Keywords: delta wings, unsteady, modeling, preliminary design, aerodynamic coefficient

An analytic prediction model is presented to estimate aerodynamic coefficient of delta wing undergoing dynamic motions. The model is based on the introduction of a state space variable describing the vortex breakdown. This model will be suitable for modeling of flight dynamics in the preliminary design phase.
