Um einen Ornithopter auf Basis eines Flattermechanismus zu bauen, muss zuerst ein Katalog mit Parametern gefunden werden, welche das aerodynamische Verhalten des Systems beeinflussen. Das Ziel dieser Masterarbeit ist das Entwickeln und Dokumentieren einer Testroutine zur Findung dieser Parameter. Zu diesem Zweck muss ein Testaufbau entwickelt werden. In diesem Testaufbau kann der ungeregelte Mechanismus vertikal schweben. Während des Schwebens können Parameter wie Motorspannung, Motorstrom, Flatterfrequenz und Flughöhe bestimmt werden. Um die Auswertung zu vereinfachen wird der Testaufbau über einen Arduino mit Matlab als Steuersoftware gesteuert. Nach der Entwicklung des Testaufbaus müssen die verwendeten Sensoren und der Arduino verbunden und programmiert werden. Basierend auf dem derzeitigen Stand der Technik wird anschließend ein Flattermechanismus entworfen und aufgebaut. Der Mechanismus wird im Testaufbau getestet und optimiert, sowie die Parameter, die ein Schweben erlauben dokumentiert. In einer Parameterstudie können anschließend die Einflüsse verschiedener Parameter getestet werden. So kann ein Flattermechanismus entwickelt werden, der stabil schweben, und in Zukunft fliegen kann.

A poetic and nuanced exploration of the human experience of flight that reminds us of the full imaginative weight of our most ordinary journeys—and reawakens our capacity to be amazed. The twenty-first century has relegated airplane flight—a once remarkable feat of human ingenuity—to the realm of the mundane. Mark Vanhoenacker, a 747 pilot who left academia and a career in the business world to pursue his childhood dream of flight, asks us to reimagine what we—both as pilots and as passengers—are actually doing when we enter the world between departure and discovery. In a seamless fusion of history, politics, geography, meteorology, ecology, family, and physics, Vanhoenacker vaults across geographical and cultural boundaries; above mountains, oceans, and deserts; through snow, wind, and rain, renewing a simultaneously humbling and almost superhuman activity that affords us unparalleled perspectives on the planet we inhabit and the communities we form.

An investigation of the take-off, landing, and hovering-flight characteristics of a four-engine-transport, vertical take-off airplane has been conducted with a remotely controlled free-flight model. The model had four propellers distributed along the wing with thrust axes parallel to the fuselage axis. In order to produce direct lift for hovering flight, the propeller slipstream was deflected downward about 70 degrees by a full-span 65-percent-chord flap deflected 90 degrees and eight extensible vanes arranged above the wing in a cascade relation.

An updated and expanded new edition of an authoritative book on flight dynamics and control system design for all types of current and future fixed-wing aircraft Since it was first published, Flight Dynamics has offered a new approach to the science and mathematics of aircraft flight, unifying principles of aeronautics with contemporary systems analysis. Now updated and expanded, this authoritative book by award-winning aeronautics engineer Robert Stengel presents traditional material in the context of modern computational tools and multivariable methods. Special attention is devoted to models and techniques for analysis, simulation, evaluation of flying qualities, and robust control system design. Using common notation and not assuming a strong background in aeronautics, Flight Dynamics will engage a wide variety of readers, including aircraft designers, flight test engineers, researchers, instructors, and students. It introduces principles, derivations, and equations of flight dynamics as well as methods of flight control design with frequent reference to MATLAB functions and examples. Topics include aerodynamics, propulsion, structures, flying qualities, flight control, and the atmospheric and gravitational environment. The second edition of Flight Dynamics features up-to-date examples; a new chapter on control law design for digital fly-by-wire systems; new material on propulsion, aerodynamics of control surfaces, and aeroelastic control; many more illustrations; and text boxes that introduce general mathematical concepts. Features a fluid, progressive presentation that aids informal and self-directed study Provides a clear, consistent notation that supports understanding, from elementary to complicated concepts Offers a comprehensive blend of aerodynamics, dynamics, and control Presents a unified introduction of control system design, from basics to complex methods Includes links to online MATLAB software written by the author that supports the material covered in the book

Written by an internationally recognized teacher and researcher, this book provides a thorough, modern treatment of the aerodynamic principles of helicopters and other rotating-wing vertical lift aircraft such as tilt rotors and autogiros. The text begins with a unique technical history of helicopter flight, and then covers basic methods of rotor aerodynamic analysis, and related issues associated with the performance of the helicopter and its aerodynamic design. It goes on to cover more advanced topics in helicopter aerodynamics, including airfoil flows, unsteady aerodynamics, dynamic stall, and rotor wakes, and rotor-airframe aerodynamic interactions, with final chapters on autogiros and advanced methods of helicopter aerodynamic analysis. Extensively illustrated throughout, each chapter includes a set of homework problems. Advanced undergraduate and graduate students, practising engineers, and researchers will welcome this thoroughly revised and updated text on rotating-wing aerodynamics.
