Analysis
Things here
...
- The black, dark blue, and blue sets of lines represent the different vehicle weights (157, 167, and 177 lbs)
- The different lines within those sets represent the different launch angles
- These sets of lines follow the ascent and descent without parachute
- The light blue steady state descent lines represent descent with parachute

This schedule is fairly ambitious, but for most of these tasks I have already done the research or the preliminary analysis. Checkins before IAP are around the beginning of break,to size the dogue, and around the 1st to go over the design. I see the first week of manufacturing as a grace period if things get behind schedule. Other than the IAP trip, I'm free for IAP, so I can commit to working on this project.
Manufacturing
Manufacturing time
A disk-gap-band will take longer to manufacture. It's going to be larger than the previous drogues, probably around 4 ft. The band, while simpler to construct than the disk, will have to be joined together. Unlike our previous drogues, all of the 14 designs I've reviewed had skirt, vent, and disk tapes.
