156A Week 10

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

• Individual Component Analysis in progress

• 3-D printers

• Nitrogen supply tube to nozzle connection material

• Nozzle material

• Nozzle shape

Accomplishments from Previous Week

• • Scope of project defined

  • Working environment of project understood

  • Nozzle designs brainstormed

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

• • Risk reduction presentation (All)

  • Individual Component Analysis (All)

  • Brake Design Challenge (All)

  • Fatigue Homework (All)

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

• • Prepare nozzle designs as soon as possible

    • Sketches are being brainstormed

  • Get prototypes out as soon as possible

    • CAD models of preliminary designs are being made so that 3D printed prototypes can be manufactured

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

• • Come up with specific individual component analysis

    • 1. Nozzle Material. (Layon)

    • 2. 3D Printer Comparison. (Edwin)

    • 3. Nozzle and tube connection

    • 4. Nozzle Design - Different shapes

  • Experiment to test gas distribution from various nozzle designs

    • Thermochromic ink

Risks and Areas of Concern

• • The high precision requirements will make manufacturing even prototypes costly

  • Testing of said prototype

  • New parts cannot interfere with system in place

  • Carbon-fiber tubes sometimes crack when cut causing gas leaks in tube

Resources or Information Required but not Available

• • Manufacturing cost estimates

  • Information on nitrogen supplying system

Schedule

• • Meetings with Sponsor Tuesdays at 2pm

  • Group meeting after Sponsor meeting

Budget (list amount spent and amount remaining)

• • $0 spent

  • $5000 remaining

Progress on Report and Webpage

• • Initiating
