Abstract:

an inviscid, compressible, linearized dissociating gas flow over slender bodies of general cross section is considered. Essentially it is an extension of the conventional slender body theory including the dissociation effects. Both supersonic and subsonic cases are examined. To our present approximation the lateral forces and moments are found the same as those for the conventional case, but there exist additional nonequilibrium terms in the drag expression. If the body is pointed at both ends, the nonequilibrium term is formally the same for both the supersonic and the subsonic cases except that the sign in the respective cases is just the opposite. Physical aspects of the nonequilibrium drag problem are briefly considered. These considerations show that in the subsonic case the nonequilibrium term represents a drag and in the supersonic case it is a thrust. The supersonic drag of slender bodies of revolution at small angle of attack has been calculated, including dissociatiion effects.
