trainer. Semi-symmetrical airfoils have some airfoil shape on the bottom but a lot ...
