This book was released on 1997 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chordwise pressure distributions were obtained in-flight on the upper and lower surfaces of the F-16XL ship 2 aircraft wing between Mach 1.4 and Mach 2.0. This experiment was conducted to determine the location of shock waves which could compromise or invalidate a follow-on test of a large chord laminar flow control suction panel. On the upper surface, the canopy closure shock crossed an area which would be covered by a proposed laminar flow suction panel. At the laminar flow experiment design Mach number of 1.9, 91 percent of the suction panel area would be forward of the shock. At Mach 1.4, that value reduces to 65 percent. On the lower surface, a shock from the inlet diverter would impinge on the proposed suction panel leading edge. A chordwise plate mounted vertically to deflect shock waves, called a shock fence, was installed between the inlet diverter and the leading edge. This plate was effective in reducing the pressure gradients caused by the inlet shock system.

Download or read book Boundary-layer Transition Results from the F-16XL-2 Supersonic Laminar Flow Control Experiment written by Laurie A. Marshall and published by . This book was released on 1999 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: A variable-porosity suction glove has been flown on the F-16XL-2 aircraft to demonstrate the feasibility of this technology for the proposed High-Speed Civil Transport (HSCT). Boundary-layer transition data have been obtained on the titanium glove primarily at Mach 2.0 and altitudes of 53,000-55,000 ft. The objectives of this supersonic laminar flow control flight experiment have been to achieve 50- to 60-percent-chord laminar flow on a highly swept wing at supersonic speeds and to provide data to validate codes and suction design. The most successful laminar flow results have not been obtained at the glove design point (Mach 1.9 at an altitude of 50,000 ft). At Mach 2.0 and an altitude of 53,000 ft, which corresponds to a Reynolds number of 22.7 multiplied by 10[factor 6], optimum suction levels have allowed long runs of a minimum of 46-percent-chord laminar flow to be achieved. This paper discusses research variables that directly impact the ability to obtain laminar flow and techniques to correct for these variables.

Book Synopsis Aircraft Design Projects by : Lloyd R. Jenkinson
Download or read book Aircraft Design Projects written by Lloyd R. Jenkinson and published by Elsevier. This book was released on 2003-04-28 with total page 393 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written with students of aerospace or aeronautical engineering firmly in mind, this is a practical and wide-ranging book that draws together the various theoretical elements of aircraft design - structures, aerodynamics, propulsion, control and others - and guides the reader in applying them in practice. Based on a range of detailed real-life aircraft design projects, including military training, commercial and concept aircraft, the experienced UK and US based authors present engineering students with an essential toolkit and reference to support their own project work.All aircraft projects are unique and it is impossible to provide a template for the work involved in the design process. However, with the knowledge of the steps in the initial design process and of previous experience from similar projects, students will be freer to concentrate on the innovative and analytical aspects of their course project. The authors bring a unique combination of perspectives and experience to this text. It reflects both British and American academic practices in teaching aircraft design. Lloyd Jenkinson has taught aircraft design at both Loughborough and Southampton universities in the UK and Jim Marchman has taught both aircraft and spacecraft design at Virginia Tech in the US. * Demonstrates how basic aircraft design processes can be successfully applied in reality* Case studies allow both student and instructor to examine particular design challenges * Covers commercial and successful student design projects, and includes over 200 high quality illustrations

Book Synopsis A History of Suction-Type Laminar-Flow Control with Emphasis on Flight Research by : National Aeronautics and Space Administration
Download or read book A History of Suction-Type Laminar-Flow Control with Emphasis on Flight Research written by National Aeronautics and Space Administration and published by CreateSpace. This book was released on 2013-11 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laminar-flow control is an area of aeronautical research that has a long history at NASA's Langley Research Center, Dryden Flight Research Center, their predecessor organizations, and elsewhere. In this monograph, Albert L. Braslow, who spent much of his career at Langley working with this research, presents a history of that portion of laminar-flow technology known as active laminar-flow control, which employs suction of a small quantity of air through airplane surfaces. This important technique offers the potential for significant reduction in drag and, thereby, for large increases in range or reductions in fuel usage for aircraft. For transport aircraft, the reductions in fuel consumed as a result of laminar-flow control may equal 30 percent of present consumption. Given such potential, it is obvious that active laminar-flow control with suction is an important technology. In this study, the author covers the early history of the subject and brings the story all the way to the mid-1990s with an emphasis on flight research, much of which occurred at Dryden.

Book excerpt: A fascinating guided tour of the ways things work in a modern city “It's a rare person who won't find something of interest in The Works, whether it's an explanation of how a street-sweeper works or the view of what's down a manhole.” —New York Post Have you ever wondered how the water in your faucet gets there? Where your garbage goes? What the pipes under city streets do? How bananas from Ecuador get to your local market? Why radiators in apartment buildings clang? Using New York City as its point of reference, The Works takes readers down manholes and behind the scenes to explain exactly how an urban infrastructure operates. Deftly weaving text and graphics, author Kate Ascher explores the systems that manage water, traffic, sewage and garbage, subways, electricity, mail, and much more. Full of fascinating facts and anecdotes, The Works gives readers a unique glimpse at what lies behind and beneath urban life in the twenty-first century.

This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In "Aerodynamic Principles of Flight Vehicles" Argyris Panaras examines the fundamentals of vortices and shock waves, aerodynamic estimation of lift and drag, airfoil theory, boundary layer control, and high-speed, high-temperature flow. Individual chapters address vortices in aerodynamics, transonic and supersonic flows, transonic/supersonic aircraft configurations, and high-supersonic/hypersonic flows, beginning with definitions and historical data, and then describing present-day status and current research challenges. Emphasis is given to flow control, to the evolution of flight vehicle shapes as flight speed has increased, and to discoveries that enabled breakthrough developments in flight. The book: examines why various equations and technologies were developed, explains major contributors in areas such as vortices and aircraft wakes, drag buildup, sonic boom, and shock wave-boundary layer interactions, among others, and helps readers apply concepts from the material to their own projects. Archival and encyclopedic, "Aerodynamic Principles of Flight Vehicles" is a superb reference for aeronautical students and professionals alike. Although most beneficial to readers with a working knowledge of aerodynamics, it is accessible to anyone with an introductory understanding of the field.

Book excerpt: From the late 1960s until the end of the Cold War, the United States Air Force acquired and flew Russian-made MiG jets, culminating in a secret squadron dedicated to exposing American fighter pilots to enemy technology and tactics. Red Eagles tells the story of this squadron from the first tests of MiGs following the Vietnam War when the USAF had been woefully under-prepared in aerial combat. These initial flights would develop into the "black" or classified program known internally as Constant Peg. At a secret air base in Nevada, ace American fighter pilots were presented with a range of differnet MiG jets with a simple remit: to expose "the threat" to as many of their brethern as possible. Maintaining and flying these "assets" without without spare parts or manuals was an almost impossible task, putting those flying the MiGs in mortal danger on every flight. Despite these challenges, in all more than 5,900 American aircrews would train against America's secret MiGs, giving them the eskills they needed to face the enemy in real combat situations. For the first time, this book tells the story of Constant Peg and the 4477th Red Eagles Squadron in the words of the men who made it possible.

Available in PDF, EPUB and Kindle. Book excerpt: Foreword by Dr. Roger D. Launius, Former NASA Chief Historian For the past 75 years, the U.S. government has invested significant time and money into advanced aerospace research, as evidenced by its many experimental X-plane aircraft and rockets. NASA's X-Planes asks a simple question: What have we gained from it all? To answer this question, the authors provide a comprehensive overview of the X-plane’s long history, from the 1946 X-1 to the modern X-60. The chapters describe not just the technological evolution of these models, but also the wider story of politics, federal budgets, and inter-agency rivalries surrounding them. The book is organized into two sections, with the first covering the operational X-planes that symbolized the Cold War struggle between the U.S. and the U.S.S.R, and the second section surveying post-Cold War aircraft and spacecraft. Featuring dozens of original illustrations of X-plane cross-sections, in-flight profiles, close-ups, and more, this book will educate general readers and specialists alike.
Book Synopsis The Aerodynamic Design of Aircraft by : Dietrich Küchemann
Download or read book The Aerodynamic Design of Aircraft written by Dietrich Küchemann and published by AIAA Education. This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dietrich Kuchemann's The Aerodynamic Design of Aircraft is as relevant and as forward looking today as it was when it was first published in 1978. It comprises the philosophy and life's work of a unique and visionary intellect. Based upon material taught in a course at Imperial College London, the insight and intuition conveyed by this text are timeless. With its republication, Kuchemann's influence will extend to the next generation of aerospace industry students and practitioners and the vehicles they will produce. Kuchemann establishes three classes of aircraft based on the character of flow involved. Each class is suitable for a distinct cruise speed regime: classical and swept aircraft for subsonic and transonic cruise, slender-wing aircraft for supersonic cruise, and wave-rider aircraft for hypersonic cruise. Unlike most engineering texts, which focus on a set of tools, Kuchemann's approach is to focus on the problem and its solution - what kind of flow is best for a given class of aircraft and how to achieve it.With this approach, Kuchemann fully embraces the true inverse nature of design; rather than answer what flow given the shape, he strives to answer what flow given the purpose and then what shape given the flow.

Book Synopsis Riveted Lap Joints in Aircraft Fuselage by : Andrzej Skorupa
Download or read book Riveted Lap Joints in Aircraft Fuselage written by Andrzej Skorupa and published by Springer Science & Business Media. This book was released on 2012-06-23 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fatigue of the pressurized fuselages of transport aircraft is a significant problem all builders and users of aircraft have to cope with for reasons associated with assuring a sufficient lifetime and safety, and formulating adequate inspection procedures. These aspects are all addressed in various formal protocols for creating and maintaining airworthiness, including damage tolerance considerations. In most transport aircraft, fatigue occurs in lap joints, sometimes leading to circumstances that threaten safety in critical ways. The problem of fatigue of lap joints has been considerably enlarged by the goal of extending aircraft lifetimes. Fatigue of riveted lap joints between aluminium alloy sheets, typical of the pressurized aircraft fuselage, is the major topic of the present book. The richly illustrated and well-structured chapters treat subjects such as: structural design solutions and loading conditions for fuselage skin joints; relevance of laboratory test results for simple lap joint specimens to riveted joints in a real structure; effect of various production and design related variables on the riveted joint fatigue behaviour; analytical and experimental results on load transmission in mechanically fastened lap joints; theoretical and experimental analysis of secondary bending and its implications for riveted joint fatigue performance; nucleation and shape development of fatigue cracks in riveted longitudinal lap joints; overview of experimental investigations into the multi-site damage for full scale fuselage panels and riveted lap joint specimens; fatigue crack growth and fatigue life prediction methodology for riveted lap joints; residual strength predictions for riveted lap joints in a fuselage structure. The major issues of each chapter are recapitulated in the last section.
