Ansys whitelist is closed. If your members did not fill it out, they will not be able to install Ansys.
The frame is detached from the shell. Thank you to everyone who helped out!
Next steps are refilling and rebleeding the brakes. This is to test the motor and try to recreate the conditions that caused controls to fault at comp
TLDR: Controls system faults when we accelerate too fast or go above a certain max speed. Unsure what the issue is, perhaps motor controller config
ClickUp use has not been satisfactory
Don’t just fill out ClickUp because we tell you to
It is a tool that will make your life easier. Once it is up-to-date it takes minimal effort to maintain it so long as you do it constantly
This is also a way for me to keep track of everyone’s progress. I don’t only want to have progress checks during meetings, but it also isn’t sustainable for me to text each one of you to ask about progress
Don’t want to micromanage but it seems we have this reminder every week
Ideally in the future we should just be able to pull up ClickUp for these meetings and ask about progress
we need to define how we are going to do reference points on the mold, and confirm that the knowledge is transferred
Aerodynamics
We need to solidify the plan for splitting up work and creating different parts of the shell(nose, tail, how to we avoid it messing up the overall geometrey)
Talk about roll cage in an intersystem meeting, because thats the next big thing that defines what we do
Composites
Figure out design of windshield with respect to the polycarb and what materials we should use
LOTS of wesley notes, not worth putting all in this spot since its lot of smaller specific notes
resin infusion is a risk and will cost a lot of money (vacuum)
consider having aeroshell PDR at the same time as dynamics and frame CDR
Higher cooling efficiency than air, uniform cooling, less power allocation, won’t have to worry about positive/negative pressure in battery
regs say we HAVE to have airflow within battery box, need to clarify if heat pipes are an actual substitute. Also this level of cooling might not even be necessary depending on cells
Airflow Cooling
Aeroshell - air intake/exhaust
Battery
Frame - Space, duct routing
Previous design, simpler to implement, less testing/calcs needed to design/verify
more fans → more power needed, worse cooling efficiency and nonuniform. Nose intake might not be within regs

Aeroshell:

Weekly Updates
Need to do more daybreak work
Might need to redo/rethink some of the cooling solution due to new regs
Adjust module mounting and bus bar location since we are removing load from midpanel
Daybreak Progress
Extending daybreak controls arms by 2
BPS and Contactor layout complete
Main enclosure complete, need to add mounting locks and roller wheel
Dashboard layout and connections finalized - controls has v1 done, waiting for review and order
Opened up battery and identified broken modules. Prat and Frank will have ppl go up and start fixing it to start motor testing.
