Wheels effect upon touchdown
-
just thought about this again and not quite sure if I have a good answer as to why it happens but it is all what I was able to do for now, here it goes. Why would the jet’s nose point in the direction of the wind? it’s because viewing it from the top the jet experiences a rotation since the wind force at the tail is larger than the nose. But why does the rotation stops at some finite angle? because the wind force is directly proportional to the tail area, and the rotation will reduce the tail area until the wind’s force equals component of the thrust opposite to the wind. So what happens at touch down? the friction from the wheels are in the same direction as the thrust (forward) causing the nose to rotate downwind which will immediately increase the tail area and thus the wind force.
