Hello,
I have been watching a lot of Aircrash Investigations (also called Mayday) and it has gotten me interested in aerodynamics.
I'm curious about what force would be needed to tip a plane over? Say that there was a sudden upwards gush of wind on the end of one wing (I am familiar with the concepts of torque) then the force on each wing would be out of balance and, if strong enough, could roll the plane over.
I'm really curious as to if this is at all possible or would the necessary force from the wind just be ridiculously high. I'm not sure how to calculate it though.
Google says that a boeing 747 weighs about 396,890 kg at max takeoff weight (so roughly 400,000 kg So that means gravity is pushing down with roughly 4,000,000 N. The plane is then generating the same amount of force but in the upwards direction for level flight. If the wings both generate all of the left (I know this isn't true but they generate most of it yeah?) then that's 2,000,000 N upward on each wing.
That gives me some ballpark figures. I'm curious as to how much of a difference in force would be required to tip the plane over.
