AN IMPROVED GRAPHICAL VISUALIZATION FOR THE SUBSONIC-STEADY AERODYNAMIC OF DELTA WINGS USING MATLAB

Abstract

The MATLAB programming language is used to write a generalized computer code to numerically simulate the aerodynamic of a lifting surface using the general vortex-lattice method. This code is used to model the flowfield and predict the aerodynamic loads. The subsonic, steady aerodynamic of a delta wing is used as an example. The powerful graphical tools of MATLAB are used to produce the following: 3-D visualizations of the wakes with/without hidden-line removal, the roll-up of the leading edge wakes, the propagation of the convected vortices, and 3-D pressure distributions. The results obtained in the present work support the physical interpretations of the wing-rock phenomenon and the multi-surface interference previously investigated by many authors; yet with significant improvement on the graphical visualizations.
