Design
This should describe high-level distinguishing features of this subsystem. If this project is recurring (Space Race or IREC), focus on the items you judge would be important to tell the next year's team, especially specific improvements over previous years.
The Structure of FLDSMDFR has various key features. Past years contain a payload section, avionics bay, and recovery section. This year was different from previous years by including a poly carb tube, soda can, and a smoke flare.
The polycarb tube had allowed Payload’s camera get a clear view of flight. It was critical to get a good mount for the polycarb tube to the Blue Tube. We believe that this is where some issues may have arose. There had not been a clean cut on the Blue Tube, leaving a gap between the two sections. Another mistake was with the way we connected the two sections, the Bee Keeper’s had connected the two sections and then drilled the holes, we had drilled the holes then tried to connect them. It would be much easier to do it the same way the Bee Keeper’s had done.
The soda section had been secured using a 3D printed container. On the top it was sealed using a wooden bulkhead and was made sure to be water-tight. This was to prevent any liquid possibly ruining the structure of the Blue Tube.
In our design we needed to be aware of the mass and space that smoke flare would take up. This is important as the extra weight affects the center of gravity along with the fin flutter. Further details of the smoke flare can be found under recovery.
