Timeline for Can someone explain to me why these planes just don't turn about their center of gravity?

The first motion is part of the attitude dynamics, the second motion is part of the trajectory dynamics. | |

| Apr 14, 2015 at 21:49 | comment | added | jamesqf | @Federico: Ah, I think I misunderstood the question. I thought it was asking about rotation about the long axis of the fuselage (roll), rather than pitch. I guess the pitch answer just seems so intuitively obvious. | |

removed seaplane tag, as it is incorrect.

| Apr 14, 2015 at 14:48 | comment | added | Dave | @Federico I know I just thought I would mention that its not a plane mainly because i love how ekranoplan sounds :) | |
| Apr 14, 2015 at 14:46 | comment | added | Federico | @Dave yes, being a WIG will change the magnitude of the effect, but the principle is the same | |
| Apr 14, 2015 at 14:41 | comment | added | Dave | Just a note, this is not an airplane (or seaplane as its tagged) its a Ground Effect Vehicle en.wikipedia.org/wiki/Ground_effect_vehicle in particular this is a A-90 Orlyonok. GEV's have similar but different aerodynamics than an airplane as they are made to work only in ground effect. Some however can climb to significant altitude and they can all work over land as well as water. | |
