Book excerpt: This report presents the results of tests which are part of an experimental hypersonic research program designed to support an investigation of new theoretical means for the prediction of pressures on attached-shock configurations at hypersonic speeds. The data obtained include six-component force data at Mach 8 for seven configurations which were previously pressure tested at Mach 5 and 8 under the original program. The force tests were run in tunnel B of the Von Karman Facility of the Arnold Engineering Development Center. The ranges of test variables were: angle of attack, -10 degrees to 20 degrees; angle of yaw, -3 degrees to 15 degrees; Reynolds number per foot, 0.8 and 2.0 x 10(superscript 6). Data were also obtained at a nominal Mach number of 21 for three pressure instrumented configurations tested earilier at Mach 5 and 8 under the original program. The tests were run in tunnel HS-2 of the Von Karman Facility. Pitch data were measured over the angle of attack range -5 degrees to 20 degrees at a Reynolds number per foot of approximately 4X10(superscript 6). Some of the measured pressures are compared with thin-shock-layer thoery, Newtonian pressure formula, equivalent-cone and tangent-wedge approximations with the thin-shock-layer theory being generally superior in appropriate applications.

Book excerpt: This report presents the results of an experimental hypersonic research program specifically designed to support an investigation of new theoretical means for the prediction of pressures on attached-shock configurations at hypersonic speeds. An analysis of the data is presented by comparison with the thin-shock-layer theory and the improved shock-expansion theory developed in the analytical program as well as with some of the simplified methods in current favor such as Newtonian, tangent-wedge, equivalent-cone, and shock-expansion methods. It is shown that in appropriate applications the thin-shock-layer theory is superior to any of these simplified methods. However, test conditions did not duplicate those necessary for complete evaluation of the improved shock-expansion theory. In certain instances the influence of viscous phenomena on the results is discussed, especially with regrad to the distinct wing-body combinations. A modified technique for taking vapor screen photographs developed in the course of these tests was found to be particularly helpful in this connection. The pressure tests on the sharp leading-edge wings, bodies, and wing-body combinations wer conducted at M̃5 and 8 in tunnels A and B of the Von Karman Facility of the Arnold Engineering Development Center. The range of test variables were: angles of attack, -10 degress to 20 degrees; angles of yaw, -15 degrees to 15 degrees; Reynolds numbers, 0.83 to 6.0 x 10(superscript 6)/ft.

Available in PDF, EPUB and Kindle. Book excerpt: Progress in Aeronautical Sciences, Volume 6 reviews advances in aeronautical sciences and considers a wide range of problems related to aerodynamics, including some classical problems of fluid motion and those affecting hypersonic aircraft. Topics covered range from equations of gas flow at low density; nonequilibrium expansion flows of dissociated oxygen and ionized argon around a corner; and the role of spatially growing waves in the theory of hydrodynamic stability. This volume is comprised of five chapters and begins with a discussion on flows of gases where the density of the gas is too low for equations of continuum gas dynamics to be applicable. The kinetic theory of gases is used to derive the equations governing such flows. The second chapter deals with the nature of shock waves in flows of electrically conducting gases subjected to magnetic fields. The third chapter is concerned with the theory of two-dimensional flows of dissociated oxygen or ionized argon expanding around a corner. The fourth chapter goes back to the classical problem of hydrodynamic stability and the possible mechanics underlying the transition from the laminar to a turbulent state of the flow. The last chapter describes a future type of aircraft that can fly at hypersonic speeds. This book will be a useful resource for students and practitioners in the field of aeronautics.

Available in PDF, EPUB and Kindle. Book excerpt: A computational technique, called the method of lines, is developed for computing the flow field about conical configurations at incidence in a supersonic flow. The method, which makes use of the self-similarity property, is developed for the nonlinear flow equations. The method has proved to be an efficient and versatile procedure for constructing the numerical solutions to conical flow problems. It has been successful in computing the flow about circular and elliptic cones at conditions where small regions of supersonic cross flow develop and for the conical delta wings where the region of supersonic cross flow is extensive. The calculations made for circular and elliptic cones as well as for the compression side of various conical delta wings are in good agreement with experiment except in regions where viscous effects become important.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers classical and modern aerodynamics, theories and related numerical methods, for senior and first-year graduate engineering students, including: -The classical potential (incompressible) flow theories for low speed aerodynamics of thin airfoils and high and low aspect ratio wings. - The linearized theories for compressible subsonic and supersonic aerodynamics. - The nonlinear transonic small disturbance potential flow theory, including supercritical wing sections, the extended transonic area rule with lift effect, transonic lifting line and swept or oblique wings to minimize wave drag. Unsteady flow is also briefly discussed. Numerical simulations based on relaxation mixed-finite difference methods are presented and explained. - Boundary layer theory for all Mach number regimes and viscous/inviscid interaction procedures used in practical aerodynamics calculations. There are also four chapters covering special topics, including wind turbines and propellers, airplane design, flow analogies and hypersonic (rotational) flows. A unique feature of the book is its ten self-tests and their solutions as well as an appendix on special techniques of functions of complex variables, method of characteristics and conservation laws and shock waves. The book is the culmination of two courses taught every year by the two authors for the last two decades to seniors and first-year graduate students of aerospace engineering at UC Davis.
