Book excerpt: An implicit finite-difference scheme is developed for the fully coupled solution of the viscous, radiating stagnation-streamline equations, including strong blowing. Solutions are presented for both air injection and injection of carbon-phenolic ablation products into air at conditions near the peak radiative heating point in an earth entry trajectory from interplanetary return missions. A detailed radiative-transport code that accounts for the important radiative exchange processes for gaseous mixtures in local thermodynamic and chemical equilibrium is utilized in the study. With minimum number of assumptions for the initially unknown parameters and profile distributions, convergent solutions to the full stagnation-line equations are rapidly obtained by a method of successive approximations. Damping of selected profiles is required to aid convergence of the solutions for massive blowing. It is shown that certain finite-difference approximations to the governing differential equations stabilize and improve the solutions. Detailed comparisons are made with the numerical results of previous investigations. Results of the present study indicate lower radiative heat fluxes at the wall for carbon-phenolic ablation than previously predicted.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1974 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: Curve-fit formulas are presented for the stagnation-point radiative heating rate, cooling factor, and shock standoff distance for inviscid flow over blunt bodies at conditions corresponding to high-speed earth entry. The data which were curve fitted were calculated by using a technique which utilizes a one-strip integral method and a detailed nongray radiation model to generate a radiatively coupled flow-field solution for air in chemical and local thermodynamic equilibrium. The range of free-stream parameters considered were altitudes from about 55 to 70 km and velocities from about 11 to 16 km.sec. Spherical bodies with nose radii from 30 to 450 cm and elliptical bodies with major-to-minor axis ratios of 2, 4, and 6 were treated. Powerlaw formulas are proposed and a least-squares logarithmic fit is used to evaluate the constants. It is shown that the data can be described in this manner with an average deviation of about 3 percent (or less) and a maximum deviation of about 10 percent (or less). The curve-fit formulas provide an effective and economic means for making preliminary design studies for situations involving high-speed earth entry.
