Just curious
1 Attachment(s)
Hi guys.
I am just curious if any of you have seen this. This Eagle was making a high Gs turn and after snapping a few photos, I
noticed the skin on the wing wrinkled up under high G load. Compared it with another few pics I took of the same bird
at low speed, and there was no wrinkles. First time I have seen this. Thanks.

RE: Just curious
Easy: wings bend under load.......compression and tension on the upper/lower wing skin in a high G maneuver. Won't happen at low speed and commensurate low attainable G's
<div>As long as you don't "over G" the wing will not be damaged or permanentky bent.
The guy is likely pulling 6 or 7+ G's while in AB going around that corner......... Grunt!</div><div>

yep, seen it alot over the years.. all jets do it.. notice how wrinkled the under neath side of a B52 is.. when in the air, its smooth..

Wings do bend in compression, tension and torsion.....buckle ?...don't thinks so.....Send that photo to the air-force and let a structure expert decide. I remember a few years back when a F15 forward fuse separated during training

RE: Just curious
Strange that the wrinkles only appear closeto the the air separation point, and not evenly over the wing...!?

Could it be the high G turn/altered air density distorting the image caught by the camera lense?

Just thinking loud (again...my wife has told me not to;).....)
