In this study, dynamic model of an air platform (missiles and aircrafts) that has the ability to maneuver in all axes (displacement and rotation) and to follow another aircraft is achieved. Rigid aircraft mathematical models are adopted for the model aircraft and the calculations are done in a generic way excluding the effects of aeroelasticity. While considering the geodesic geometry of earth, the gravity model is also designed accordingly, and the atmospheric conditions at a given altitude are included in the calculations by using an atmospheric model. Depending on analysis purposes, it is possible to change the air platform degrees of freedom. Including degrees of freedom, for missile models, the user-defined definitions such as phase definitions, engine selections and customization of engine properties, seeker activation schedule and fuse type are configurable through an interface. Phase transition controls, motor controls, sensor activation/deactivation decisions are designed reasoning-based. To be able to enhance modeling flexibility and inject a reasoning capability, the models are designed as intelligent agents and they are modeled in Agent driven Simulation Framework (AdSiF). How a missile configuration is defined and how it is dynamically changed based on user interactions and user defined conditions are conducted using an agent-based modeling language. Furthermore, a novel approach for scripting and execution of the dynamic time frequency update is put forward in the study.
