This book was released on 2018-08-20 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A low Reynolds number, high subsonic mach number flight regime is fairly uncommon in aeronautics. Most flight vehicles do not fly under these aerodynamic conditions. However, recently there have been a number of proposed aircraft applications (such as high altitude observation platforms and Mars aircraft) that require flight within this regime. One of the main obstacles to flight under these conditions is the ability to reliably generate sufficient thrust for the aircraft. For a conventional propulsion system, the operation and design of the propeller is the key aspect to its operation. Due to the difficulty in experimentally modeling the flight conditions in ground-based facilities, it has been proposed to conduct propeller experiments from a high altitude gliding platform (APEX). A preliminary design of a propeller experiment under the low Reynolds number, high mach number flight conditions has been devised. The details of the design are described as well as the potential data that will be collected.Colozza, Anthony J.Glenn Research CenterTHREE DIMENSIONAL MODELS; LOW REYNOLDS NUMBER; PROPELLERS; SUBSONIC SPEED; PERFORMANCE TESTS; EXPERIMENT DESIGN; FLIGHT CONDITIONS; GLIDING; HIGH ALTITUDE; MACH NUMBER; OBSERVATION AIRCRAFT; PROPULSION
Download or read book Optimizing Small Multi Rotor Unmanned Aircraft written by Stephen D. Prior and published by CRC Press. This book was released on 2018-09-18 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: This design guide was written to capture the author’s practical experience of designing, building and testing multi-rotor drone systems over the past decade. The lack of one single source of useful information meant that the past 10 years has been a steep learning curve, a lot of self-tuition and many trial and error tests. Lessons learnt the hard way are not always the best way to learn. This book will be useful for the amateur drone pilot who wants to build their own system from first principles, as well as the academic researcher investigating novel design concepts and future drone applications.

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
Download or read book Industrial System Engineering for Drones written by Neeraj Kumar Singh and published by Apress. This book was released on 2019-07-15 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Explore a complex mechanical system where electronics and mechanical engineers work together as a cross-functional team. Using a working example, this book is a practical “how to” guide to designing a drone system. As system design becomes more and more complicated, systematic, and organized, there is an increasingly large gap in how system design happens in the industry versus what is taught in academia. While the system design basics and fundamentals mostly remain the same, the process, flow, considerations, and tools applied in industry are far different than that in academia. Designing Drone Systems takes you through the entire flow from system conception to design to production, bridging the knowledge gap between academia and the industry as you build your own drone systems. What You’ll LearnGain a high level understanding of drone systems Design a drone systems and elaborating the various aspects and considerations of design Review the principles of the industrial system design process/flow, and the guidelines for drone systems Look at the challenges, limitations, best practices, and patterns of system design Who This Book Is For Primarily for beginning or aspiring system design experts, recent graduates, and system design engineers. Teachers, trainers, and system design mentors can also benefit from this content.

Download or read book Aircraft Conceptual Design Synthesis written by Denis Howe and published by . This book was released on 2000 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft Conceptual Design Synthesis means design by fitness-for-purpose. Design engineers can jump off from the point of given parameters and requirements – required performance, payloads and other factors. This is the first book for the aeronautical designer devoted to guiding the reader through this highly effective conceptual design synthesis process. This forms the procedure for the initial stage of the aircraft design process – the interpretation of a requirement into the preliminary layout. A logical design sequence is developed utilizing original modules to represent propulsion, lift, drag, mass, and performance. Aircraft Conceptual Design Synthesis includes a disk of spreadsheets that provides core data. Unlike existing approaches, the design synthesis method can be applied to novel aircraft concepts. CONTENTS INCLUDE The design process Aircraft configuration Flight regime and powerplant considerations Fuselage layout Configuration of the wing Basic lift, drag and mass representations Performance estimation Parametric analysis and optimisation Analysis of concept design “This is an important landmark book and in my view will become a standard by which others will be compared” – Dr E C P Ransom, Kingston University, UK

Download or read book The Praetorian STARShip the untold story of the Combat Talon written by and published by DIANE Publishing. This book was released on 2001 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jerry Thigpen's study on the history of the Combat Talon is the first effort to tell the story of this wonderfully capable machine. This weapons system has performed virtually every imaginable tactical event in the spectrum of conflict and by any measure is the most versatile C-130 derivative ever produced. First modified and sent to Southeast Asia (SEA) in 1966 to replace theater unconventional warfare (UW) assets that were limited in both lift capability and speed the Talon I quickly adapted to theater UW tasking including infiltration and resupply and psychological warfare operations into North Vietnam. After spending four years in SEA and maturing into a highly respected UW weapons system the Joint Chief of Staff (JCS) chose the Combat Talon to lead the night low-level raid on the North Vietnamese prison camp at Son Tay. Despite the outcome of the operation the Talon I cemented its reputation as the weapons system of choice for long-range clandestine operations. In the period following the Vietnam War United States Air Force (USAF) special operations gradually lost its political and financial support which was graphically demonstrated in the failed Desert One mission into Iran. Thanks to congressional supporters like Earl Hutto of Florida and Dan Daniel of Virginia funds for aircraft upgrades and military construction projects materialized to meet the ever-increasing threat to our nation. Under the leadership of such committed hard-driven officers as Brenci Uttaro Ferkes Meller and Thigpen the crew force became the most disciplined in our Air Force. It was capable of penetrating hostile airspace at night in a low-level mountainous environment covertly to execute any number of unconventional warfare missions.
