Book Description
The adaptation of ZONA unified hypersonic/supersonic method ZONA7U and its integration/development into a ZONA aerothermoelastic software system for transatmospheric vehicle (TAV)/thermal protection system (TPS) design/analysis was proven a successful tool through feasibility study with cases of a CKEM body, blunt cones, and a modeled X-34 wing body. Preceding the feasibility study, substantial effort was directed toward further development of a new code, ZSTREAM, and using it and ZABRO to replace the outdated modules in SHVD, thus to couple them with SHABP for aerothermoelastic applications. In the feasibility study, the cases are well validated with FD solutions. Next, computed heat rates by applying ZONA aerothermoelastic software to X-34 through two assigned hypersonic trajectories were shown and found to agree with those using MINIVER. A potential TPS design procedure was established using the obtained heat rates as an input to MINIVER, resulting in a minimum weight TPS per hot-wall consideration. With FEM/TRIM modules, ASTROS* yields the trim solution and stress distribution for a flexible X-34 at a typical trajectory joint, demonstrating the multifunctionality in MDO for the aerothermoelastic software.

Book Description
This book introduces the fundamental concepts of inverse heat transfer problems. It presents in detail the basic steps of four techniques of inverse heat transfer protocol, as a parameter estimation approach and as a function estimation approach. These techniques are then applied to the solution of the problems of practical engineering interest involving conduction, convection, and radiation. The text also introduces a formulation based on generalized coordinates for the solution of inverse heat conduction problems in two-dimensional regions.

Book Description
Drawn from early volumes of Aerospace America and its antecedents, this book rescues the insights, concerns, and dreams of dozens of structural engineers for the next generation of aerospace scientists and engineers. Written by eminent individuals in structures, this book provides accessible source material for university-level design courses in aerospace engineering. The first paper in Structures Technology deals with new structures for future aerospace systems and provides a contrast between our current thinking and past technology plans. Succeeding papers are historical reports covering materials and structures, general structures technology, aircraft structures, space structures, and structural dynamics technology. You will also find sections covering structural configurations, thermal protection systems, subsonic aircraft, supersonic and hypersonic vehicles and structures for space systems.

Book Description
This book is devoted to studies of unsteady heat and mass exchange processes taking into account thermochemical destruction of thermal protective materials, research of transpiration cooling systems, thermal protection of composite materials exposed to low-energy disturbances, as well as the numerical solution of heat and mass transfer of the exchange. It proposes several mathematical models of passive and active thermal protection systems with regard to factors such as surface ablation, surface roughness, phase transition of a liquid in porous materials, rotation of the body around its longitudinal axis, and exposure to low-energy disturbances. The author studies the possibilities to control thermochemical destruction and heat mass exchange processes in transpiration cooling systems exposed to low-energy disturbances. The numerical analysis of the heat and mass exchange process in carbon plastics under repeated impulse action is also presented. The numerical solutions of problems are compared with the known experimental data. The book is intended for specialists in the field of thermal protection and heat mass exchange, as well as graduate and undergraduates in physics and mathematics.

Book Description
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.

Book Description
This report summarizes the work entitled 'Advances in Hypersonic Vehicle Synthesis with Application to Studies of Advanced Thermal Protection Systems.' The effort was in two areas: (1) development of advanced methods of trajectory and propulsion system optimization; and (2) development of advanced methods of structural weight estimation. The majority of the effort was spent in the trajectory area. Ardema, Mark D. Unspecified Center...
