From all the missiles/guide bombs I have come across, I've always observed that a symmetric airfoil is used for both the wing and tail.
Why not have a cambered airfoil for the wing and a symmetric airfoil for the tail? It would provide a better range for the missile/guide bomb.
If an airfoil were to be selected for X-tail missile/guide bomb configurations, what is the selection criteria? I'm trying to better understand the reason for this generally accepted design decision.
Any answers/suggestions would be appreciated.
