2. Overview The concept is to use magnets to stabilize and control the propeller, eliminating the need for conventional bearings and seals that eventually wear out and leak. The goals of this project are to design and create a working prototype mag lev propeller where there is no contact between the moving and stationary parts. Existing magnetic bearings may be used, or an entirely new design may be created. The end result is expected to be real-world adaptable in order for Boeing and other stakeholders to utilize in submersible ROVs.

3. Team Vision Goals ◦ Meeting with our customer and ensuring that the customer’s goals were communicated clearly with the team and that any confusion was sorted out. ◦ Create a problem definition that could be agreed upon. ◦ Create a practical user scenario that our project might end up being part of. ◦ To allow time for team bonding, which would create the best environment to complete the project in. Accomplishments ◦ We met with our customer twice, ensuring that there was no confusion and that our ultimate project goal was clear. ◦ Our problem definition has been created and agreed upon. ◦ The third goal of completing a practical user scenario can be seen in the flowchart in a few slides ◦ Lastly, as a team we have started to bond through our meetings, classes and work time spent together.

4. Project Summary The purpose of this device is to remove the need for any physical contact between the rotating and stationary pieces of the propeller system. ◦ It should remove the need for shafts, seals, and allow the propeller to be used in a submersible machine. Currently the levitated propeller design has been used on ROVs since the 1980s This design should make the propeller more efficient, have a longer life, prevent wear and leakage, and only has at most one point of contact. The desired result is to preferably create a fully magnetically levitated system that can be used for submersible ROVs for Boeing.
