  1. Modeling of a supersonic rocket using Architecture Analysis Language Naples, October 1st, 2012 Geoffrey Duval (ISAE-SUPAERO) Geoffrey.duval@isae.fr

  2. Table of contents • Why modeling such complex system? • Analysis of the supersonic rocket • Architecture Analysis and Design Language (AADL) • Model conceived • Validation case • Improvements and evolutions

  3. Why modeling such complex system ? • Context : PERSEUS project • Rockets conceived and built by students • New rocket each year • Usual needs : • Respect requirements • Quick evaluation of performances • Supersonic needs : • Architecture optimization • Formalize advanced project phase • Goal of the study : • To give efficient tool for preliminary definition of supersonic rocket

  4. Analysis of the supersonic rocket • Functional description of all requirements : • Service Function (FS) • Adaptation Function (FA) • Advantages : • Each requirement is specified with criteria and values • Easy definition of the success of the mission • Classification of requirements based on their importance

  5. Analysis of the supersonic rocket • Hybrid decomposition • Black box method • Reverse engineering • Advantages : • System for each function • Model close to real ARES rocket

  6. Architecture Analysis and Design Language • Allows to define a system as pair of component type and implementation • Compare implementation (technical solution) to system definition (model) • Architecture • Constraints • Performances • Using REAL (Requirements Enforcement and Analysis Language) for computation

  7. Architecture Analysis and Design Language • Modeling

  8. Architecture Analysis and Design Language • Simple check

  9. Architecture Analysis and Design Language • Computational check

  10. Architecture Analysis and Design Language • Computational check - example

  11. Validation case • Need to validate performances computed • Test on Ares04Evo-Leia (2011)

  12. Improvements and evolutions • Improvements on current model : • Better modeling of Cx, Thrust • Evolutions : • Toolbox for preliminary design

  13. Conclusion • Requirements automatically checked for subsonic configuration • Improvements on REAL • New patterns • New functions • Base for a preliminary design tool for PERSEUS project

  14. Thanks for your attention, Any questions ?
