Hub Bub Odd (2017 Science Olympiad)

thingiverse

The Wind Whirl Wind is a very simple Wind Power wind turbine for the 2017 division C Science Olympiad, based on the original Wind Whirl. It should be fully rules compliant but check dimensions before using this design. The Wind Whirl Wind is an easy to attach hub that allows 1/8" wooden dowels to be used to attach fins to the CD. Unlike the original Wind Whirl, the Wind Whirl Wind is based on sets of three fins and not four. The Wind Whirl Wind comes in two flavors, a three (3) and a six (6) fin configuration. Note that you will need a printer able to print things fairly dimensionally accurate or you will spend a lot of time either gluing or sanding the dowels. The dowels should be firm while in place but still removable. Helpful note, glue to the 'shiny' side of the CD. Design Project: Project Apollo ==================================================================== Printed Parts needed: 1x Wind Whirl Wind - Three -or- 1x Wind Whirl Wind - Six ==================================================================== Hardware Needed: 1x 1/8" Dowel Rod 48" long 1x Super Glue 1x Standard CD ==================================================================== Info on Installing: Hub and CD : Glue the Wind Whirl Wind to the shiny side of the CD using Super Glue. The 'rings' should be the part of the Wind Whirl Wind attached to the CD. Dowel Rod : Cut the dowel rods to length to meet the rule set. Attach the fins to the dowel rods and insert dowels into the Wind Whirl Wind. ==================================================================== Info on the Design: Both the Wind Whirl and the Wind Whirl Wind were created to allow for rapid testing of different fin designs for the Wind Power Science Olympiad Competition. I have tried to keep the weight down as it turns out that it has a massive effect on the efficiency of the blades. Overall, it is a very simple design that should give the user of the Wind Whirl or Wind Whirl Wind the ability to iterate fast and test reliable. Note: At time of upload, the design has not been tested in competition and has no guarantee of performance. Print Settings Printer Brand: Printer: Resolution: Infill: Rafts: Supports:
