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.

Weba lift/drag ratio of 13. Fig. PF 4.5. The line which is the tangent to the polar curve represents the best lift/drag ratio. In this example the best lift/drag ratio is 13, that is; the lift is 13 x the drag. The best lift/ drag ratio for normal light aircraft is typically between 15 and 20 depending on several factors concerning the wings. WebIf you need to have a low aspect ratio on your ultralight airplane wing in order to save weight, then you may want to figure out how to reduce the lift drag ...

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. A 60-degree sweep pure delta wing has an aspect ratio of ~2.3, compared to a sailplane which might have an aspect ration of 30, or a typical airliner, which might have an aspect ratio of 9.5. Web17 de dez. de 2011 · They learned from their wind tunnel tests the important effect of wing aspect ratio on the lift and drag. (For their rectangular wings, the aspect ratio is equal to the wing span divided by the chord. A large aspect ratio wing is like a slat from a Venetian blind; a low aspect ratio wing is short and stubby.) Their 1900 and 1901 gliders had low ...

Mathematically, the maximum lift-to-drag ratio can be estimated as: where AR is the aspect ratio, the span efficiency factor, a number less than but close to unity for long, straight edged wings, and the zero-lift drag coefficient. Most importantly, the maximum lift-to-drag ratio is independent of the weight of the aircraft, the area of the wing, or the wing loading.
