The volume provides an exhaustive catalog of common standard day corrections for gas turbine gas path parameters, explores their history, and, most importantly, provides a mathematical framework for the derivation of these important normalization factors. Although use of these corrections is common practice within industry, government, and academia, their genesis, and, in particular, how they can be derived from simple principles, is not general knowledge among many of those who use them on a regular basis. This book elucidates calculation of these important coefficients. Standing as a one-stop source on derivations and a methodology for additional parameter correction refinements, Gas Turbine Parameter Corrections, is ideal as a desk reference for practitioners and researchers, as well as supplemental instruction for university courses on gas turbine performance, control, and DPHM (diagnostics, prognostics and health management).

This book provides a comprehensive study of multi-stage and multi-time scale design of feedback controllers for linear dynamic systems. It examines different types of controllers as can be designed for different parts of the system (subsystems) using corresponding feedback gains obtained by performing calculations (design) only with subsystem (reduced-order) matrices.The advantages of the multi-stage/multi-time scale design are presented and conditions for implementation of these controllers are established. Complete derivations and corresponding design techniques are presented for two-stage/two-time-scale, three-stage/three-time scale, and four-stage/four-time-scale systems. The techniques developed have potential applications to a large number of real physical systems. The design techniques are demonstrated on examples of mathematical models of fuel cells, especially the proton exchange membrane fuel cell.

STRUCTURAL DYNAMICS OF TURBO-MACHINES presents a detailed and comprehensive treatment of structural vibration evaluation of turbo-machines. Starting with fundamentals of the theory of vibration as related to various aspects of rotating machines, the dynamic analysis procedures of a broad spectrum of turbo-machines is covered. An in-depth procedure for analyzing the torsional and flexural oscillations of the components and of the rotor-bearing system is presented. The latest trends in design and analysis are presented, chief among them: * Blade and coupled disk-blade modes of vibration * Dynamic instability, non-linear phenomena, their causes and consequences * Methods to control rotor-to-stator clearance and improving operating efficiency * Experimental techniques and analytical correlation with variables ranging from blade flutter to bearing orbital trajectory * Fatigue failures arising from thermal ratcheting and cyclical operating loads * Material characteristics and requirements Growth in machine operating parameters and user expectations require exacting consideration of dynamic characteristics. State-of-the-art technology is required to understand blade dynamics and rotating system vibrations. Vibration measurement is an important tool in diagnostics. This book develops methods to understand vibrations and correct major causes of related problems. Emphasis is placed on practical modeling methods, interpreting results and obtaining realistic solutions. Analysis as a problem solving tool is the focus.

The ever-increasing demands placed on combustion engines are just as great when it comes to this centerpiece-the piston. Achieving less weight or friction, or even greater wear resistance, requires in-depth knowledge of the processes taking place inside the engine, suitable materials, and appropriate design and manufacturing processes for pistons, including the necessary testing measures. It is no longer possible for professionals in automotive engineering to manage without specific expertise of this kind, whether they work in the field of design, development, testing, or maintenance. This technical book answers these questions in detail and in a very clear and comprehensible way. In this second, revised edition, every chapter has been revised and expanded. The chapter on "Engine testing", for example, now include extensive results in the area of friction power loss measurement and lube oil consumption measurement.
This book discusses electric power transmission and related policy issues. Transmission is a prominent federal issue because of a perceived need to improve reliability and reduce costs, transmission's role in meeting national energy goals (such as increased use of renewable electricity), and the potential efficiency advantages of "smart grid" modernisation. Proposals before the 111th Congress for changing federal transmission law and regulations to meet these and other objectives include the Clean Renewable Energy and Economic Development Act and the majority staff transmission siting draft of the Senate Energy and Natural Resources Committee. Transmission development and regulation are complex and sometimes contentious policy areas and this book reviews transmission planning and permitting, financing and cost allocation, system modernisation and the smart grid and transmission system reliability.
Thermodynamics is a subject that all engineering students have to face and that most of them treat with great respect. This makes it all the more important to offer a good and easy-to-understand approach to the laws of energy conversion. This is what this textbook is intended to do: It covers the basics of classical technical thermodynamics as they are typically taught at universities: The first and second law of thermodynamics as well as equations of state are explained for idealized and real fluids which are subject to a phase change. Thermodynamic mixtures, e.g. humid air, are treated as well as chemical reactions. Components and thermodynamic cycle that convert energy are presented. The book attaches great importance to drawings and illustrations, which should make it easier to comprehend complex matter. Technical applications and apparatus are presented and explained. Numerous exercises and examples conclude the book and contribute to a better understanding of the theory.
America's First Rocket Company is the story of Reaction Motors, Inc. (RMI), the first U.S. liquid-propellant rocket company. Founded in December 1941 following the bombing of Pearl Harbor, with the single-minded goal of developing the liquid-propellant rocket for the war effort, RMI was an ambitious undertaking at a time when rocket propulsion technology was in its infancy. RMI went on to accomplish some of the most significant technological breakthroughs in American aerospace history, paving the way to manned flights far beyond the speed of sound, the beginnings of manned flight into space, and development of the critically important Vernier motors for the Surveyor spacecraft that became the first U.S. soft-landing craft on the surface of the moon. America's First Rocket Company helps to fittingly commemorate the 75th anniversary of the founding of this truly pioneering American rocket company.
