Why modeling such complex system? Analysis of the supersonic rocket Architecture Analysis and Design Language
(AADL) Model conceived Validation case Improvements and evolutions
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
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
Hybrid decomposition◦ Black box method◦ Reverse engineering
Advantages :◦ System for each function◦ Model close to real ARES
rocket
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
Modeling
Simple check
Computational check
Computational check - example
Need to validate performances computed
Test on Ares04Evo-Leia (2011)
Improvements on current model :◦ Better modeling of Cx, Thrust
Evolutions :◦ Toolbox for preliminary design
Requirements automatically checked for subsonic configuration
Improvements on REAL◦ New patterns◦ New functions
Base for a preliminary design tool for PERSEUS project
