From November 1990 through the end of February 1991, six carrier battle groups and two Marine air wings operated simultaneously in Southwest Asia in Operation Desert Shield/Storm (ODS/S). This massive deployment of Naval and marine aviation units put pressure on the Naval supply system to provide needed parts and supplies. Since certain items, such as jet engines, were particularly susceptible to breakdowns in the harsh desert environment in which the forces were operating, some divisions of the Naval aviation depots (NADEPs) were tasked to 'surge' selected repairs to provide the theater with spare end items and repair parts. One such division was the engine shop at NADEP North Island (San Diego, CA) which, among other tasks, was asked to surge its repair of T64 jet engines, the engines used in CH-53 helicopters. This Note focuses on the surge- related problems faced at North Island and on the management adaptations, particularly in materiel support, devised there in response. We visited North Island to discuss the production surge. To put North Island's experience in it proper context, we also visited the NADEPs at Cherry Point, NC, at Jacksonville, FLA, and at Norfolk, VA, as well as the Naval Air Systems Command in Washington, D.C., and the Aviation Supply Office in Philadelphia, PA.

"Making Jet Engines" presents a radical re-interpretation of the early history of the jet engine in Germany, Britain, and the United States and, through this, sets out a new account of the central features of twentieth-century invention. Hermione Giffard, without invoking foresight or conservative resistance to novelty, explores why individual firms decided not to develop jet engines, failed to do so, or succeeded, highlighting how each country pursued jet engines for reasons that reflected their particular war aims and industrial expertise. By beginning with production, the very structure of "Making Jet Engines "challenges the traditional way of telling stories of invention, for it focuses consecutively on production, development, inventive institutions, and, lastly, the celebrity of the jet engine s inventors, who she portrays as the employees that they were. By demonstrating the crucial importance of industry in the emergence of novelty, this is a game changing book for anyone interested in technological invention today. "

Combustion Chambers for Jet Propulsion Engines focuses on the design of combustion chambers for turbo-jet and ramjet engines, including reheat systems. This compilation, which is a training manual for the combustion chamber course held in the Moscow Aeronautical Institute, provides a general presentation of the basic elements of the process of operation, characteristics, and design of combustion chambers. This manual is divided into two parts. Part One discusses the elements of chemical kinetics and the theory of combustion of a homogeneous mixture in gas streams. The second part is devoted to the thermodynamics of the combustion chamber; aerodynamic and thermal losses; construction of the combustion chamber; and description of the operating process. The problem concerning the effect of losses in combustion chambers on the characteristics of jet propulsion engines is also elaborated in this text. This publication is valuable to aeronautical and combustion engineering students.

The escalating use of aircraft in the 21st century demands a thorough understanding of engine propulsion concepts, including the performance of aero engines. Among other critical activities,gas turbines play an extensive role in electric power generation, and marine propulsion for naval vessels and cargo ships. In the most exhaustive volume to date, this text examines the foundation of aircraft propulsion: aerodynamics interwoven with thermodynamics, heat transfer, and mechanical design. With a finely focused approach, the author devotes each chapter to a particular engine type, such as ramjet and pulsejet, turbojet, and turbofan. Supported by actual case studies, he illustrates engine performance under various operating conditions. Part I discusses the history, classifications, and performance of air breathing engines. Beginning with Leonardo and continuing on to the emergence of the jet age and beyond, this section chronicles inventions up through the 20th century. It then moves into a detailed discussion of different engine types, including pulsejet, ramjet, single- and multi-spool turbojet, and turbofan in both subsonic and supersonic applications. The author discusses Vertical Take Off and Landing aircraft, and provides a comprehensive examination of hypersonic scramjet and turbo ramjet engines. He also analyzes the different types of industrial gas turbines having single-and multi-spool with intercoolers, regenerators, and reheaters. Part II investigates the design of rotating compressors and turbines, and non-rotating components, intakes, combustion chambers, and nozzles for all modern jet propulsion and gas turbine engine systems, along with their performance. Every chapter concludes with illustrative examples followed by a problems section; for greater clarity, some provide a listing of important mathematical relations.

This landmark joint publication between the National Air and Space Museum and the American Institute of Aeronautics and Astronautics chronicles the evolution of the small gas turbine engine through its comprehensive study of a major aerospace industry. Drawing on in-depth interviews with pioneers, current project engineers, and company managers, engineering papers published by the manufacturers, and the tremendous document and artifact collections at the National Air and Space Museum, the book captures and memorializes small engine development from its earliest stage. Leyes and Fleming leap back nearly 50 years for a first look at small gas turbine engine development and the seven major corporations that dared to produce, market, and distribute the products that contributed to major improvements and uses of a wide spectrum of aircraft. In non-technical language, the book illustrates the broad-reaching influence of small turbinesfrom commercial and executive aircraft to helicopters and missiles deployed in recent military engagements. Detailed corporate histories and photographs paint a clear historical picture of turbine development up to the present. See for yourself why The History of North American Small Gas Turbine Aircraft Engines is the most definitive reference book in its field. The publication of The History of North American Small Gas Turbine Aircraft Engines represents an important milestone for the National Air and Space Museum (NASM) and the American Institute of Aeronautics and Astronautics (AIAA). For the first time, there is an authoritative study of small gas turbine engines, arguably one of the most significant spheres of aeronautical technology in the second half o

Uncertainty Quantification In Computational Fluid Dynamics And Aircraft Engines

This book introduces novel design techniques developed to increase the safety of aircraft engines. The authors demonstrate how the application of uncertainty methods can overcome problems in the accurate prediction of engine lift, caused by manufacturing error. This in turn ameliorates the difficulty of achieving required safety margins imposed by limits in current design and manufacturing methods. This text shows that even state-of-the-art computational fluid dynamics (CFD) are not able to predict the same performance measured in experiments; CFD methods assume idealised geometries but ideal geometries do not exist, cannot be manufactured and their performance differs from real-world ones. By applying geometrical variations of a few microns, the agreement with experiments improves dramatically, but unfortunately the manufacturing errors in engines or in experiments are unknown. In order to overcome this limitation, uncertainty quantification considers the probability density functions of manufacturing errors. It is then possible to predict the overall variation of the jet engine performance using stochastic techniques. Uncertainty Quantification in Computational Fluid Dynamics and Aircraft Engines demonstrates that some geometries are not affected by manufacturing errors, meaning that it is possible to design safer engines. Instead of trying to improve the manufacturing accuracy, uncertainty quantification when applied to CFD is able to indicate an improved design direction. This book will be of interest to gas turbine manufacturers and designers as well as CFD practitioners, specialists and researchers. Graduate and final year undergraduate students may also find it of use.
