6. MULTIDISCIPLINARY APPLICATIONS AEROSPACE DESIGN AERODYNAMICS & ACOUSTICS

7. MULTIDISCIPLINARY DESIGN HIGH-LIFT DEVICES : 1 CRITERION / 1 DISCIPLINE : MAXIMIZE LIFT DRAG-BUFFETING : 2 CRITERIA / 1 DISCIPLINE : MINIMIZE CRUISE DRAG & MAXIMIZE Cz BUFFET AERO-ACOUSTICS & HIGH-LIFT DEVICES : 2 CRITERIA/ 2 DISCIPLINES : NOISE REDUCTION OF MULTI-ELEMENTS AIRFOILS DURING TAKE-OFF SUPERSONIC REGIME & BANG : 2 CRITERIA/ 2 DISCIPLINES SUPERSONIC REGIME & NOISE REDUCTION : 2 CRITERIA/ 2 DISCIPLINES

8. INTEGRATING MULTIDISCIPLINARY APPLICATIONS in VOs INTEGRATION OF PARTNERS’ EXPERTISE TO DEPLOY COLLABORATIVE APPLICATIONS NETWORKED PC-CLUSTERS, COMPUTERS & DATABASES TO SUPPORT MULTIDISCIPLINARY CHALLENGES HIGH-LEVEL PROCEDURES FOR CONCURRENT ENGINEERING (CSCW, VIRTUAL ORGANISATIONS & ENTERPRISES …) INCLUDE CAD/CAM, MULTI-PHYSICS SOLVERS & OPTIMIZERS, VR, DIGITAL MOCKUPS, …

9. SHOULD & CAN VOs EMULATE PROBLEM SOLVING ENV. ? HOW CAN COMPUTE & BUSINESS MODELS BE ADAPTED TO MAKE BEST USE OF VOs ? OPEN VO QUESTIONS WHERE DO VOs NOT MAKE SENSE ? WHAT IS THE REAL COST OF OPERATING VOs ? CAN VOs HELP FOR MULDISCIPLINARY APPLICATIONS ? HOW TO USE VOs FOR HIGH I/O APPLICATIONS ? HOW TO DESIGN VOs FOR HIGH AVAILABILITY ?

10. REQUIREMENTS NEED FOR VIRTUAL REALITY ENVIRONMENT NEED FOR CSCW PROCEDURES & SUPPORT NEED FOR GRID COMPUTING NEED FOR DISTRIBUTED DATABASE TECHNOLOGY NEED FOR FRIENDLY USER INTERFACES

11. Distributed Data Bases CSCW Local Solvers Deterministic/Stochastic Optimizers Validation codes RESEARCH CENTRES AND UNIVERSITIES INDUSTRY Industrial multi physics test cases High performance computers Local Databases Graphic analysis tools Validation guidelines Multi-Physics optimisation PC clusters GOVERMENT INSTITUTIONS Generic multiphysics test cases PC clusters Communication System Web-based system Computing System Grid computing environment Concurrent engineering platform VO PLATFORMS

12. MAY OVERLAP & SPECIFIC VIEWS FEDERATED RESOURCES DYNAMIC COLLECTIONS DISTRIBUTED USERS & RESOURCES DISTRIBUTED ALLOCATION MANAGEMENT & SCHEDULING VO FUNCTIONALITIES SUPPORT MEMBERSHIP & ACCESS PROTOCOLS SCALABLE & ROBUST ARCHITECTURE & PROTOCOLS

13. EASY ACCESS & CONTROL OF APPLICATIONS VIRTUAL GROUPS, PROJECTS, TEAMS… ? VALUE ADDED INCENTIVES vs. CURRENT RELUCTANCE VO : WHAT IS MISSING ? FILLING THE GAP BETWEEN TECHNOLOGIES SHARING DATA BETWEEN VIRTUAL REALITY & CAD/CAM SOFTWARE SEAMLESS INTEGRATION WITH LEGACY APPLICATIONS

14. VIRTUAL REALITY IS TECHNOLOGY HERE ALREADY ? DISTRIBUTED APPLICATIONS STEERING VO : OPEN ISSUES CSCW ROBUST SHARING OF RESOURCES INTERACTIVE REAL-TIME CHANGE MANAGEMENT

15. CONCLUSION CONCEPT FOR BEST USE PRACTICE FOR EXISTING GRIDS ? IF NOT, IS VOs ADDED-VALUE SO OBVIOUS ? IF NOT, WHERE & HOW IS ADDED-VALUE ADDED ? PROVOCATIVE & PESSIMISTIC ARE VOs NECESSARY ? WHERE DOES ADDED-VALUE MAKE SENSE ?

16. CONCLUSION « THE DIGITAL DYNAMIC AIRCRAFT » LARGE DYNAMIC COLLABORATIVE ENVIRONMENTS OPTIMISTIC
