Why is there a difference between aileron upwards and downwards . . . 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 and consequently the aileron moves downwards, the force required is lower as there is already lift being produced by the wing whereas the opposite would happen
What is the principle behind flight of airplanes? [duplicate] The downwards movement of the air is achieved by two methods, both of which are used on airplanes: The leading edge of the wing is higher than the trailing edge, making the wing act as a wedge The angle between the line from leading edge (front edge of the wing) to the trailing edge (rear edge of the wing) and the airflow coming towards the
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 even fly
aerodynamics - Why do airfoils trailing edges point downward . . . The same is true for control surfaces: Depending on the desired lift change, their trailing edge will point up- or downwards See below for an example where I plotted the pressure distribution for three flap deflections in one graph Upper and lower surface pressure are shown by color-coded lines, and lower lines belong to the lower surface
aerodynamics - Does the downwash created by induced drag increase or . . . According to the theory I know, lift is produced by accelerating air downwards at the trailing edge Hence, as downwash increases so does lift Hence, as downwash increases so does lift Induced drag is due to vortices at the wing tips and they also create downwash
Why are downward pointing winglets more efficient? 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
Are wings any more efficient at creating lift, versus orienting the . . . The suction on the upper surface pulls the air above the wing down and the pressure on the lower side pushes more air down As a result, the air is accelerated downwards when it flows off the wing Yes, airplanes fly by pushing air down; this is not a simplification but a consequence of the pressure field around a wing or helicopter rotor
Why are the guns on the AC-130 not mounted on the underside of the . . . Having guns point downwards will have the guns point away from the target (due to banking) when loitering Making it unsuitable to be used as a flying artillery position and forcing it to behave like a bomber (flying, reusable "bullet shell"*)
