Book excerpt: A half-scale Unmanned Aerial Vehicle (UAV) was designed and constructed from composite materials for the Flight Research Lab at the Naval Postgraduate School. The vehicle was designed as a technology demonstrator for two studies. First, the Tilted Ducted Fan (TDF) vertical flight capability engine and its stability and control systems, and second, for the tail configuration testing for longitudinal and lateral-directional stability enhancement of an existing tailless Unmanned Aerial Vehicle. Completion of these research and test objectives should provide the configuration requirements for a full-scale development vehicle with vertical takeoff and landing with transition to the forward flight mode.

Download or read book Composite Materials in Aerospace Design written by G.I. Zagainov and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 463 pages. Available in PDF, EPUB and Kindle. Book excerpt: Composite Materials in Aerospace Design is one of six titles in a coherent and definitive series dedicated to advanced composite materials research, development and usage in the former Soviet Union. Much of the information presented has been classified until recently. Thus each volume provides a unique insight into hitherto unknown research and development data. This volume deals with the design philosophy and methodology used to produce primary and secondary load bearing composite structures with high life expectancies. The underlying theme is of extensive advanced composites research and development programs in aircraft and spacecraft applications, including the space orbital ship `BURAN'. The applicability of much of this work to other market sectors, such as automotive, shipbuilding and sporting goods is also examined in some detail. The text starts by describing typical structures for which composites may be used in this area and some of the basic requirements from the materials being used. Design of components with composite materials is then discussed, with specific reference to case studies. This is followed by discussion and results from evaluation of finished structures and components, methods of joining with conventional materials and finally, non-destructive testing methods and forecasting of the performance of the composite materials and the structures which they form. Composite Materials in Aerospace Design will be of interest to anyone researching or developing in composite materials science and technology, as well as design and aerospace engineers, both in industry and universities.
Download or read book Small Unmanned Fixed wing Aircraft Design written by Andrew J. Keane and published by John Wiley & Sons. This book was released on 2017-08-29 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small Unmanned Fixed-wing Aircraft Design is the essential guide to designing, building and testing fixed wing UAVs (or drones). It deals with aircraft from two to 150 kg in weight and is based on the first-hand experiences of the world renowned UAV team at the UK’s University of Southampton. The book covers both the practical aspects of designing, manufacturing and flight testing and outlines and the essential calculations needed to underpin successful designs. It describes the entire process of UAV design from requirements definition to configuration layout and sizing, through preliminary design and analysis using simple panel codes and spreadsheets to full CFD and FEA models and on to detailed design with parametric CAD tools. Its focus is on modest cost approaches that draw heavily on the latest digital design and manufacturing methods, including a strong emphasis on utilizing off-the-shelf components, low cost analysis, automated geometry modelling and 3D printing. It deliberately avoids a deep theoretical coverage of aerodynamics or structural mechanics; rather it provides a design team with sufficient insights and guidance to get the essentials undertaken more pragmatically. The book contains many all-colour illustrations of the dozens of aircraft built by the authors and their students over the last ten years giving much detailed information on what works best. It is predominantly aimed at under-graduate and MSc level student design and build projects, but will be of interest to anyone engaged in the practical problems of getting quite complex unmanned aircraft flying. It should also appeal to the more sophisticated aero-modeller and those engaged on research based around fixed wing UAVs.

Download or read book So You Want to Design Aircraft written by Jean Broge and published by SAE International. This book was released on 2018-05-30 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: The market for aerospace composites is projected to reach $42.97 billion by 2022, up from $26.87 billion in 2017, at a CAGR of 9.85% from 2017 to 2022. Clearly, the use of aerospace composites in commercial aircraft has gained momentum during the past few decades, but there is still much room for growth and much more to learn. Lightweighting is generally considered to be the main driver for the increased and pervasive use of composites. However, beyond the contribution toward fuel efficiencies, composites also offer increased resistance against corrosion and part count reduction. Those corrosion characteristics, as well as fatigue properties, lead to lower maintenance costs over aircraft and components manufactured using traditional materials. Commercial aircraft are complex, sophisticated engineering marvels. And while introducing composites into new programs has added many benefits, it has also added complexity. This book aims to help manage and mitigate that complexity. To reduce the learning curve, the book opens with a refresher of key criteria involved with the forming of aerospace components, and then moves on to take a provocative look at the real-world practicality of manufacturing composite parts to rigid, at times untestable, specifications. The book then segues into suggesting a few “rules of design” for manufacturing CFRP components to minimize or avoid common production problems, and then into more specific manufacturing tools and processes that could enable larger and more complex component geometries, while retaining specific material properties and maintaining part functionality. Ultimately, readers will be enlightened to the potentials of aerospace composites, and empowered to include them at the beginning of any aerospace development program, from the smallest component to entire airframes.

This book was released on 2018-07-18 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Efforts focused on the use of thermoplastic composite materials in the development of structural details associated with an advanced fighter fuselage section with applicability to transport design. In support of these designs, mechanics developments were conducted in two areas. First, a dissipative strain energy approach to material characterization and failure prediction, developed at the Naval Research Laboratory, was evaluated as a design/analysis tool. Second, a finite element formulation for thick composites was developed and incorporated into a lug analysis method which incorporates pin bending effects. Manufacturing concepts were developed for an upper fuel cell cover. A detailed trade study produced two promising concepts: fiber placement and single-step diaphragm forming. Based on the innovative design/manufacturing concepts for the fuselage section primary structure, elements were designed, fabricated, and structurally tested. These elements focused on key issues such as thick composite lugs and low cost forming of fastenerless, stiffener/moldine concepts. Manufacturing techniques included autoclave consolidation, single diaphragm consolidation (SDCC) and roll-forming.
