Available in PDF, EPUB and Kindle. Book excerpt: This is an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs), which present some of the richest problems intersecting science and engineering. The agility and spectacular flight performance of natural flyers, thanks to their flexible, deformable wing structures, as well as to outstanding wing, tail and body coordination, is particularly significant. To design and build MAVs with performance comparable to natural flyers, it is essential that natural flyers' combined flexible structural dynamics and aerodynamics are adequately understood. The primary focus of this book is to address the recent developments in flapping wing aerodynamics. This book extends the work presented in Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).

This book was released on 1975 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: An analytical approach is presented to account for some of the nonlinear characteristics of the transonic flow equation for finite thickness wings undergoing harmonic oscillation at sonic flight speed in an inviscid, shock-free fluid. The thickness effect is accounted for in the analysis through use of the steady local Mach number distribution over the wing at its mean position by employing the local linearization concept and a coordinate transformation. Computed results are compared with that of the linearized theory and experiments. Based on the local linearization concept, an alternate formulation avoiding the limitations of the coordinate transformation method is presented.

This book was released on 2018-07-23 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: A comprehensive experimental investigation of the pressure distribution over a semispan wing undergoing pitching motions representative of a helicopter rotor blade was conducted. Testing the wing in the nonrotating condition isolates the three-dimensional (3-D) blade aerodynamic and dynamic stall characteristics from the complications of the rotor blade environment. The test has generated a very complete, detailed, and accurate body of data. These data include static and dynamic pressure distributions, surface flow visualizations, two-dimensional (2-D) airfoil data from the same model and installation, and important supporting blockage and wall pressure distributions. This body of data is sufficiently comprehensive and accurate that it can be used for the validation of rotor blade aerodynamic models over a broad range of the important parameters including 3-D dynamic stall. This data report presents all the cycle-averaged lift, drag, and pitching moment coefficient data versus angle of attack obtained from the instantaneous pressure data for the 3-D wing and the 2-D airfoil. Also presented are examples of the following: cycle-to-cycle variations occurring for incipient or lightly stalled conditions; 3-D surface flow visualizations; supporting blockage and wall pressure distributions; and underlying detailed pressure results.

Download or read book Theoretical Study of Air Forces on an Oscillating Or Steady Thin Wing in a Supersonic Main Stream written by Isadore Edward Garrick and published by . This book was released on 1947 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper constitutes a theoretical study of the aerodynamic forces on an oscillating or steady wing of finite span moving forward at a uniform supersonic speed. The treatment is based on the linearized theory obtained by considering only small disturbances in an ideal fluid. The wing is therefore considered to be a nearly flat thin surface at a small angle of attack and the flow is considered non- viscous and free of strong shocks. The theory in this case is equivalent to finding certain solutions of the wave equation in three dimensions with respect to a moving coordinate system.

Available in PDF, EPUB and Kindle. Book excerpt: Asymptotic solutions are obtained for the un steady pressure on wings and bodies that oscil late harmonically at high frequencies while in supersonic flight. The solutions have the form of series in descending powers of the frequency, and they include effects of three-dimensional flow and second-order effects due to the thick ness of the wing or the body. In the derivation, the oscillatory part of the flow is regarded as a perturbation superimposed on the steady isen tropic flow past the wing or body in the mean position, and a method of eikonal representation is applied to the differential equations and boundary conditions of the oscillatory flow. The results consist of (a) the first two terms of the series for three-dimensional wings with supersonic trailing edges andlongated pointed bodies, (b) the first three terms of the series for supersonic two-dimensional airfoils, and (c) the first four terms for very slender wings and bodies. The solutions (a) and (b) give the oscillatory pressure to the second order in thickness when the steady-flow distribution on the surface is known to this order from available theories or from experiment. The leading terms of the solutions coincide with the piston ap proximation while the higher terms depend directly on the curvatures of the surface. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Amid a welter of topics on the aeronautical engineering curriculum-hypersonic fluid mechanics, heat transfer, nonequilibrium phenomena, etc.-this concise text stands out as a rigorous, classroom-tested treatment of classical aerodynamic theory-indispensable background for aeronautical engineers and the foundation of current and future research. The present volume is also unique for its recognition of matched asymptotic expansions as a unifying framework for introducing boundary-value problems of external flow over thin wings and bodies. In addition, the book fully acknowledges the important role of high-speed computers in aerodynamics. After a short review of the fundamentals of fluid mechanics, the authors offer a fairly extensive treatment of constant-density inviscid flow. Chapter 3 deals with singular perturbation problems, presenting an extremely useful technique not to be found in most texts. Subsequent chapters give solid basic coverage of these topics: Chap. 4-Effects of Viscosity Chap. 5-Thin-Wing Theory Chap. 6-Siender-Body Theory Chap. 7-Three-Dimensional Wings in Steady, Subsonic Flow Chap. 8-Three-Dimensional Thin Wings in Steady Supersonic Flow Chap. 9-Drag at Supersonic Speeds Chap. 10-Use of Flow-Reversal Theorems in Drag Minimization Problems Chap. 11-Interference and Nonplanar Lifting Surface theories Chap. 12-Transonic Small-Disturbance Flow Chap. 13-Unsteady Flow Ideal as a primary or supplementary text at the graduate level, Aerodynamics of Wings and Bodies also offers working engineers a valuable reference to the resultsof modern aerodynamic research and a selection of new and useful analytical tools.
