Budget Meeting is this Wednesday at 7:30pm
due tomorrow
Info session #2 is tomorrow
arrive at 6:15 wearing your Solar shirt
room TBD, likely at UTC 2.112A if we can get access to the projectors
LEADS: tba - might be delayed to another day or after info session
Budget
Please make revisions by tomorrow night
not enough links and justifications
review sid’s comments and make revisions
Design Duration
Designs for Daybreak were rushed
not enough research and validation was done
timelines were missed and design was constrained to ab a semester
bad/uninformed decisions were made
We cannot repeat the same methodology for the new car
design season cannot be condensed into one semester - Gerard wants to extend design perhaps into march
take time to do proper research and validation to inform our decisions and avoid poor designs
Cesar’s proposal to condense aeroshell manufacturing into 3 stages
no need to rush molds
proposal to send the top shell mold first that is only affected by the array
when height is determined move onto canopy
bottom shell ready → can start sending bottom shell out to be manufactured
avoids compromising designs and letting the molds sit around
2 months to get foam in and 4 months to waterjet
larger top shell this year and smaller bottom shell - ideas for connection still being developed - sizes are not dependent because this time to top shell will be on top of the bottom shell
Onboarding should allow members to develop a strong foundation
likely will have one more meeting about onboarding before freshies arrive
new members will work on Daybreak - almost exclusively
returning members can start working on the new car but have 1 project manager / assigner for example
we should explain the car’s issues, but also inform them what good designs look like so they have a basis from which to reference
issues and good alternatives as a lesson / learning experience
give them resources and examples to show them what a good design should be - then review their designs
go though their designs and walk them through pros and cons, allowing them to revise afterwards iteratively until a satisfactory design is achieved
goal is to establish a good foundation of design intent and experience
PDR / CDR will likely be moved later
Division/System Requirements

Ideas
3 vs. 4 wheel
suspension 101 /wiki/spaces/LHRSOLAR/pages/172426809 3 wheel stuff
frame and aeroshell constraints?
rear suspension attachment
Composite Frame
have research done by saturday to gerard
likely will have presentation at workday
assignments:
Aeroshell
wheel cover profile and attachment
airfoil for suspension components
drag force
Look at good attachment mechanisms for frame to shell
Fergo
designing chassis for rear trailing arm suspension - Josh
figuring out brakeline routing in 3 wheel
optimize CG location (roll cage, ballast position, driver position - leaning back?)
- Kenta
Dynamics
implementation of swing arm suspension for rear wheel - Kayla
shocks
suspension travel
pullrod v pushrod
THREE WHEEL BULLSHIT - Kayla
3 wheel steering characteristics for 3 wheel (Ackermann vs. Anti-Ackermann), correcting understeer in 3 wheel - evan
unsprung - three wheel will increase the loads of the assemblies so they need to be lighter weight, rear unsprung changes - sami
manufacturing related yapping - maybe whatever changes that we want to implement this year that has some relevance to our design intent - harshit
Emech
pack manufacturing techniques and pack design (split design) - Parthiv
