Why are downward pointing winglets more efficient?
Jul 8, 2017 · While most aircraft have upward-pointing winglets Source there are also some UAVs (I couldn't find any manned aircraft$^1$) with downward pointing winglets. Source I'm pretty …
Why is the nose cone of Russian fighters pointing slightly down?
Let's take the Sukhoi Su-30 as an example: The nose cone is clearly pointing a bit downwards with respect to the level of the engines and wings. Why is this? How can this kind of banana …
Why is there a difference between aileron upwards and …
When deflected at the maximum angle maximum angle downwards is lower than when deflected upwards. I suppose that this is due to the fact that when the wing has to be deflected upwards …

Oct 22, 2018 · If the lift were less than the weight of the aircraft, then the aircraft would be accelerating downwards. The only times that lift is not equal to weight are the times when the …
aerodynamics - Can a wind gust below the rotor affect the lift …
May 1, 2024 · The rotor produces lift by accelerating air downwards. The air mass then proceeds down, and in ground effect is diverted sideways, when out of ground effect, it continues …
aerodynamics - What causes lift? - Aviation Stack Exchange
Jul 7, 2022 · Note that lift can only happen if the upper contour of the wing will slope downwards and away from the initial path of the air flowing around the wing's leading edge. This could …
