Available in PDF, EPUB and Kindle. Book excerpt: Uses advanced structural theories to formulate and describe the coupling between finite elements and classical aerodynamic theories Aeroelasticity using the Finite Element Method deals with the Aeroelasticity of lifting bodies (wings and panels) by the Finite Element Method (FEM). It focuses on Aeroelasticity problems related to wings and panels: wings in subsonic range and panel in supersonic regime are treated. The structural models used are built by using classical and advanced one-dimensional (beams) and two-dimensional models (plates/shells) for the analysis of metallic and layered structures made by advanced composite materials. The elastic problems are formulated by means of finite element method. The aerodynamic fields and loadings are expressed by considering known theories used in classical aeroelasticity analysis: strip theory (in both steady and unsteady form), Theodorsen models, Vortex Lattice Method, Double Lattice Method and Piston Theory. Static and dynamic aeroelastic responses are both addressed. Static (divergence) and dynamic (flutter) response, including panel flutter are detailed in the book. Formulates and describes the details of coupling between finite elements and classical aerodynamic theories. Proposes advanced 1D and 2D structural FE models in a form similar to the formulation used in classical beam, plate, shell theories. These advanced theories permit exploration of aeroelastic phenomena that are not considered by classical theories. Discusses classical aeroelasticity problems related to wings and panels. A valuable resource for Researchers in continuum mechanic of solids and structures

Available in PDF, EPUB and Kindle. Book excerpt: Few years ago, the topic of aerial robots was exclusively related to the robotics community, so a great number of books about the dynamics and control of aerial robots and UAVs have been written. As the control technology for UAVs advances, the great interaction that exists between other systems and elements that are as important as control such as aerodynamics, energy efficiency, acoustics, structural integrity, and applications, among others has become evident. Aerial Robots - Aerodynamics, Control, and Applications is an attempt to bring some of these topics related to UAVs together in just one book and to look at a selection of the most relevant problems of UAVs in a broader engineering perspective.

Available in PDF, EPUB and Kindle. Book excerpt: The fluid-structure interaction problem is studied for two different wing configurations based on moving grid techniques. These configurations demonstrate the interaction between a rigid structure and fluid, as well as the interaction between a flexible structure and fluid. A loosely coupled approach is used to perform the combined fluid and structure computations. The flow solver is based on an unsteady, implicit, three-dimensional, multi-block, pressure -based Navier-Stokes solver. The rigid structural model is based on a linear, time-invariant model derived via classical structural finite elements whereas the flexible structural model is based on a non-linear dynamic membrane model with the material obeying the hyperelastic Mooney's model. A suitable interfacing technique is incorporated to couple and synchronize the flow and structure solver. We present unsteady computations performed on a 45 degrees wing with sweep back as well as a membrane wing typically motivated by micro-air vehicle applications.

Download or read book Computational Techniques of Rotor Dynamics with the Finite Element Method written by Arne Vollan and published by CRC Press. This book was released on 2012-03-13 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: For more than a century, we have had a firm grasp on rotor dynamics involving rigid bodies with regular shapes, such as cylinders and shafts. However, to achieve an equally solid understanding of the rotational behavior of flexible bodies—especially those with irregular shapes, such as propeller and turbine blades—we require more modern tools and methods. Computational Techniques of Rotor Dynamics with the Finite Element Method explores the application of practical finite element method (FEM)-based computational techniques and state-of-the-art engineering software. These are used to simulate behavior of rotational structures that enable the function of various types of machinery—from generators and wind turbines to airplane engines and propellers. The book’s first section focuses on the theoretical foundation of rotor dynamics, and the second concentrates on the engineering analysis of rotating structures. The authors explain techniques used in the modeling and computation of the forces involved in the rotational phenomenon. They then demonstrate how to interpret and apply the results to improve fidelity and performance. Coverage includes: Use of FEM to achieve the most accurate computational simulation of all gyroscopic forces occurring in rotational structures Details of highly efficient and accurate computational and numerical techniques for dynamic simulations Interpretation of computational results, which is instrumental to developing stable rotating machinery Practical application examples of rotational structures’ dynamic response to external and internal excitations An FEM case study that illustrates the computational complexities associated with modeling and computation of forces of rotor dynamics Assessment of propellers and turbines that are critical to the transportation and energy industries Useful to practicing engineers and graduate-level students alike, this self-contained volume also serves as an invaluable reference for researchers and instructors in this field.

Download or read book Aeroservoelasticity written by Ashish Tewari and published by Springer. This book was released on 2015-03-24 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph presents the state of the art in aeroservoelastic (ASE) modeling and analysis and develops a systematic theoretical and computational framework for use by researchers and practicing engineers. It is the first book to focus on the mathematical modeling of structural dynamics, unsteady aerodynamics, and control systems to evolve a generic procedure to be applied for ASE synthesis. Existing robust, nonlinear, and adaptive control methodology is applied and extended to some interesting ASE problems, such as transonic flutter and buffet, post-stall buffet and maneuvers, and flapping flexible wing. The author derives a general aeroservoelastic plant via the finite-element structural dynamic model, unsteady aerodynamic models for various regimes in the frequency domain, and the associated state-space model by rational function approximations. For more advanced models, the full-potential, Euler, and Navier-Stokes methods for treating transonic and separated flows are also briefly addressed. Essential ASE controller design and analysis techniques are introduced to the reader, and an introduction to robust control-law design methods of LQG/LTR and H2/H∞ synthesis is followed by a brief coverage of nonlinear control techniques of describing functions and Lyapunov functions. Practical and realistic aeroservoelastic application examples derived from actual experiments are included throughout. Aeroservoelasiticity fills an important gap in the aerospace engineering literature and will be a valuable guide for graduate students and advanced researchers in aerospace engineering, as well as professional engineers, technicians, and test pilots in the aircraft industry and laboratories.
