Book Description
Space Trajectories covers the proceedings of a symposium sponsored by the American Astronautical Society, Advanced Research Projects Agency, and Radiation Incorporated, held on December 14-15, 1959. The book focuses on the field of trajectory analysis, including orbital and trajectory computations, tracking of satellites, and the use of computer programs in space missions. The selection first tackles satellite and probe orbit determination, general survey of the field, and astrodynamics, as well as theoretical, computational, and operational problems, application to lunar orbits, and contributions of satellite observations. The book then examines trajectory constants and trajectory computation and optimization. Discussions focus on the classical method of orbital computation, effect of uncertainty on interplanetary orbits, masses, diameter, and flattening of planets, and determination of the physical constants of the moon. The manuscript takes a look at trajectory computation and optimization, trajectory computation in systems design, and computer programs for space missions. Topics include simulation and targeting programs, satellite tracking methods, direct numerical integration, classical methods of orbital computation, and references on trajectory computation and optimization. Space-born computer design, space maneuvers, and re-entry trajectories and problems of hypersonic flow are also mentioned. The selection is a valuable source of data for astronauts and readers interested in space trajectories.

Book Description
Sphere drag coefficients were measured in the Berkeley Low Density Wind Tunnel at Mach equals 2, 4, and 6, and free stream Reynolds numbers between 10 and 10,000 for both insulated and cold wall conditions. The measurements indicate that sphere drag in this regime is strongly dependent on the Reynolds number behind a normal shock wave, and only weakly dependent on Mach number. In addition, it was found that a decrease in wall temperature/stagnation temperature (T sub w/T sub o) from 1 to 0.26 was accompanied by a 5 - 10% decrease in the drag coefficient. A precision microbalance was used to obtain data for insulated spheres, and a moving model technique was used to obtain data for small spheres falling freely through a wind tunnel jet. These latter tests were performed using both cold and insulated models. The results on insulated spheres at M equal 2 and 4 were in good agreement with the measurements of other investigators. The results of the cold wall tests indicate that for Mach numbers greater than 5 in air, sphere drag coefficients are a function only of T sub w/T sub o and the post normal shock Reynolds number.

Book Description
Hypersonic Flow Theory presents the fundamentals of fluid mechanics, focusing on the hypersonic flow theory and approaches in theoretical aerodynamics. This book discusses the assumptions underlying hypersonic flow theory, unified supersonic-hypersonic similitude, two-dimensional and axisymmetric bodies, and circular cylinder. The constant-streamtube-area approximation, streamtube-continuity methods, and tangent-wedge and tangent-cone are also deliberated. This text likewise covers the similar laminar boundary layer solutions, bluntness induced interactions on slender bodies, and free molecule transfer theory. The dynamics of hypersonic flight or hypersonic wing theory, magnetohydrodynamic theory, or any developments involving treatment of the Boltzmann equation are not included. This publication is intended for hypersonic aerodynamicists, students, and researchers conducting work on the hypersonic flow phenomena.

Book Description
Since the publication of the first edition of Multiphase Flow with Droplets and Particles, there have been significant advances in science and engineering applications of multiphase fluid flow. Maintaining the pedagogical approach that made the first edition so popular, this second edition provides a background in this important area of fluid mecha
