The dragon would have a very shallow and wide profile much like a manta ray but this might fit the question. The up and down strokes of the wings will be very different than anything on earth. If you had the shoulder girdle fused, with the upper wing bone with a very small range of motion, the muscles of the torso would work to torque the upper wing bone(our humorous bone), rotating the lower wing in your up and down motions(elbow to wrist), this portion of the wing will be short and stout compared to what we usually picture as a wing. The vast majority of the wings surface area and lift power will be the "hand" much like a bat. Any thoughts and possible problems with this?

Btw a special system of tendons would likely be needed to transfer the great force down out to the wingtips to prevent your dragons light weight skeleton becoming pulverized.
