THE APPROXIMATE EXTERNAL AND INTERNAL FLOW PAST A QUASI-CYLINDRICAL TUBE MOVING AT SUPERSONIC SPEEDS

摘要: By using the Heaviside operational method applied to linear perturbation theory for supersonic flow past a cylindrical tube of nearly constant radius at small incidence, aerodynamic force and moment coefficients resulting from fluid pressure have been calculated outside tube, inside length (Ml—l)t times diameter where Mo is Mach number undisturbed flow. The results are obtained in form suitable computation. expressions drag, lift, involve only slope meridian section any point, angle certain auxiliary functions which same all shapes. distribution velocity components has considered theory; singularities discontinuities occur these components, or their derivatives, corresponding discontinuous change curvature respectively or, entry, streamlines bounding entering tube. nature studied.
