Book Synopsis Aircraft Drag Reduction Through Extended Formation Flight by : Simeon Andrew Ning
Download or read book Aircraft Drag Reduction Through Extended Formation Flight written by Simeon Andrew Ning and published by Stanford University. This book was released on 2011 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Formation flight has the potential to significantly reduce the fuel consumption of long range flights, even with existing aircraft. This research explores a safer approach to formation flying of transport aircraft, which we term extended formation flight. Extended formations take advantage of the persistence of cruise wakes and extend the streamwise separation between the aircraft by at least five wingspans. Classical aerodynamic theory suggests that the total induced drag of the formation should not change as the streamwise separation is increased, but the large separation distances of extended formation flight violate the simple assumptions of these theorems. At large distances, considerations such as wake rollup, atmospheric effects on circulation decay, and vortex motion become important to consider. We first examine the wake rollup process in the context of extended formations and develop an appropriate physics-based model. Using this model, this dissertation addresses three aspects of formation flight: longitudinally extended formations, compressibility effects, and formations of heterogeneous aircraft. Uncertainty analysis is used to investigate the induced drag savings of extended formations in the presence of variation in atmospheric properties, limitations of positioning accuracy, and uncertainty in model parameters. Next, the methodology is integrated with an Euler solver to assess the impact of compressibility while flying in formation. Finally, we examine the important considerations for optimally arranging formations of non-identical aircraft.

The objective of the book is to provide the reader with comprehensive coverage on the Robot Operating System (ROS), which is currently considered to be the primary development framework for robotics applications, and the latest trends and contributing systems. The content is divided into six parts. Pat I presents for the first time the emerging ROS 2.0 framework, while Part II focuses on multi-robot systems, namely on SLAM and Swarm coordination. Part III provides two chapters on autonomous systems, namely self-driving cars and unmanned aerial systems. In turn, Part IV addresses the contributions of simulation frameworks for ROS. In Part V, two chapters explore robotic manipulators and legged robots. Finally, Part VI presents emerging topics in monocular SLAM and a chapter on fault tolerance systems for ROS. Given its scope, the book will offer a valuable companion for ROS users and developers, helping them deepen their knowledge of ROS capabilities and features.
Book Synopsis Bio-Inspired Innovation and National Security by : National Defense University
Download or read book Bio-Inspired Innovation and National Security written by National Defense University and published by NDU Press. This book was released on 2010-10 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the vital importance of the emerging area of biotechnology and its role in defense planning and policymaking, no definitive book has been written on the topic for the defense policymaker, the military student, and the private-sector bioscientist interested in the "emerging opportunities market" of national security. This edited volume is intended to help close this gap and provide the necessary backdrop for thinking strategically about biology in defense planning and policymaking. This volume is about applications of the biological sciences, here called "biologically inspired innovations," to the military. Rather than treating biology as a series of threats to be dealt with, such innovations generally approach the biological sciences as a set of opportunities for the military to gain strategic advantage over adversaries. These opportunities range from looking at everything from genes to brains, from enhancing human performance to creating renewable energy, from sensing the environment around us to harnessing its power.

Book Synopsis Flying beyond the stall by : Douglas A. Joyce
Download or read book Flying beyond the stall written by Douglas A. Joyce and published by . This book was released on 2014 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: The X-31 Enhanced Fighter Maneuverability Demonstrator was unique among experimental aircraft. A joint effort of the United States and Germany, the X-31 was the only X-plane to be designed, manufactured, and flight tested as an international collaboration. It was also the only X-plane to support two separate test programs conducted years apart, one administered largely by NASA and the other by the U.S. Navy, as well as the first X-plane ever to perform at the Paris Air Show. Flying Beyond the Stall begins by describing the government agencies and private-sector industries involved in the X-31 program, the genesis of the supermaneuverability concept and its initial design breakthroughs, design and fabrication of two test airframes, preparation for the X-31's first flight, and the first flights of Ship #1 and Ship #2. Subsequent chapters discuss envelope expansion, handling qualities (especially at high angles of attack), and flight with vectored thrust. The book then turns to the program's move to NASA's Dryden Flight Research Center and actual flight test data. Additional tasking, such as helmet-mounted display evaluations, handling quality studies, aerodynamic parameter estimation, and a "tailless" study are also discussed.The book describes how, in the aftermath of a disastrous accident with Ship #1 in 1995, Ship #2 was prepared for its outstanding participation in the Paris Air Show. The aircraft was then shipped back to Edwards AFB and put into storage until the late 1990s, when it was refurbished for participation in the U. S. Navy's VECTOR program. The book ends with a comprehensive discussion of lessons learned and includes an Appendix containing detailed information.

Book excerpt: From the Introduction: This volume is designed as an overview of the many applications of biology to the military and national security writ large (with the exception of bioweapons and biomedicine). Policy issues are covered, and original research is presented. The diversity of the authors' backgrounds reflects the breadth of applications and opportunities of biology to modern problems. The read should walk away enlightened as to the many possible ways in which biology is influencing and will continue to influence national security. Authors were asked to provede foresight on trends and indicators in their areas of interest (but not forecasts, which would describe a single future state) in order to better understand their implications for the next 20 years or so.
Book Synopsis Sierra Hotel : flying Air Force fighters in the decade after Vietnam by :
Download or read book Sierra Hotel : flying Air Force fighters in the decade after Vietnam written by and published by DIANE Publishing. This book was released on 2001 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: In February 1999, only a few weeks before the U.S. Air Force spearheaded NATO's Allied Force air campaign against Serbia, Col. C.R. Anderegg, USAF (Ret.), visited the commander of the U.S. Air Forces in Europe. Colonel Anderegg had known Gen. John Jumper since they had served together as jet forward air controllers in Southeast Asia nearly thirty years earlier. From the vantage point of 1999, they looked back to the day in February 1970, when they first controlled a laser-guided bomb strike. In this book Anderegg takes us from "glimmers of hope" like that one through other major improvements in the Air Force that came between the Vietnam War and the Gulf War. Always central in Anderegg's account of those changes are the people who made them. This is a very personal book by an officer who participated in the transformation he describes so vividly. Much of his story revolves around the Fighter Weapons School at Nellis Air Force Base (AFB), Nevada, where he served two tours as an instructor pilot specializing in guided munitions.

Book Synopsis Command Of The Air by : General Giulio Douhet
Download or read book Command Of The Air written by General Giulio Douhet and published by Pickle Partners Publishing. This book was released on 2014-08-15 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the pantheon of air power spokesmen, Giulio Douhet holds center stage. His writings, more often cited than perhaps actually read, appear as excerpts and aphorisms in the writings of numerous other air power spokesmen, advocates-and critics. Though a highly controversial figure, the very controversy that surrounds him offers to us a testimonial of the value and depth of his work, and the need for airmen today to become familiar with his thought. The progressive development of air power to the point where, today, it is more correct to refer to aerospace power has not outdated the notions of Douhet in the slightest In fact, in many ways, the kinds of technological capabilities that we enjoy as a global air power provider attest to the breadth of his vision. Douhet, together with Hugh “Boom” Trenchard of Great Britain and William “Billy” Mitchell of the United States, is justly recognized as one of the three great spokesmen of the early air power era. This reprint is offered in the spirit of continuing the dialogue that Douhet himself so perceptively began with the first edition of this book, published in 1921. Readers may well find much that they disagree with in this book, but also much that is of enduring value. The vital necessity of Douhet’s central vision-that command of the air is all important in modern warfare-has been proven throughout the history of wars in this century, from the fighting over the Somme to the air war over Kuwait and Iraq.
