| Control Line Reefing Part | Completed | Alex Chen |
Purpose:
The control line reefing part holds the line cutters and cuts the reefing line at 1500 ft.
Requirements:
Must hold the line cutters such that they have no displacement or rotation
Must fit on the piston and under the u-bolt without interfering
Details/Design:
Material: Aluminum 6061 T6
Mass (from CAD model): 0.15 lbs
Safety Factor: tbd
The line cutters reefing part contains the line cutters and cuts the control line at 1500 ft. It has two manufactured holes and a hollow interior in order to fit the line cutters. The control line is threaded through a hole in the top and the bottom. The structure contains a central tapped hole to screw onto the piston.

Manufacturing:
Plan
- Turn on lathe and then follow with mill until part neets dimensions.
- Tap center hole
Testing:
- Ground testing:
- During the first ground testing, line cutters jolted upwards during piston deployment and broke the 3D printed control line reefing part. Part was then redesigned and replaced to be aluminum.
- During the second ground testing, aluminum part held the line cutters successfully
- Wind Tunnel Testing:
- tested the line cutters' ability to cut the control line. Test was successful.
