This thesis describes a number of issues associated with waverider configured spacecraft designed for interplanetary missions. The first such issue is the determination of the magnitude of the energies and velocities required for conventional gravity-assist (GA) spaceflight maneuvers contrasted with energies and velocities required for less conventional aero-gravity assisted (AGA) maneuvers for interplanetary spaceflight travel These comparisons will be made for an Earth-Mars shuttle mission, a mission to Saturn, a mission to Neptune, and a round-trip mission to Saturn. Two additional issues considered for each mission are the fuel requirements and flight time parameters for both gravity-assist and AGA maneuvering spaceflight trajectories. This research includes the use of the patched conic interplanetary trajectory optimization MIDAS (Mission Design and Analysis Software) code for mission flight path analysis developed by the Jet Propulsion Laboratory. Waverider configuration development and off-design aerothermal analysis for each mission was supported by the NASA Ames Research Center's Waverider code (a subset of the Hypersonic Aircraft Vehicle Optimization Code) and a modified AEROSA code employing a Martian atmosphere, respectively. The results of this research showed that by using AGA, launch windows could be widened, flight times could be reduced by 25%, and fuels could be reduced by 30%.

In the aviation field there is great interest in high-speed vehicle design. Hypersonic vehicles represent the next frontier of passenger transportation to and from space. However, several design issues must be addressed, including vehicle aerodynamics and aerothermodynamics, aeroshape design optimization, aerodynamic heating, boundary layer transition, and so on. This book contains valuable contributions focusing on hypervelocity aircraft design. Topics covered include hypersonic aircraft aerodynamic and aerothermodynamic design, especially aeroshape design optimization, computational fluid dynamics, and scramjet propulsion. The book also discusses high-speed flow issues and the challenges to achieving the dream of affordable hypersonic travel. It is hoped that the information contained herein will allow for the development of safe and efficient hypersonic vehicles.

The technology of the next few decades could possibly allow us to explore with robotic probes the closest stars outside our Solar System, and maybe even observe some of the recently discovered planets circling these stars. This book looks at the reasons for exploring our stellar neighbors and at the technologies we are developing to build space probes that can traverse the enormous distances between the stars. In order to reach the nearest stars, we must first develop a propulsion technology that would take our robotic probes there in a reasonable time. Such propulsion technology has radically different requirements from conventional chemical rockets, because of the enormous distances that must be crossed. Surprisingly, many propulsion schemes for interstellar travel have been suggested and await only practical engineering solutions and the political will to make them a reality. This is a result of the tremendous advances in astrophysics that have been made in recent decades and the perseverance and imagination of tenacious theoretical physicists. This book explores these different propulsion schemes – all based on current physics – and the challenges they present to physicists, engineers, and space exploration entrepreneurs. This book will be helpful to anyone who really wants to understand the principles behind and likely future course of interstellar travel and who wants to recognizes the distinctions between pure fantasy (such as Star Trek’s ‘warp drive’) and methods that are grounded in real physics and offer practical technological solutions for exploring the stars in the decades to come.

Annotation This practical book gives young professionals all the information they need to know to get started in the space business. It takes you step-by-step through processes for systems engineering and acquisition, design and development, cost analysis, and program planning and analysis. You'll find the systems engineering and design process that applies to all space transportation systems, then the overall system architecture considerations that also apply to all space transportation systems. There is also detailed coverage of space launch vehicles by class, including the current space shuttle, other manned reusable systems, expendable systems, and future systems. A companion CD-ROM contains the Operations Simulation and Analysis Modeling System software.
