An improved graphical visualization for the subsonic-steady aerodynamic of delta wings using matlab of delta wings using matlab

الملخص EN

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 flow field 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 convicted 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.
