Blade aeroelasticity has long been regarded a distinctive and critical topic in aerospace and turbomachinery design. More recently, research activities have increased in the area of turbomachinery unsteady flows, and whilst the two topics have seemingly different applications, the many links between them give value to a complementary approach.Unsteady Flow and Aeroelasticity in Turbomachinery is the first high level reference to provide detailed, multi-disciplinary discussion of these related topics and their increasing importance in efforts to develop low-emission and low-noise engines and generators. Filling the need for a well-written book to bring together recent research developments, author Li He seeks to take a unified approach, with emphasis given to physical understanding of the various phenomena and relevant modeling issues before discussion of prediction methods and techniques.This unique resource is aimed at those facing unsteady aerodynamic or aeroelastic problems and aims to help engineers and researchers to overcome challenges in academic, industrial R&D and engine design environments.There are other books on unsteady aerodynamics, and aeroelasticity. The uniqueness is in writing a book focused on these topics in turbomachinery.

A memoir of a period at the aviation college, Embry Riddle, when its main campus was in Miami, Florida. It was at a time when airlines were replacing the slower propliners with jetliners and a disturbing number of airliners were crashing.

This book covers full syllabus of Aircraft & High Temperature Materials in B.E. (Aeronautical Engineering) and High Temperature Materials for M.E. (Materials Technology)

The articles in this volume present the state-of-the-art in noise prediction, modeling and measurement. The articles are partially based on class notes provided during the course 'Noise sources in turbulent shear flows', given at CISM on April 2011. The first part contains general concepts of aero acoustics, including vortex sound theory and acoustic analogies, in the second part particular emphasis is put into arguments of interest for engineers and relevant for aircraft design: jet noise, airfoil broadband noise, boundary layer noise (including interior noise and its control) and the concept of noise sources, their theoretical modeling and identification in turbulent lows. All these arguments are treated extensively with the inclusion of many practical examples and references to engineering applications.

Based on more than 10 years of teaching intermediate dynamics at the Air Force Institute of Technology, this book is suitable as a text for a graduate-level or advanced undergraduate-level course in 3-dimensional dynamics, or as a reference. The methods and techniques presented have been tested in the classroom, and have facilitated several research projects undertaken by the author. The basics of vector mathematics in three-dimensional space is introduced in the first chapter, and is facilitated by a vector notation that encourages a thorough understanding of kinematic and dynamic variables. Subsequent chapters cover particle kinematics, particle dynamics, rigid body kinematics, and rigid body dynamics using the framework of Newtonian mechanics. Energy and variational approaches, including Hamilton's Law of Varying Action, Hamilton's Principle, and Lagrange's Equation are introduced in Chapter 6. Each chapter includes solved problems, which demonstrate the concepts covered in the chapter, as well as additional problems that may be used as practice

Advanced Airship Technologies and Design Approaches identifies and outlines important airship design and practicability considerations and suggests a better design approach that will result in more successful development programs and lead to airships that are in synch with 21st century aviation practices and advanced military-commercial operating utility needs. Airships were very successful flying vehicles until the later 1930s when the rise of wing-borne aircraft gradually led to their demise. They continued in limited use until the 1960s as long-endurance naval patrol craft until they too were superseded by aircraft. A key advantage of the airship is that, once in flight, it requires dramatically less fuel than a conventional aircraft. In an age of rising fuel costs, the need for economical heavy lift transportation as well as specialized intelligence, surveillance, and reconnaissance (ISR) platforms is an opportune time to look again at lighter-than-air vehicle technology. An airship revival has proven difficult due to failed or canceled airship programs-proving corrosive to the perceived viability of the technology. The airship often struggles to be taken seriously, scoffed at as being ''just a blimp." If the present revival of interest in airships is to avoid a new generation of failures, or an inability to achieve promised results, it is essential to introduce an era of more prudent airship design, clear vision, and better management. Advanced Airship Technologies and Design Approaches offers a path forward. It is a must-read for all those with an interest in a successful future for airships.

The following NASA Contractor Report documents the indepth studies on select technologies that could support long-term aeronautical mobile communications operating concepts. This work was performed during the third and final phase of NASA's Technology Assessment for the FAA/EUROCONTROL Future Communications Study (FCS) under a multiyear NASA contract. It includes the associated findings of ITT Corporation and NASA Glenn Research Center to the Federal Aviation Administration (FAA) as of the end of May 2007. The activities documented in this report focus on three final technology candidates identified by the United States, and were completed before sufficient information about two additional technology candidates proposed by EUROCONTROL was made available. A separate report to be published by NASA (NASA/CR-2008-215144), entitled "Final Report on Technology Investigations for Provision of Future Aeronautical Communications" will include an assessment of all five final candidate technologies considered by the U.S. agencies (FAA and NASA) and EUROCONTROL. It will also provide an overview of the entire technology assessment process, including final recommendations. All three phases of this work were performed in compliance with the Terms of Reference for the Action Plan number 17 (AP-17) cooperative research agreement among EUROCONTROL, FAA, and NASA along with the general guidance of the FAA and EUROCONTROL available throughout this study.

Current developments in the field of air navigation services have been comprehensively described in this well-structured book. The division of air navigation services entered a new era of performance scheme that aims to meet requisite targets in four fundamental performance areas of safety, capacity, eco-friendliness and cost-efficiency. While it is highly expected that the targets are completely achieved, it is not recommended how; this being characteristic of performance based and goal oriented regulations. These key performance regions are interconnected by proportional and inversely proportional interrelations. For instance; if one aspires to expand sector capacity using the existing human resources (constant staff costs) but does not invest in technology (constant support cost) to accomplish higher cost-efficiency of service provision, the consequent overloaded system might unlock the Pandora's box of underlying safety issues. Since there is no scope of failure, we - the common, migrating and traveling public, airspace users, airport operators, air navigation services providers and the economy - will only benefit from this system; achieving goals of performance scheme in the process. However, the fundamental question which remains unanswered is "What is the winning strategy?" This book provides an understanding of noteworthy oddities of the elements of new business models of air navigation services provision as advancement of the latter became vital.

He provides the readers with a comprehensive review of the fundamental physics of free and forced unsteadiness, the terminology and basic equations of aerodynamics ranging from incompressible flow to hypersonics. The book also covers modern topics related to the developments made in recent years, especially in relation to wing flapping for propulsion. The book is written for graduate and senior year undergraduate students in aerodynamics and also serves as a reference for experienced researchers. Each chapter includes ample examples, questions, problems and relevant references. The treatment of these modern topics has been completely revised end expanded for the new edition. It now includes new numerical examples, a section on the ground effect, and state-space representation.

Computer simulations is a fundamental tool of the design process in many engineering disciplines including aerospace engineering. However, although high-fidelity numerical models are accurate, they can be computationally expensive with evaluation time for a single design as long as hours, days or even weeks. Simulation-driven design using conventional optimization techniques may be therefore prohibitive.This book explores the alternative: performing computationally efficient design using surrogate-based optimization, where the high-fidelity model is replaced by its computationally cheap but still reasonably accurate representation: a surrogate. The emphasis is on physics-based surrogates. Application-wise, the focus is on aerodynamics and the methods and techniques described in the book are demonstrated using aerodynamic shape optimization cases. Applications in other engineering fields are also demonstrated.State-of-the-art techniques and a depth of coverage never published before make this a unique and essential book for all researchers working in aerospace and other engineering areas and dealing with optimization, computationally expensive design problems, and simulation-driven design.

Based on components already in existence, this manual details a reference design for an interplanetary spacecraft that is simple, durable, fully reusable and comprised mostly of water. Using such an accessible material leads to a spacecraft architecture that is radically simpler, safer and cheaper than conventional capsule based designs. If developed, the potential affordability of the design will substantially open all of the inner solar system to human exploration. A spacecraft that is comprised mostly of water will be much more like a living cell or a terrarium than a conventional rocket and capsule design. It will use water for many purposes before it is superheated in electric engines for propulsion, purposes which include radiation shielding, heat management, basic life support, crew consumption and comfort. The authors coined the term "spacecoaches" to describe them, as an allusion to the Prairie Schooners of the Old West, which were simple, rugged, and could live off the land.

Advanced Control of Turbofan Engines describes the operational performance requirements of turbofan (commercial) engines from a controls systems perspective, covering industry-standard methods and research-edge advances. This book allows the reader to design controllers and produce realistic simulations using public-domain software like CMAPSS: Commercial Modular Aero-Propulsion System Simulation, whose versions are released to the public by NASA. The scope of the book is centered on the design of thrust controllers for both steady flight and transient maneuvers. Classical control theory is not dwelled on, but instead an introduction to general undergraduate control techniques is provided. Advanced Control of Turbofan Engines is ideal for graduate students doing research in aircraft engine control and non-aerospace oriented control engineers who need an introduction to the field.
