Book Description
An approximate inverse solution is presented for the nonequilibrium flow in the inviscid shock layer about a vehicle in hypersonic flight. The method is based upon a thin-shock-layer approximation and has the advantage of being applicable to both subsonic and supersonic regions of the shock layer. The relative simplicity of the method makes it ideally suited for programming on a digital computer with a significant reduction in storage capacity and computing time required by other more exact methods. Comparison of nonequilibrium solutions for an air mixture obtained by the present method is made with solutions obtained by two other methods. Additional cases are presented for entry of spherical nose cones into representative Venusian and Martian atmospheres. A digital computer program written in FORTRAN language is presented that permits an arbitrary gas mixture to be employed in the solution. The effects of vibration, dissociation, recombination, electronic excitation, and ionization are included in the program.

Book Description
Space Activity: Impact on Science and Technology contains the proceedings of the 24th International Astronautical Congress held in the USSR on October 7-13, 1973. Contributors focus on the contribution of space research to the development of science and technology, including biology and medicine. This text begins with a discussion on the role played by Soviet automatic vehicles in the progress of space automatics and control theory. The discussion then turns to the problems of space technology and their implications for science and technology, industrial applications of aerospace technology, and development of liquid-propellant rocket engineering technology in the USSR. The chapters that follow explore the contribution of space medicine to public health; the role of astronautics in the development of methods of celestial mechanics; the flight performance of the unmanned Skylab space station; and remote sensing of the environment and earth's resources studies from Soviet manned spacecraft. The book concludes with an appraisal of international standards for model rocket engines. This book will be of interest to students of astronomy as well as researchers and practitioners working in the field of space exploration and research.
