    Abstract

    A new modeling structure is proposed for the unsteady variation of aerodynamic coefficients of a delta wing aircraft. The model is based on suitable modulation of the static data with lagged incidence rate. The novel modeling structure is shown to be consistent with the static, small amplitude forced oscillations and the large amplitude sinusoidal response characteristics of a delta wing wind tunnel model with a sweep angle close to 60 degrees. 13; 13;
