  1. Effectiveness of Axiomatic DesignTools and Methods in Capstone Design • Overview of Axiomatic Design • Axiomatic Design Tools Symmetric Tree Decoupling Matrix • Case Study--Wright Flyer • Application Methodology

  2. Some Definitions • Axiomatic Design - Identification and classification of customer needs (FRs), aligning these with uncoupled design concepts (DPs) that can be efficiently implemented with local resources (PVs) • Supporting Concepts: • Functional Requirements (FRs)‏ • Design Parameters (DPs)‏ • Process Variables (PVs)‏

  3. Maximize Independence • Axiom 1 – Designs which have single function components or features are superior to design which require components to perform multiple functions.

  4. Minimize Complexity • Axiom 2 – Given that two designs meet functional requirements, the more robust design is the one that requires less information transfer between components and operators.

  5. Case Study: Wright Flyer

  6. Sub-system 1: Propulsion

  7. Sub-system 2: Stable in Air

  8. Sub-system 3: Stable on Ground

  9. Sub-system 4: Consistent Control

  10. Symmetric Tree for Wright Flyer
