Abstract :
An approach to finding numerical solutions of certain initial-value problems involving infinite-delay singular neutral differential equations is presented. Such systems arise in the study of the motions of airfoils placed in 2D unsteady flows and play an important role in controller design for aircraft flutter suppression. The two-step procedure starts with truncating the infinite-delay term and is dependent on the specified initial data. For the second step, a fully discretized approximation scheme that can be used to find approximate solutions for the associated finite delay equation is outlined
