3. 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
4. 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
5. 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
6. 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
7. 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
8. 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
9. 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
