How does the aspect ratio of a wing affect lift coefficient?

The aspect ratio of a geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, when the rectangle is oriented as a "landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal fraction. The values x and y do not represent actual widths an… WebNov 5, 2012 · 2. This is just a hypothesis: but there is probably not one "preferred" aspect ratio, even for one individual. It probably has to do with the following points: 1. the eyes are positioned on a horizontal line; 2. the width between the irises; 3. how far you are looking. And let's not call it a "preferred" aspect ratio.
