  1. Magnetic suspension and levitation train -Vana Richards -Logan Chalfant Mentors: Dr. Yusuf Hascicek & Mr. Yalcin Akin

  2. I. Our Project

  3. The HTS Team • Tuesday morning research update meeting. • Lead by our mentor, Dr. Hascicek. • Attended by Yalcin Akin, our graduate student mentor, and the other in-lab researchers.

  4. Schematics and models

  5. Rail Systems • We tested possible rail systems for durability and levitation.

  6. Testing the Superconductors • Batch 1: Appeared not to be superconducting. • Batch 2: Marginally superconductive – even after oxygenation. • Batch 3: Melted by its own protective epoxy coating.

  7. Maglev Prototype

  8. The Physics

  9. Magnetic Flux Lines • All magnetic objects produce invisible lines of force that extend between the poles.

  10. Meissner Effect/Perfect Diamagnetism • Magnetic field lines penetrate most objects. • However, below their Tc and Hc , superconducting materials exclude field lines (flux).

  11. Magnetic levitation • Demonstration of the Meissner effect.

  12. Crystal Lattice • There are often imperfections in the superconductor’s lattice structure. • YBCO crystal lattice structure

  13. Flux Pinning • Flux tubes penetrate the lattice and become affixed to the imperfections.

  14. Magnetic Suspension • Click on the picture to start the movie. • Once pinned, an elevated magnet can suspend a superconductor beneath it.

  15. III. The History of Magnetic Levitation Vehicles

  16. 1750 – John Mitchell conducted the first experiments measuring the magnetic forces between the poles of a magnet . The principle of magnetic force is critical to Maglev train operation.

  17. 1900 – Robert Goddard and Emile Bachelet conceive the concept of frictionless trains.

  18. 1969 – American scientist James R. Powell and Gordan T. Danby patented the first design for Maglev trains.

  19. 1970 – German and Japanese engineers start research and development towards their versions of Maglev technology.

  20. 1990 – The initial phase of the Yamanashi Maglev Test Line commences.

  21. 2003 – The Shanghai Transrapid Maglev Line is inaugurated.

  22. III . The Future

  23. Maglev Trains • Room temperature superconducting magnets • Generating energy at faster speeds using less energy at lower cost

  24. NASA • Maglev technology could give space vehicles a “running start” to break from Earth’s gravity.

  25. Maglev Space Propulsion • Launching systems would use magnetic fields to levitate and accelerate a vehicle along a track . • Reaching the end of the track, the vehicle could switch to more conventional rocket engines.
