Do your wings break easier swept or unswept

[Love_Beam]

Or does it matter at all? It seems to me that swept they break with less g's then unswept.

Logic would dictate that swept wings would be more resilient to snapping off with G than un-swept...but the way HB have implemented it is anyones guess. I am sure they have drawn upon their 'SMEs' input and experience regarding snapping off their wings in flight so they have some good realistic data to work with.

If not, I would be interested to see the fatigue tables and possible FEA data/stress analysis calcs they have used to determine the failure of the wing structure.

So my amateur theory is..

 

 

when the wings are swung back the lifting forces are twisting the joint as apposed to when they are forward they are applying force vertically across the air-frame

You need to have the ability to pull, let's say, 12+ G to get the wings to come off. Aerodynamics does not let you do that when you are slow (say Mach 0.7 and below), which is also when your wings are forward, so I imagine it's easier to screw up and snap the wings when they are swept back.

uh... what a strange question. It's like asking how big of a crater can you make crashing your plane.

 

I snapped my wings one so far while trying to get jiggy with an amraam, but only because I am not flying it for real (and because it is a tomcat) that I was able to do this.

 

Is there any record of an actual pilot snapping it's wings?

Fair point, as I mentioned I would be interested to see the specific manufacturer stress reports that deal with this situation. I regularly refer to Lockheed stress reports for several aircraft day to day but don't have access to Grumman ones. I am sure all the loads were meticulously calculated during initial design.

Enough pressure on the wings from extreme lift forces would snap the internal wing structure, so in whatever position where you are able to go past its extreme point. You will be more likely to snap it when more swept because of less distribution of lift forces on the body of the wing, meaning less wing area.
