I'm working on a new F-16 model for Falcon 4 and I have a question about the rudder. When rudder is applied it cuts into the tail (rudder moves inside). How is this avoided? Is the cover plate between the red lines flexible? Or is the rudder near the black line a bit more inside?



Maximum deflection of 30 degrees.

The cover plate between the red lines is a thin aluminum rudder seal that is attached to the tail. The strip you see between the red line and the black line is also a thin aluminum rudder seal that is attached to the rudder. The forward part of that seal is curved. It's hard to see the curvature in the photo. The curved seal on the rudder slides under the seal attached to the tail.

It's also hard to see, but the rudder itself is actualy hinged not in the midle of the tail, but a bit to the right. That means that the seals on the right side a kind of more bend than slide into each other. If closely look't, you might see slidemarks on the left side seals, but hardly any on the right side...
