This paper introduces a rocket model and discusses the advantages of refining it using a variable-structure approach to remodel critical parts. Both versions of the model are implemented in Modelica and were simulated using Dymola as simulation environment. The DySMo framework; which supports the simulation of variable-structure models in common simulation environments; was used to facilitate the redesign. The general benefits of the variable-structure approach are presented; and on the basis of the rocket model we present that simulation time and the data volume of the simulation can be reduced while maintaining the accuracy of the simulation results.

Keywords: Variable-structure modeling; simulation speed; data reduction; reduce equation stiffness; rocket launch
