Multi-granularity Modeling of Variable Structured Rocket based on Declarative Language
Wanmeng Zhou, Hua Wang, Fuyu Sun, Haiyang Li · 2015
The development of the rocket design process depends heavily on the effective and accurate modeling method. This paper elaborates the procedure to establish the variable structured rocket simulation package with the declarative modeling language Modelica. The package includes the rocket library with basic rocket components and rocket products with subsystems and segments. Some of the components like body and measurement take full advantages of the Modelica object-oriented characters, while others like control system and aerodynamics are assembled on the basis of traditional flight dynamics. The multi-granularity library for variable-structured rocket is verified with a case study. The results indicate that the library is successfully applied to the rocket modeling for flight control system design and is capable of rocket design in different phases.
