Download or read book Relationship Between Flutter Parameters and Generalized Aerodynamic Forces for Wings of Low Aspect Ratio written by Bernard Mazelsky and published by . This book was released on 1962 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: A set of closed-form approximations is derived which relates the flutter conditions of a wing to its generalized aerodynamic forces. A simplified two-mode analysis is used to obtain a firstorder approximation. More general analyses are performed by treating additional effects as perturbations. The derivations are applicable to a wide class of low-aspect-ratio wings and apply to subsonic, transonic, supersonic, and hypersonic flow.

Available in PDF, EPUB and Kindle. Book excerpt: A flutter analysis, employing slender-body aerodynamic theory and thin-plate theory, is made for rectangular wings of very low aspect ratio with a constant thickness. The spanwise variation of wing deflection is assumed to be given by a parabola, and the chordwise variation is allowed complete freedom. The results show the vsriation of flutter speed and male shape with aspect ratio. Comparisons are made with additional resuits obtained by approximating the chordwise deflection shape by use of parabolic or cubic curves. The analysis shows that the cubic approximation gives good resuits for a ratio of chord to semispan less than 3.

Download or read book Basic Principles of the Indicial Lifting surface Flutter analysis Procedure written by Bernard Mazelsky and published by . This book was released on 1962 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A method of flutter analysis utilizing indicial functions to represent the unsteady aerodynamics is described. Basic concepts are illustrated for a two-dimensional wing; the extension to a spanwise distorting wing is also discussed. Significant aerodynamic parameters pertinent to a highly swept, hypersonic delta wing are reviewed. For these wings the principal factor for adequate prediction of flutter is determination of the steady and quasi-steady aerodynamic influence coefficients. The unsteady contributions are shown to have a negligible effect on the flutter characteristics.

Download or read book Unsteady Transonic Flow written by Marten T. Landahl and published by Courier Dover Publications. This book was released on 2019-04-17 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This classic monograph on unsteady transonic flow — the flow of air encountered at speeds at or near the speed of sound — is of continuing interest to students and professionals in aerodynamics, fluid dynamics, and other areas of applied mathematics. After a brief Introduction, Swedish physicist Mårten T. Landahl presents a chapter in which the two-dimensional solution is derived, succeeded by a discussion of its relation to the subsonic and supersonic solutions. Three chapters on low aspect ratio configurations follow, covering triangular wings and similar planforms with curved leading edges, rectangular wings, and cropped delta wings, and low aspect ratio wing-body combinations. The treatment concludes with a consideration of the experimental determination of air forces on oscillating wings at transonic speeds.
