This book was released on 2018-05-23 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: Calculated numerical values for some aerodynamic terms and stability Derivatives for several different wings in unseparated inviscid incompressible flow were made using a discrete vortex method involving a limited number of horseshoe vortices. Both longitudinal and lateral-directional derivatives were calculated for steady conditions as well as for sinusoidal oscillatory motions. Variables included the number of vortices used and the rotation axis/moment center chordwise location. Frequencies considered were limited to the range of interest to vehicle dynamic stability (kb

Download or read book Calculation of Unsteady Transonic Aerodynamics for Oscillating Wings with Thickness written by S. Y. Ruo and published by . 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 1976 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report investigates the rolling-up of vortices over and behind wings of low and high aspect ratios, and simultaneously the evaluation of the aerodynamic characteristics including the spanwise and chordwise pressure distributions on the wings. The present method is based on the extension of the Vortex Lattice concepts also to low aspect ratio wings and the rolled-up vortex which is established over as well as behind the wings. The computer program, which was developed, is capable of reproducing the results of the Vortex Lattice Method (VLM) for linear aerodynamic coefficients for high aspect ratio wings. The wake effect is included in the modified VLM program. This wake calculation showed that the center of the tip vortex is very near the wings' tip for the high aspect ratios wings. The non-linear aerodynamic characteristics are evaluated when the vortices are shed over the wing and begin the rolling-up process from the leading edges. This effect is particularly important for wings of low aspect ratios.
