This is our payload / magnetorquer board CAD. It’s responsible for both the payload and our specific ADCS, just to save on space. (Note: in space engineering, this is usually NOT a good idea: you want things to be modular - if a PCB fails, you don’t want too many things dependent on it... but here, we’re okay because we know what we’re doing and the system isn’t complex.)

Mechanical Work to do

• change the rods to 2.5 inch lengths each.

• center each rod on the mounting holes and please send me a photo from top down view.

• make the rods elevated from the board 1-2mm (adjustable) - distance mate

• re-design the aircoil based on me and Madhav’s specifications.

  • rectangular size: TBD (read Chat)
  • fastening sites: somewhere that makes sense and minimizes structural bending.
  • height/thickness: there should be enough space for X number of coils to be wound around it, with an acceptable clearance. go find the diameter of the copper wire used (ask Madhav). We don’t want this being too tall.

• Examples: look at AirCoil - Air Torquer - Magnetorquer | SatCatalog. Projects | Alex Boehm

• please design a way to fasten the rods and the aircoil together. Ie, some sort of clamp mechanism around the rods? feel free to adjust the aircoil design specifically for this feature. A lot of freedom here.

  • look at HELICOILS and whether they are acceptable for space compared to inserts. Report back on what you find.

• Determine: should the aircoil be 3D printed with HP PA-12 Nylon, or machined with Al6061? I want you to report to me the pros and cons of each method, specifically within a space engineering context. I’m curious what you come up with!
