156B Week 7

Current Status - Rings inside the chamber has been unmounted and need to remount them.

During last week, we had the problem of waistband seal ripping. As of solution, we bought the neoprene glue that was recommended by our sponsors. We currently have two types of neoprene glue which can be alternative if the one does not work. Lastly, we got the news that our temporary mount of rings with tapes has fallen of and need to remount them. We have ordered the seam sealer and the vinyl cement to mount the rings.

Goals for Next Week.

• Waistband seal testing - Test if the neoprene glue can fix the ripped waistband seal.

• Mounting Rings - Remount the rings with sewing and cement.

Sponsor Comments from Last Meeting (02/16/21).

• Locking Mechanism - No longer a priority and need to focus on fixing the leakage issue.

• Pressure Gauge - Will be used for data acquisition.

Instructor Comments from Last Meeting (02/18/21).

• Mounting rings - Suggestion of using elastic bands

• Waistband seal

(1) Customization of seals for each astronauts

(2) Having of replacement seal in case the ripping happens again.

Risks and Areas of Concern

• Ring Mounting, having them in place

• Prevention for future seal ripping
