Span efficiency of rectangular wing

WebThe aspect ratio of the wing, which is given the symbol , is defined as the ratio of the square of the wing span to the wing reference area, i.e., (7) The aspect ratio of a wing is important in aerodynamic analysis because a wing with higher aspect ratio generally is more aerodynamically efficient because it will have lower values of drag. WebIn subsonic flow, steeply swept and narrow wings are inefficient compared to a high-aspect-ratio wing. However, as the flow becomes transonic and then supersonic, the shock wave …
