DOWNLOAD EBOOKA two-stage-to-orbit (TSTO) spaceplane concept developed in 1993 is revisited, and new information is provided to assist in the development of the next-generation space transportation vehicles. The design philosophy, TSTO spaceplane concept, and the design method are briefly described. A trade study between cold and hot structures leads to the choice of cold structures with external thermal protection systems. The optimal Mach number for staging the second stage of the TSTO spaceplane (with air-breathing propulsion on the first stage) is 10, based on life-cycle cost analysis. The performance and specification of a prototype/experimental (P/X) TSTO spaceplane with a turbo/ram/scramjet propulsion system and built-in growth potential are presented and discussed. The internal rate of return on investment is the highest for the proposed TSTO spaceplane, vis-A-vis a single-stage-to-orbit (SSTO) rocket vehicle and a TSTO spaceplane without built-in growth. Additional growth potentials for the proposed spaceplane are suggested. This spaceplane can substantially decrease access-to-space cost and risk, and increase safety and reliability in the near term It can be a serious candidate for the next-generation space transportation system.

DOWNLOAD EBOOKThe renewed interest in high-speed propulsion has led to increased activity in the development of the supersonic combustion ramjet engine for hypersonic flight applications. In the hypersonic regime the scramjet engine's specific thrust exceeds that of other propulsion systems. This book, written by a leading researcher, describes the processes and characteristics of the scramjet engine in a unified manner, reviewing both theoretical and experimental research. The focus is on the phenomena that dictate the thermo-aerodynamic processes encountered in the scramjet engine, including component analyses and flowpath considerations; fundamental theoretical topics related to internal flow with chemical reactions and non-equilibrium effects, high-temperature gas dynamics, and hypersonic effects are included. Cycle and component analyses are further described, followed by flowpath examination. Finally, the book reviews experimental and theoretical capabilities and describes ground testing facilities and computational fluid dynamics facilities developed for the study of time-accurate, high-temperature aerodynamics.

DOWNLOAD EBOOKA revolution in spaceflight is likely soon with the prospect of everyday access to orbit within fifteen years. Costly launch vehicles based on ballistic missiles will be replaced by ‘spaceplanes’, using technology that exists today. In five years' time, a prototype could be built, and with a further ten years of detailed development, the design could approach airliner maturity, reducing the cost of sending people into space some one thousand times to around US$20,000.Spaceplane development has, in effect, been suppressed by entrenched thinking and short-term vested interests. But the present monopoly of large government space agencies is becoming unsupportable, and the market that understands the very real opportunities for space travel will be reaching critical mass in the near future.This book examines these issues and shows why space tourism will one day become the single largest business in space, and how astronomy and environmental science will be transformed by low-cost access making possible instruments vastly larger than those of today.
