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.

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

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.

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

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]
