Lateral location of the center of pressure

Question

I am working on a simple flight simulator. For this, I need to calculate aerodynamic forces and apply them to the aircraft. As I understand it, lift and drag act through the wings center of pressure.

Unfortunately, all the information that I have found so far only talks about the location of the center of pressure in relation to the chord and the airfoil. Something like this:

So my question is, where would the CoP be located along the length of the wing? Say I model the aircraft as having two main wings, where would the lift force be applied? Would it be in the center of wing? I know that the location forward or aft on the wing depends on the airfoil.

Answer 1

What is being referred to in the 3rd dimension is lift distribution.

This has several practical applications in wing design because torque stress on the main wing spar increases with distance from the center of gravity if 2 dimensional lift remains the same along the entire wing.

Some choose to taper the wing, as sea gulls do, to lessen the strain on the wing during, for example, a high G maneuver.

Another clever way is to "wash out" the wing tips a few degrees, which, along with a little sweep, creates very desirable pitch stability up to and including stall, as well as creating the sought after "elliptical lift distribution".

Both wing torques should be identical (with respect to the center of gravity). Aileron controls create an imbalance, causing the aircraft to roll.
