WebWhether the aircraft gains, sustains, or loses altitude depends on lift, which in turn depends on airflow over the wings, which in turn depends on velocity. The faster the aircraft is travelling, the more lift is generated by the wings. Or, put another way, lift is a function of thrust, and is modified by weight and drag.

WebAn airplane has a high L/D ratio if it produces a large amount of lift or a small amount of drag. Because under cruise conditions lift is equal to weight, a high lift aircraft can carry a large payload. And because under cruise conditions thrust is equal to drag, a low drag aircraft requires low thrust. Thrust is produced by burning a fuel. WebThe lift/drag ratio increases very rapidly up to about 3 deg or 4 deg , at which angles the lift is nearly 24 times the drag (some aerofoils give an even greater maximum ratio of lift to drag); the ratio then gradually falls off because, although the lift is still increasing, the drag is increasing even more rapidly, until at the stalling angle the lift may be only 10 or 12 … Web2 de out. de 2024 · High aspect ratio wings are seen on sailplanes, and the best of these deliver lift to drag ratios of more than 60 to 1.
