So, a variable-sweep wing is an interesting design, but I am wondering: if the aircraft wing moves back or forward, then the payload's angle will also change. Is there a another rotating mechanism in the payload rack or wing to keep the payload straight?
For example, as demonstrated in this picture of a Tornado ADV where the red lines are payloads. When the wing goes back it also changes the angle of the payload, unless there is another mechanism to keep the payload straight.
However, some might argue that payload isn't carried on the variable part of the wing, as on the F14 (See the link for reference).
