Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • Discussed coupler his experience with low stiffness couplers (5/5)

  • Came up with multiple plans moving forward (5/5)

    • Plan A: Obtain a coupler (purchased or manufactured)

    • Plan B: If cannot make a coupler, avoid RPMs which cause resonance. For our case we would want to stay under 8000 RPM

    • Plan C: Manufacture a fly wheel and avoid RPM which causes resonance. Quickly rev past 5500 RPM or stay below that RPM

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Talked with Gillett about designing and manufacturing coupler. Recommended team to talk with Delson and/or people from SME (email, 5/5/18)

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • None

Risks and Areas of Concern
