Aircraft engineering question?

Question

for an aeroplane weighing 5000kg undergoing a manoeuvre resulting in a load factor of 2.5, how much lift must the wing produce?

mu_huckleberry! Wow you're a very intelligent person aren't you?! This is an aircraft engineering question by the way, which means it requires a technical answer; you might want to look 'technical' up in the dictionary.

Answer 1

If the aircraft is pulling a load factor of 2.5 then the wing must produce 2.5*5000 kg or 12500 kg.

Answer 2

An aeroplane undergoing a maneuver that results in a load factor of 2.5 likely is changing direction causing g-loads (the pilot may be pushed into his seat as though the earth's gravitational attraction was 2.5 times stronger. This may have little to do with lift as the maneuver is temporary and the plane may gain or lose altitude by slipping through the air (as opposed to a ride on a roller coaster). The "lift" should not overload and fail the wings where lift relates to force "up" relative to the cockpit rather than up relative to the ground. Lift is derived from speed and aerodynamics and may differ from g-forces caused by rate of change in direction.

Answer 3

enough to fly the plane and keep it from hitting the ground and disinigrating into a million pieces, by the way, how many pieces will the plane break into when the lift is wrong?

Answer 4

what kind of manoeuvre you're talking about?
banking by how many degree?
what's the velocity?

you can find it in detail in "Airframe Structural Design" by Michael CJ Niu.
