Available in PDF, EPUB and Kindle. Book excerpt: Subsonic and transonic aerodynamic data for a wraparound fin configuration are presented. Free-flight aeroballistic tests to obtain these data were conducted at atmospheric pressure and over a Mach number range of 0.6 to 1.35. The aerodynamic coefficients and derivatives presented in this paper were extracted from the position-attitude-time histories of the experimentally measured trajectories using nonlinear numerical integration data reduction routines. Results of this analysis indicate that a dynamic instability exists above Mach 1.0 and is related to an out-of-plane side moment which is dependent of the pitch angle. The stability boundaries associated with this side moment are mapped. Designers should consider this moment whenever wraparound fins are used. Keywords include: WAF(Wraparound Fins), Aerodynamic stability, Side moment, Pitch-roll resonance, Folding fins, and Submunitions.

This book was released on 1998 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wall-mounted semi-cylindrical model fitted with a single wrap- around in (WAF) has been investigated numerically and experimentally, with the objective of characterizing the mean and turbulent flowfield near a WAF in a supersonic flowfield. Numerical and experimental results are used to determine the nature of the flowfield and quantify the effects of fin curvature on the character of the flow near WAFs. This research has been motivated by the need to identify possible sources of a high-speed rolling moment reversal observed in sub-scale flight tests. Detailed mean flow and turbulence measurements were obtained in the AFIT Mach 3 wind tunnel using conventional probes and cross-wire hot-film anemometry at a series of stations upstream of and aft of the fin shock/boundary layer interaction. Hot-film anemometry results showed the turbulence intensity and Reynolds shear stress in the fuselage boundary layer to be far greater on the concave side of the fin than on the convex side. Mean flow was also obtained in the AFIT Mach 5 wind tunnel using conventional pressure probes. Numerical results were also obtained at the test conditions employing the algebraic eddy viscosity model of Baldwin and Lomax. Correlation with experimental data suggests that the calculations have captured the flow physics involved in this complicated flowfield. The calculations, corroborated by experimental results, indicate that a vortex exists in the fin/body juncture region on the convex side of the fin. This feature is not captured by the oft- used inviscid methods, and can greatly influence the pressure loading on the fin near the root.

Download or read book Aerodynamics of Wrap-around Fins in Supersonic Flow written by and published by . This book was released on 2005 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing supersonic fin theory has been modified to compute the pressure distribution over Wraparound Fin (WAF). Evvard's theory has been used to calculate the pressure loading due to Angle-of-Attack (AoA) on a WAF by including fin curvature as a variable in the definition of zones of influence. Evvard's theory uses the intersections of the fin surface and the Mach cones originating from the leading edge discontinuities to split the fin surface into regions of influence. For a planar fin, the intersections are linear; however, the intersections on a curved fin form curved lines. By redefining the Mach lines to account for fin curvature and using an empirically derived induced AoA, the application of Evvard's theory can be extended to accurately compute the unique aerodynamic characteristic of WAFs.
