This paper presents the application of model based design for the development of a real-time flying quality evaluation simulator named NALSim, built around Windows platform. NALSim is a novel rapid prototyping system based on MatlabR, SimulinkR and the Real-Time-Windows TargetR, applicable for fighter, transport and unmanned air vehicles/micro air vehicles simulations. The simulator uses state of the art modeling and simulation technologies to validate various design and flying quality concepts. NALSim is developed such that it is scalable and low cost. The paper presents the simulator architecture and its application for flying qualities. A novel non linear Least Squares optimization based methodology is proposed for efficient handling quality studies.
