  2. Agenda • Address MSD I Phase V customer and guide concerns (Action Items) • Completed circuit and wiring diagram • Gear, motor and reel connectivity • Test plan update • Phase Deliverables • Gate Review Materials • Week 5 Vision • Imagine RIT Plan/Elevator Speech

  3. Final System Concept Major changes: • Better gear system design

  4. Action Items Update

  5. Final Motor Selection The motor and corresponding bracket arrived this week and is in the Energy and Motion lab (motor and two batts are checked) AndyMark 9015 Motor (am-0912) Specifications: Physical Specs: • Overall Length : 8.19cm (3.19 inches) • Motor Body Length 5.68cm (2.24 inches) • Weight : 226.79g (0.5 pound) Performance Specs : • Voltage : 12 VDC • RPM : 16,000 • Free current : 1.2A • Max power : 179W • Stall torque : 60.64 oz-in (428m-Nm) • Stall current : 63.8 A connect with 26.9:1 gearbox

  6. Checked two WKA12-5F2 batteries - active Tested motor - cw/ccw rotation, visual inspection Battery & Motor

  7. Final issues before testing Control Directional Control of the H-Bridge

  8. Directional control of H-Bridge Logic input voltage (3.3V - 5V) -> 4.4V

  9. Gears 24 Tooth 32 Tooth

  10. Permissible Surface Speed (1 of 2)

  11. Permissible Surface Speed (2 of 2)

  12. Axial Load/Compressive Strength

  13. Compressive Strength 1760 4900

  14. Out of Stock Gear Solution

  15. Power Transmission Shaft • Plan to order a solid cylindrical shaft and machine in D profiles where the collars are located. • Upgraded to stainless steel for added corrosion resistance.

  16. Power Transmission Shaft • Calculation performed to determine maximum deflection of the shaft under load. • Maximum deflection = 0.0378 in.

  17. Power Transmission Shaft • Calculation performed to determine the risk of shaft buckling. • The minimum force required to cause our shaft to buckle is 67,566 lbs.

  18. Collars • Upgraded to stainless steel collars for added corrosion resistance. • Waiting to hear from McMaster on set screw strength properties.

  19. Test Plans

  27. Risk Management

  28. Gate Review Materials

  29. Imagine RIT Plan Manning the booth • Exactly two members will be present at all times. Each team member serves 2 hours minimum, either back to back or separately. Technical Presentation • Show Makani and Ampyx videos, our own flight videos (unless we produce bad quality videos or the project doesn’t work) • Poster Kid-Friendly Presentation • Suk’s Wind Turbine Science Kit • Kite • Pinwheels • Wind draft parachute

  30. Imagine RIT Elevator Speech The wind energy base station high altitude glider is our team’s project. This project seeks to explore the option of using gliders attached to a tether to generate power to reduce or eliminate the need for large, costly windmills and to take advantage of the stronger and more consistent winds found at higher altitudes. This is a fairly new area that is just gaining traction in the professional world with companies like Makani, Ampyx, and Google each trying to come up with the most efficient design. To generate this energy in our type of glider design, the glider is flown in a ovular path up in the air. When flying into the wind, the tether is reeled in. This is because the glider slows down and the reeling in motion compensates for the slack generated by the loss of speed. When flying with the wind, the tether is reeled out. The tether winds around a reel that is connected to a generator, causing generation of electricity due to the mechanical energy. Ideally the power generated will be greater than the power used to reel in. This was proven theoretically by Glen Gavi’s master’s thesis and we are seeking to prove it in a practical setting. Our team of seven engineers from the mechanical electrical sectors is the first step of this research group, so will be providing a path parallel to the ground is possible by running the glider without a generator component. Our tasks included designing the base structure itself, a power transmission system, a bridle system, and various electrical equipment. [Whoever is talking can talk more about what they did here]
