Team #1: Brandon Fichera Dave Rabeno Greg Pease Sean Gallagher Sponsor: Dr. Stephanie Wright Delaware Aerospace Academy Advisor: Dr. Michael Keefe Mission Statement: To design a two person hovercraft for the Delaware Aerospace Academy that will demonstrate the scientific principles of a hovercraft, foster teamwork between students, and provide a fun, safe, and educational environment for all students involved.

Team #1 Summary BackgroundBackground – Mission – Approach Customers Wants and ConstraintsWants and Constraints Metrics for the Wants Functional Benchmarking and Best PracticesFunctional Benchmarking and Best Practices Concept GenerationConcept Generation Concept Evaluation against MetricsConcept Evaluation against Metrics Schedule –up to now –the rest of the semester –budget

Team #1 Approach Continue to develop customer’s wants and the metrics for those wants Based on these wants and benchmarking, develop multiple concepts Narrow down concept field, perform lift and thrust calculations, start pricing fans and motors Present the chosen hovercraft concept in such a manner that maximizes both fun and education

Background Delaware Aerospace Academy: Involved in past U of D senior design projects. Specializes in teaching kids about the technology involved in the space program. Hovercrafts: New and exciting technology that has yet to be widely distributed. Team #1

Problem Description Needs and Benefits: Educational Tool School Demonstrations Teach Hovercraft Principles Increase Interest in Science and the Space Program Delaware Aerospace Tech Camps (Level III) Teamwork and Cooperation Teach Hovercraft Principles / Mechanics Team #1

Constraints Size of door in Spencer Lab (4.5’ by 6.3’) Allowable Funds ($1600) Number of pilots (2 or greater) Operation (must be able to hover)

TriflyerHovercraft PegasusHovercraft Universal HovercraftHovercraft Kits Hover ClubHovercraft Articles Science ProjectSimple school project

Smithsonian Air&Space Museum use videos to excite peoples interest Six Flags Amusement Parks use acceleration and jerk for fun Briggs and Stratton Engines HP, RPM and price Elibra / Hovertech Magnetic levitation Grainger Industrial Equipment and Supplies Electric Motors RPM, HP and price Universal Hovercraft Fan designed for personal hovercrafts Caterpillar Heavy Lifting Cranes

List of Metrics # Principles taught & method of presentation –Visualization of flow –# visible moving parts Pilot Cooperation –Steering Method –Thrust Control Speed of vehicle Maneuverability –Turning radius –range of motion –directions of travel Power source –Battery lifetime / fuel capacity –fuel efficiency Labor hours of construction

List of Metrics Aesthetics –# Colors and Lights –# Sound effects Obstacle Course –success rate –time Price Size & Weight Maximum Component Stress Component lifetimes Clearance Maintenance-hours per flight hour

Concept Generation & Evaluation Against Metrics Educational & Fun 1) Smithsonian Approach - show a short video on the principles and science and then allow children to experience it first hand 2) Amusement Park Approach - let two children operate it and describe the science of it during operation Video allows for better and more thorough explanation but might lose kids’ interest if not careful In Amusement Park approach, children may not learn as well but will be less likely to become disinterested »Choose: Smithsonian Approach How can we satisfy our mission statement in various ways?

Concept Generation & Evaluation Against Metrics Magnetic levitation is too expensive Suspension craft is too bulky and expensive. Doesn’t demonstrate appropriate principles Choose: Fans and Air Cushion Fuel cells are too expensive Choose: Either gas and/or battery (electric) powered Type of Lift Power Supply Magnetic levitation Electric Fan(s) and air cushion Liquid Fuel Suspension Fuel Cells

Concept Generation & Evaluation Against Metrics Maneuverability Fan System Human powered - push and pull - weight shift (steering) Rocket Thrusters & Jet Engines Rocket Thrusters and a jet engines are not safe Human power doesn’t meet range and speed target values. Choose: Fan System
