Wing Rock of Nonslender Delta Wings

That slender delta wings will experience wing rock is an established fact, and the responsible flow mechanism is well understood. However, the same flow mechanism could not cause wing rock of nonslender delta wings. Thus, the wing rock observed for a 45-deg delta wing must be generated by a different flow phenomenon. Experimental results for delta wings and airfoils are analyzed in order to define the flow mechanism driving the observed wing-rock motion
