A Conceptual Wing Flutter Analysis Tool for Systems Analysis and Parametric Design Study
نویسنده
چکیده
An interactive computer program was developed for wing flutter analysis in the conceptual design stage. The objective was to estimate flutter instability boundaries of a typical wing, when detailed structural and aerodynamic data are not available. Effects of change in key flutter parameters can also be estimated in order to guide the conceptual design. This userfriendly software was developed using MathCad and Matlab codes. The analysis method was based on non-dimensional parametric plots of two primary flutter parameters, namely Regier number and Flutter number, with normalization factors based on wing torsion stiffness, sweep, mass ratio, taper ratio, aspect ratio, center of gravity location and pitch-inertia radius of gyration. These parametric plots were compiled in a Chance-Vought Corporation report from database of past experiments and wind tunnel test results. An example was presented for conceptual flutter analysis of outer-wing of a Blended-Wing-Body aircraft.

A linear, aeroelastic analysis of a low aspect ratio swept back trapezoidal wing modeled as a cantilever plate is presented. An analytical and numerical formulation for both the aerodynamic forcing and structural response of the wing was developed. The analytical model uses a three dimensional time domain vortex lattice aerodynamic method. A Rayleigh-Ritz approach has been used to transfer equa...

The powering requirement of a land yacht is one of the most important aspects of its design. In this respect the wind tunnel testing is an effective design tool. In fact, changing the parameters of the vehicle and testing the changes in the wind tunnel will give us a better understanding of the most efficient vehicle, and yet it is time consuming, expensive, and has inherent scaling errors. Ano...
