Team Team Presentation Transcript

  • Team New ZealandTwo Boats or Not Two Boats?
    Tommy Robaina - Nicholas Holt - Brett DeRocker - RonakAmin
  • Introduction – Design of a Sailboat
    Introduction – Design of a Sailboat
  • Background
    1870 - Introduction of the American Cup (formerly known as The One Hundred Guinea Mug)
    Changes and Regulations
    Sailboat length and mast size
    Crew size
    Competition Structure
    Two groups
    Defenders
    Challengers
    Background
  • Racing Objectives – How to win
    Weight of the sailboat
    Drag factor
    Strength and stability
    High winds and sea conditions
    Crew
    Fitness/training as well as knowledge
    Racing Objectives – How to Win
  • Testing Methods – A Comparison
    Testing Method – A Comparison
    Tank and Tunnel
    Computer Simulation
    Construction of ¼ scale sailboat model
    Testing takes place in a water tank/pool with use of towing device and wind tunnel
    Test analyzes performance characteristics
    Use of computer software to analyze performance characteristics
    Asks for specific input data to analyze and calculate performance output
    Tools
    FEA
    CFD
    VPP
  • Computer Simulation Method
    Computer Simulation Method
    Advantage
    Disadvantages
    Speed
    Creation time
    Instant Results
    Cost effective in comparison to Tank and Tunnel
    Easy to compare alternative sailboat designs
    Simple to enter alternative parameters & receive results
    Eliminates the “Scale-up” problem
    Massive computing memory needed
    Physical prototype still necessary for basic hull and keel design
    Not completely self sustainable; requires additional extensive knowledge
  • Team New Zealand
    Objectives
    To win the Americas Cup in 1995
    Resources
    Syndicate of 50 members
    Management, Design and Construction Crew, Sailing Crew
    20 Million Dollar Budget
    Beneficiary of Silicon Graphics Corporation
    Access to powerful computer technology
    Team New Zealand
  • Dilemma Choices Faced by Team New Zealand
    Crafting of two boats of similar design at the same time
    Crafting of two boats of different design at the same time
    Craft one boat now, determine performance, and then based on that craft an additional
    Dilemma
  • Recommended Solution
    Craft one boat now, determine performance, and then based on that craft an additional
    Based case facts: this presents the most cost effective scenario
    Based on designer Doug Peterson’s previous design success
    Allocate to primary boat, test the performance, then determine the success of the design as well determine alterations to be made to second boat
