Book Description
Modern airborne weapons systems face increasingly stringent demands for improved performance and lower cost of ownership. The key to attaining the first of these demands is increased sub-systems integration, which leverages improved component performance to make even greater improvements in overall weapons system capability. Research is essential to gaining a fundamental understanding of the behavior and control of these highly integrated systems. Progress towards meeting the affordability demands for these systems is also being closely scrutinized. Recognition and control of ownership costs has become increasingly difficult in the face of increasing systems complexity. It may be possible to reduce the amount of physical engine test required in a typical gas turbine engine development program through the use of simulation and modeling techniques in a virtual engine test cell. However, in order to establish the credibility of a simulation and modeling approach to virtual engine test, carefully documented verification and validation (V & V) activities must be undertaken during model development.

Riveted Lap Joints in Aircraft Fuselage

Riveted Lap Joints in Aircraft Fuselage PDF Author: Andrzej Skorupa
Publisher: Springer Science & Business Media
ISBN: 9400742827
Category : Technology & Engineering
Languages : en
Pages : 346

Book Description
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.

The Aerodynamics of Heavy Vehicles III

The Aerodynamics of Heavy Vehicles III PDF Author: Andreas Dillmann
Publisher: Springer
ISBN: 3319201220
Category : Technology & Engineering
Languages : en
Pages : 416

Book Description
This volume contains papers presented at the International conference “The Aerodynamics of Heavy Vehicles III: Trucks, Buses and Trains” held in Potsdam, Germany, September 12-17, 2010 by Engineering Conferences International (ECI). Leading scientists and engineers from industry, universities and research laboratories, including truck and high-speed train manufacturers and operators were brought together to discuss computer simulation and experimental techniques to be applied for the design of more efficient trucks, buses and high-speed trains in the future. This conference was the third in the series after Monterey-Pacific Groove in 2002 and Lake Tahoe in 2007.The presentations address different aspects of train aerodynamics (cross wind effects, underbody flow, tunnel aerodynamics and aeroacoustics, experimental techniques), truck aerodynamics (drag reduction, flow control, experimental and computational techniques) as well as computational fluid dynamics and bluff body, wake and jet flows.

The DelFly

The DelFly PDF Author: G.C.H.E. de Croon
Publisher: Springer
ISBN: 9401792089
Category : Technology & Engineering
Languages : en
Pages : 221

Book Description
This book introduces the topics most relevant to autonomously flying flapping wing robots: flapping-wing design, aerodynamics, and artificial intelligence. Readers can explore these topics in the context of the "Delfly", a flapping wing robot designed at Delft University in The Netherlands. How are tiny fruit flies able to lift their weight, avoid obstacles and predators, and find food or shelter? The first step in emulating this is the creation of a micro flapping wing robot that flies by itself. The challenges are considerable: the design and aerodynamics of flapping wings are still active areas of scientific research, whilst artificial intelligence is subject to extreme limitations deriving from the few sensors and minimal processing onboard. This book conveys the essential insights that lie behind success such as the DelFly Micro and the DelFly Explorer. The DelFly Micro, with its 3.07 grams and 10 cm wing span, is still the smallest flapping wing MAV in the world carrying a camera, whilst the DelFly Explorer is the world's first flapping wing MAV that is able to fly completely autonomously in unknown environments. The DelFly project started in 2005 and ever since has served as inspiration, not only to many scientific flapping wing studies, but also the design of flapping wing toys. The combination of introductions to relevant fields, practical insights and scientific experiments from the DelFly project make this book a must-read for all flapping wing enthusiasts, be they students, researchers, or engineers.

Aerospace power in the twenty-first century a basic primer PDF Author: Clayton K. S. Chun
Publisher: DIANE Publishing
ISBN: 1428990291
Category : Air power
Languages : en
Pages : 351

Book Description
Dr. Chun's Aerospace Power in the Twenty-First Century: A Basic Primer is a great start towards understanding the importance of aerospace power and its ability to conduct modern warfare. Aerospace power is continually changing because of new technology, threats, and air and space theories. However, many basic principles about aerospace power have stood the test of time and warfare. This book provides the reader with many of these time-tested ideas for consideration and reflection. Although Aerospace Power in the Twenty-First Century was written for future officers, individuals desiring a broad overview of aerospace power are invited to read, share, and discuss many of the ideas and thoughts presented here. Officers from other services will find that this introduction to air and space forces will give them a good grasp of aerospace power. More experienced aerospace leaders can use this book to revisit many of the issues that have affected air and space forces in the past and that might affect them in the future. Air Force officers will discover that Aerospace Power in the Twenty-First Century is a very timely and reflective resource for their professional libraries.
