156A Week 10

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Considering design utilizing 3-D printing and rotating shafts seals

  • Research on what disturbs fish is wrapping up

  • Beginning test phase for leaking through 3-D printed parts and shaft seals.

Accomplishments from Previous Week

• • Risk Reduction Tests have been selected.

  • Pressure test tank has been procured.

  • Specimen for Risk Reduction have been selected and are being designed.

  • Materials for Risk Reduction Test have been purchased.

  • Research on what disturbs fish has been completed.

  • Steve’s 3-D printer has been calibrated

  • Reached out to Sponsor to talk to Scripps engineers

  • Reached out to Dr. Popper, an expert on noise disturbances to fish, got a reply

  • Wrote Test Procedure and Conditions for passing for leak test under pressure

  • Analysed muscle wire

  • Created a model based upon aircraft equations of motion

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Complete Design and Manufacture of 3D printed elliptical cylinder - Matt

  • Complete Design and Manufacture of 3D printed tube w/ threads - Janelle

  • Aid in manufacture - Steve/Sam

  • Test Specimens - All

  • Prepare Final Presentation - All

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • Paraphrased from sponsor: Discuss with my engineers about anything related to “building.”

    • We discussed and learned from his engineers on staff.

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • Paraphrased from Dr. Hoople: Narrow down risk reduction (RR) and work towards those

    • We decided that our RR will be on leaking through porosity and rotating shafts, and through research of what disturbs fish.

  • Paraphrased from Dr. Gillete: Look into Muscle Wire

    • We researched it and did some basic analysis for its use on a control surface.

Risks and Areas of Concern

• • That the measures we have chosen to stop leaking won’t work

  • Not being able to measure sound intensity under water

Resources or Information Required but not Available

• • Procuring enough information to produce specs regarding fish disturbances to validate “minimal Disturbance.”

Schedule

• • Completion of Risk Reduction Tests

  • Complete the Presentation due next Tuesday

Budget (list amount spent and amount remaining)

• • Spent: $ 119.80

  • Remaining: $ 2380.20

Progress on Report and Web page

• The webpage has been created.
