The aircraft appears to be at a relatively high AOA based on the leading edge devices. Coupled with the rather significant deflection of the 'rudders' and 'ailerons' it seems that we're seeing a picture of the aircraft in a fairly high performance posture (roll to the right?). This was the exact reason I posted it!!, I would assume it cocks the low RCS right up when the fence/air spill panel is open. that said, it is ontop of the airframe so its exposure to a _single_ enemy would be minor. Whats the usual reasons for having such a panel?, is it to stop umwanted airflow on the air spill port at High AoA, it seems (to my untrained eye) to be a bit of a hack on a stealth aircraft! They were even there on the prototypes so I'm inclined to think it's not so much a hack as it is a solution to an unusual problem. The fact that they're rotated 90s from those on the prototypes suggests that the area got a lot of attention during developement and it apparently still seemed the best way to go. The dogtooth on the Eagle's horizontal stab and the fences on the Hornet's strakes are hacks. The spoilers on the F-22 seem to have been there from the very beginning. |
