    • Developing common methods for Aerospace PDE Results from the ENHANCE Project
    • Introduction to the ENHANCE Project What is ENHANCE?
    • “ ENHanced AeroNautical Concurrent Engineering”
      • European Commission RTD project (DG III + DGXII)
      • Strategic Objectives :
        • To define the new “Common way of working” in the European aeronautics industry throughout the whole supply chain
        • To substantially improve the competitiveness of the European aeronautics industry, by the search for standards and improvement in quality of data
      • Project Features :
        • A large 3 year R&D project (~260my effort), started in Feb 1999, 38 MECU
        • A wide partnership representing the whole aeronautics industry, with 14 main and 35 associated contractors spread over 10 different countries
    • The ENHANCE main principles
      • ENHANCE is aimed to harmonise methods and processes in the aeronautical industry
        • Same principles, milestones, standard parts catalogues, glossaries, etc.
      • ENHANCE uses existing tools (CAD-CAM, PDM, etc.) to validate its methods
        • Large business cases used as validation test beds
        • Collaboration between Aeronautical sector and IT vendors
      • ENHANCE is aimed to promote standards
        • At the European level (aeronautical industry standards)
        • Communication with other sectors
        • Communication with world-wide standardisation bodies
    • Technical Content Development Life Cycle CODECYMO COCONA Standard Contracts COPROMA Programme Management Life Cycle Model and Business Management Technology and Methodology for the Extended Enterprise Data Exchange IT Infrastructure Web-based Training COMEX COMTRAIN COMITIF COSUPP Aircraft Support COSCAL Scientific Calculation COCERP Certification Process Product Engineering Advanced PDM Concepts COPROMOD Standard Parts COSODA Multi-Site Collaborative Work COSITE Concurrent Engineering Integration and Experiments Business Case Studies Information Technology Management Support Dissemination & Exploitation

    • Advanced PDM Concepts The Digital Product Masters Concept
    • Enhance “Gem Stone”: the Digital Product Masters Concept
      • Successful Collaboration within the Extended Enterprise strongly depends on data to be exchanged.
      • Therefore the Digital Product Masters (DPM) Concept was developed
      • The DPM Concept provides a structure for the product information needed in the development of a new aeronautical product.
      • Within ENHANCE a DPM „Master Geometry“ was implemented within the PTC Windchill™ software.

      • A few issues were noted:
      • Performance improvement required: discussions are pending with IT developers
      • The AP209 interface is not widely implemented in commercial tools: only available with MSC/PATRAN preference NASTRAN
      • File oriented rather than object oriented: enable the independent import / export parts of data models rather than complete models

      • Use of pre-set routines from Mid-level library allowed the extraction of CFD data without difficulty
      • Process requirements within CFD application
      • An IT environment is required which integrates software tools and data exchange over networks in distributed multidisciplinary engineering processes

        • Provides improved control of the business process ;
        • Mitigates business critical risks on choice of Workflow Management System;
        • Facilitates Integration of Business Processes within the Extended Enterprise.
      • Few drawbacks:
        • Heterogeneous workflow development from geographically distributed locations is challenging ;
        • No insight in WF/WF status at other companies .
    • Conclusions on Standards
    • Feedback from the ENHANCE users
      • Though STEP is a conceptually an all-encompassing Product Data standard, it is defined in various sub-modules which leads to unnecessary complications for users.
      • The distinction between CAD and PDM translation is blurred by the presence of product structure within both domains.
      • There is a lag between CAD system functionality and STEP standards. PDM systems are evolving more rapidly than CAD systems and hence the lag between PDM functionality and STEP is even more behind.
    • Conclusion
      • ENHANCE
