Among various mechanical devices built to produce power for industrial and societal needs, gas turbines offer a number of significant advantages. The sliding components in reciprocating engines cause considerable vibrations. Hydroelectric power from turbines using water is a great resource, but potential sites are limited. Steam power plants require expensive steam generating equipment of large bulk, and installation may stretch over lengthy time periods. In contrast, gas turbines operate smoothly with low vibrations, are compact in size, can be started rapidly from rest and may be installed fairly quickly. Gas turbines offer even greater benefits in the aviation arena. Turbojet and multi-rotor turbofan engines have no competition for powering larger aircrafts at faster speeds. Applications in other fields abound. An outstanding example is the aeroderivative gas turbines on offshore oil platforms, where their lighter weight, smaller footprint and ability to burn many different types of fuel make it a clear choice. This book is written to meet the needs of students in engineering colleges and practicing engineers. The material has been specifically tailored for college undergraduate and graduate level design engineering of rotating machine courses. In keeping with its mostly introductory nature, the primary focus is on thermodynamic cycle design and practical mechanical design features. Where possible, electronic spreadsheet type of calculations is used in example problems to calculate flow characteristics and related cycle design parameters. The book focuses on: Fuel consumption, power output and exhaust gas emissions State-of-the-art in the thermal and fluid flow technologies for design of single and multi-rotor gas turbines Methods to enhance performance through creative component designs Analysis of complex problems ranging from compressor stall to optimizing operation from partial to full load.

21st Century Kinematics focuses on algebraic problems in the analysis and synthesis of mechanisms and robots, compliant mechanisms, cable-driven systems and protein kinematics. The specialist contributors provide the background for a series of presentations at the 2012 NSF Workshop. The text shows how the analysis and design of innovative mechanical systems yield increasingly complex systems of polynomials, characteristic of those systems. In doing so, it takes advantage of increasingly sophisticated computational tools developed for numerical algebraic geometry and demonstrates the now routine derivation of polynomial systems dwarfing the landmark problems of even the recent past. The 21st Century Kinematics workshop echoes the NSF-supported 1963 Yale Mechanisms Teachers Conference that taught a generation of university educators the fundamental principles of kinematic theory. As such these proceedings will provide admirable supporting theory for a graduate course in modern kinematics and should be of considerable interest to researchers in mechanical design, robotics or protein kinematics or who have a broader interest in algebraic geometry and its applications.

During the last decade, rapid advances have been made in the area of flow analysis in the components of gas turbine engines. Improving the design methods of turbomachine blade rows and under standing of the flow phenomena through them, has become one of the major research topics for aE'rodynamists. This increase of research efforts is due to the need of reducing the weight and fuel consumption of turbojet engines for the same thrust levels. One way of achieving this is to design more efficient components working at high local velocities. Design efforts can lead to desired results only if the details of flow through the blade rows are understood. It is also known that for aircraft propulsion systems development, time and cost can be reduced significantly if the perf ormance can be predicted with conf idence and enough precision.

The book explores the geometric and kinematic design of the various types of gears most commonly used in practical applications, also considering the problems concerning their cutting processes. The cylindrical spur and helical gears are first considered, determining their main geometric quantities in the light of interference and undercut problems, as well as the related kinematic parameters. Particular attention is paid to the profile shift of these types of gears either generated by rack-type cutter or by pinion-rack cutter. Among other things, profile-shifted toothing allows to obtain teeth shapes capable of greater strength and more balanced specific sliding, as well as to reduce the number of teeth below the minimum one to avoid the operating interference or undercut. These very important aspects of geometric-kinematic design of cylindrical spur and helical gears are then generalized and extended to the other examined types of gears most commonly used in practical applications, such as: straight bevel gears; crossed helical gears; worm gears; spiral bevel and hypoid gears. Finally, ordinary gear trains, planetary gear trains and face gear drives are discussed. Includes fully-developed exercises to draw the reader's attention to the problems that are of interest to the designer, as well as to clarify the calculation procedure Topics are addressed from a theoretical standpoint, but in such a way as not to lose sight of the physical phenomena that characterize the various types of gears which are examined The analytical and numerical solutions are formulated so as to be of interest not only to academics, but also to designers who deal with actual engineering problems concerning the gears

This book aims to develop systematic design methodologies to model-based nonlinear control of aeroengines, focusing on (1) modelling of aeroengine systems-both component-level and identification-based models will be extensively studied and compared; and (2) advanced nonlinear control designs-set-point control, transient control and limit-protection control approaches will all be investigated. The model-based design has been one of the pivotal technologies to advanced control and health management of propulsion systems. It can fulfil advanced designs such as fault-tolerant control, engine modes control and direct thrust control. As a consequence, model-based design has become an important research area in the field of aeroengines due to its theoretical interests and engineering significance. One of the central issues in model-based controls is the tackling of nonlinearities. There are publications concerning with either nonlinear modelling or nonlinear controls; yet, they are scattered throughout the literature. It is time to provide a comprehensive summary of model-based nonlinear controls. Consequently, a series of important results are obtained and a systematic design methodology is developed which provides consistently enhanced performance over a large flight/operational envelope, and it is thus expected to provide useful guidance to practical engineering in aeroengine industry and research.
