Morphological Chart and Concept Selection

Criteria for Concept Selection

1. Uses magnets for levitation

2. Can it operate underwater?

3. Is it safe?

4. Are there shafts and seals?

5. Will Boeing be able to adopt the design?

6. High flow of water

7. Is it completely waterproof?

8. Is it stable?

9. Keeps propeller and user safe

10. Not an electrical hazard

11. Programming is efficient and robust

12. Can be completed in 2 semesters

13. Easy to use

14. Cheap to produce

15. Efficient

16. Generates a lot of thrust

17. Friction-less and no mechanical wear

Fallback Options

• Gift shop design

• Partially levitated (1 single mechanical point)

• Propeller made to operate in air, if there is enough time we

will make it submersible
