Overview of Status of Analysis, Design, Fabrication, Tests, etc.
The sponsors have looked over the designs for the fabric housing tube. Though unsure of the need for the change in design, they have given us the permission to go through with out design and implement it to the sled. If this design works better, then it may replace the old method of housing the fabric sheets. Designs regarding the segmented anode sheets are still being discussed with sponsors and team members.
Accomplishments from Previous Week
The frame of the sled has been completely welded, including all the joints, using stainless steel rods. This will avoid corrosion at the welds.
The materials for the blades and the mounts have been received. The blades have been cut and milled to the correct dimensions. The mounts are being cut and milled to the specified dimensions.
The order for the stainless steels tube for the anode sheet has been placed.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish milling the blade mounts to the correct dimensions. (Everyone)
Weld the mounts to the frame of the sled and the blades to the mounts. (Mark)
Cut the bottom cover of the sled and the front cover from the stainless steel sheet. (Jeff and Ernest)
Finalize decision of anode segmentation and wiring. (Everyone)
Purchase tarp for anode segmentation design testing. (Kyle)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
5/2: The sponsors expressed concern with the design of the Delrin caps for the anode housing tube. Because there is a slight dip in the slot to prevent the rod from coming off, the amount of fabric rolled about the rod will be reduced. The sponsors did not want any designs that will cause the amount of fabric capable of fitting in the tube to be reduced. The team will probably change the design to get rid of the dip and have the Delrin caps capable of rotating 90 degrees to avoid the rod from slipping out.
There is still some concern as to how the team is going to insulate the wire connections. For testing purposes, caulk was used to secure the anode fabric and the wires.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
5/2: The professor wondered if the force simulation on the blade mounts was for a solid piece. Because the blade mounts will be three separate pieces welded together, a new simulation will be done and the welds of those three pieces will be incorporated for a more accurate simulation.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
None
Risks and Areas of Concern
The weight and ability to test the sled is still an issue.
The insulation of the wires is a big problem because the wire connections cannot be exposed to the water.
Resources or Information Required but not Available
None
Schedule
Finish welding the sled together
