Available in PDF, EPUB and Kindle. Book excerpt: Future high-lift systems must achieve improved aerodynamic performance with simpler designs that involve fewer elements and reduced maintenance costs. To expeditiously achieve this, reliable CFD design tools are required. The development of useful CFD-based design tools for high lift systems requires increased attention to unresolved flow physics issues. The complex flow field over any multi-element airfoil may be broken down into certain generic component flows which are termed high-lift building block flows. In this report a broad spectrum of key flow field physics issues relevant to the design of improved high lift systems are considered. It is demonstrated that in-flight experiments utilizing the NASA Dryden Flight Test Fixture (which is essentially an instrumented ventral fin) carried on an F-15B support aircraft can provide a novel and cost effective method by which both Reynolds and Mach number effects associated with specific high lift building block flows can be investigated. These in-flight high lift building block flow experiments are most effective when performed in conjunction with coordinated ground based wind tunnel experiments in low speed facilities. For illustrative purposes three specific examples of in-flight high lift building block flow experiments capable of yielding a high payoff are described. The report concludes with a description of a joint wind tunnel/flight test approach to high lift aerodynamics research. Fisher, David and Thomas, Flint O. and Nelson, Robert C.

Book Synopsis High-Lift Aerodynamics by : Jochen Wild
Download or read book High-Lift Aerodynamics written by Jochen Wild and published by CRC Press. This book was released on 2022-02-03 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a detailed look at high-lift aerodynamics, which deals with the aerodynamic behavior of lift augmentation means from various approaches. After an introductory chapter, the book discusses the physical limits of lift generation, giving the lift generation potential. It then explains what is needed for an aircraft to fly safely by analyzing the high-lift-related requirements for certifying an aircraft. Aircraft needs are also analyzed to improve performance during takeoff, approach, and landing. The book discusses in detail the applied means to increase the lift coefficient by either passive and active high-lift systems. It includes slotless and slotted high-lift flaps, active and passive vortex generating devices, boundary and circulation control, and powered lift. Describing methods that are used to evaluate and design high-lift systems in an aerodynamic sense, the book briefly covers numerical as well as experimental simulation methods. It also includes a chapter on the aerodynamic design of high-lift systems. FEATURES Provides an understanding of the physics of flight during takeoff and landing from aerodynamics to flight performance and from simulation to design Discusses the physical limits of lift generation, giving the lift generation potential Concentrates on the specifics of high-lift aerodynamics to provide a first insight Analyzes aircraft needs to improve performance during takeoff, approach, and landing Focuses on civil transport aircraft applications but also includes the associated physics that apply to all aircraft This book is intended for graduate students in aerospace programs studying advanced aerodynamics and aircraft design. It also serves as a professional reference for practicing aerospace and mechanical engineers who are working on aircraft design issues related to takeoff and landing.
Book Synopsis Secrets of a German POW by : Brian Brinkworth
Download or read book Secrets of a German POW written by Brian Brinkworth and published by Pen and Sword. This book was released on 2014-02-28 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the extraordinary story of Hauptmann Herbert Cleff, who was captured in Egypt during the Allied advance from El Alamein in November 1942. He was thought to have had some administrative function in the Panzer corps, but not all was as it seemed.It was found that he had expert knowledge about tanks, and was interrogated both in the Western Desert Theatre and after transfer to the UK, following assessments that he might prove useful to the Allied war effort. He began to reveal tantalizing glimpses of advanced scientific and engineering projects back in Germany, including the development of a secret new fuel, and progress with submarines, jet-powered aircraft, faster-thansound flight and long-range offensive missiles. The truth of Cleff's revelations could not be fully verified at the time, but some were accepted by key experts, which led to the start of a Most Secret project for a British high-speed research aircraft. Eventually, he decided to collaborate fully with his captors, with a view to bringing the war to an earlier end, though always insisting that the object was to destroy the Nazi regime, to the advantage of Germany in the long run. He was released into civilian life in 1943, to undertake work for the Ministry of Supply. Information gathered in Germany after the War now allows comparisons to be made by which the veracity of Cleff's claims can be assessed. Some firm conclusions are reached, but the motivation for his actions remains elusive. This highly original account is sure to appeal to anyone interested in fresh and diverting contributions to the unfolding history of the Second World War.

The scope of the book includes applications and topics of interest related to the simulation of high-lift configurations such as: lift and drag prediction, unsteady aerodynamics, low Reynolds effects, high performance computing, turbulence modelling, flow feature visualization, among others. This book gives a description of the state-of-the-art of computational models for simulation of high-lift configurations. It also shows and discusses numerical results and validation of these computational models. Finally, this book is a good reference for graduate students and researchers interested in the field of simulation of high-lift configurations.
Book Synopsis Uninhabited Air Vehicles by : National Research Council
Download or read book Uninhabited Air Vehicles written by National Research Council and published by National Academies Press. This book was released on 2000-06-28 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Air Force (USAF) planners have envisioned that uninhabited air vehicles (UAVs), working in concert with inhabited vehicles, will become an integral part of the future force structure. Current plans are based on the premise that UAVs have the potential to augment, or even replace, inhabited aircraft in a variety of missions. However, UAV technologies must be better understood before they will be accepted as an alternative to inhabited aircraft on the battlefield. The U.S. Air Force Office of Scientific Research (AFOSR) requested that the National Research Council, through the National Materials Advisory Board and the Aeronautics and Space Engineering Board, identify long-term research opportunities for supporting the development of technologies for UAVs. The objectives of the study were to identify technological developments that would improve the performance and reliability of "generation-after-next" UAVs at lower cost and to recommend areas of fundamental research in materials, structures, and aeronautical technologies. The study focused on innovations in technology that would "leapfrog" current technology development and would be ready for scaling-up in the post-2010 time frame (i.e., ready for use on aircraft by 2025).
