The Unsteady Compressible Flow with Rotational Symmetry,
Abstract
In order to investigate the effect of chambrage on the gas flow in the explosive chamber of a gun, a study of three dimensional flow with rotational symmetry was undertaken. It is known that, for gun barrels of limited length, missile speeds can be increased by enlarging the explosive chamber and by improving the contour of the chamber where it leads into the barrel. The equations for unsteady compressible isentropic flow, using a perfect gas, were expressed in terms of characteristic surfaces. The properties of these characteristic surfaces and characteristic grids are discussed. A relationship between the dependent variables for each characteristic surface was established which constitutes a 'linkage' system. By means of this 'linkage' system equations are set up which make it possible to obtain the solution of the flow by means of a numerical integration. (Author)
