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.

Jones and published by . This book was released on 1957 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A flutter investigation has been made in the Langley transonic blowdown tunnel at Mach numbers between 0.79 and 1.34 on a thin 10 degree sweptback wing having an aspect ratio of 4 and a taper ratio of 0.6. The data obtained have been compared with data from NACA Research Memorandum L55I13A for zero and 30 degree sweptback wings of the type investigated, the flutter boundary for the 10 degree sweptback wing falls between those for the zero degree and 30 degree sweptback wings in the low supersonic Mach number range. However, the subsonic level (around a Mach number of 0.8) of the flutter boundary for the 10 degree sweptback wing lies above those for the zero and 30 degree sweptback wings. In addition, the amount of rise in the flutter boundary from the subsonic level to the supersonic values is about the same for the wings with angles of sweepback of 10 degrees and zero degrees, but is much greater for the wing with an angle of sweepback of 30 degrees.

Download or read book Flutter Analysis of Rectangular Wings of Very Low Aspect Ratio written by Robert William Fralich and published by . This book was released on 1958 with total page 652 pages. 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.

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.
