Diffraction of a planar strong detonation wave by a moving three-dimensional thin body

An analytic solution is obtained for the diffraction of a planar strong detonation wave by a three-dimensional thin body moving in the opposite direction. The planform and the thickness distribution of the body can be arbitrary and the speed of the body can be either supersonic or subsonic relative to the undisturbed stream ahead of the wave or to that behind the wave. The solution is a generalization of the previous solution of Ting and Gunzburger for the shock diffraction.
