Tasks:

• create MIRO board Angelina Costa 22 Nov 2025 
• goals for Saturday meeting: flesh out load/environment and initial architecture design Adeline Vining Kareena Shah Angelina Costa  Yat Tik Wu Sreeja Akula 22 Nov 2025 
  • from progress on Saturday continue load/environment & initial architecture and potentially start thinking about structural interfaces

Next Steps:

• initial architecture
• load/environment definition
• structural interfaces in design
• block CAD
• read SMAD

Things to Consider for Structures:

1. Load/environment definition (mission requirements):

• load definition
  • (launch loads, vibrational)
• modal requirements ← Oligo might take of this
• internal pressure
• thermal (determine if we need a heating/cooling sys based on what electrical says)
• volume
• Oligo interface

2. Initial Architecture

• Baffles
  • structural integrity (sloshing & mixing), analyze materials & manufacturability (metal 3d printing), temperature 
• Tank
  • servos
• science system
  • cameras
  • thermocouple(s)
• Harnessing (work with electrical to account for this)
• Tank has to be exposed to the environment

→ What structural components are carrying the load? What is the load? How much load is it carrying?

3. Structural Interfaces

• Oligo interface (actual satellite)
• Are baffles welded to tank?
• Figure out all structural interfaces
• make ICD - interface control document
• will help with getting initial geometry

4. Materials

• validate and verify materials mentioned in paper
• Consider:
  • outgassing
  • thermal
  • structural/mass
• Falcon 9 user guide in resources (mostly for T&M)
• Come up with mass budget for each component
• E&M interference (electrical and magnetic interference)
• good material for thermal camera? (something that is thermally conductive but not E&M)

5. Block CAD

• model cad components as blocks
• figure out placements of everything and volumes
• e.x. tank is spinning: make sure wires/sensors don't get in the way
• get sizing

6. Initial Structural Analysis

• math & simulations

7. Detailed CAD

• exact geometries and looking at tolerances
  • leak testing
    • what O-rings, etc.

8. Detailed FEA
