Abstract: In order to accelerate the algorithm speed of dynamic model of helicopter, an IDRA approach for modeling helicopter was proposed and a dynamic model of six degrees of freedom (6 DOF) combining flying and landing was established in this paper. As the dynamic model is derived from the Lagrange equation of a non-conservative system, treating micro displacements and rotating angles of airframe in a simulation step as generalized coordinates, the relationship between energy dissipation, kinetic energy, potential energy and the generalized coordinates was analyzed. Finally, the reliability of this method and real-time of dynamic model were verified on the experimental platform of helicopter flight simulator, which could provide reliable theoretical foundation for solving the retardance of data transfer of helicopter simulator.
