As light as possible

Mitigate vibration on camera if possible (this isn’t the top priority but nice to have)

Task Progression/Updates

INITIAL IDEAS

I’m thinking of just a simple sheet metal plate with a right angle bend bolted to the 30.5x30.5mm grid on the frame, open to other ideas if you have them though!

First Glance Notes

  • I am thinking the flanges on the side could be removed and the part could be squared off for weight savings. If we see it needs more stability could be added in the future

  • Will need to 3D print a mount for the camera that then mounts to this. Looks like there is space reserved above the motor for that currently. Vibrations may be a concern, but can be addressed later if a major issue

  • Not sure if there is more possibility for weight savings, which there may be but @Alison Thompson may have thoughts.

  • I agree with Evan, side flanges as implemented here aren’t really helping

  • How does the camera mount to this? a 3d print?

  • Can this be added to the fixed wing main assembly with the motor mated to it in the way you’re envisioning?

  • All corners should be filleted

  • idk simulations but @Evan Janakievski may be able to help with a sim to see if we can expect this to bend with no supports

  • can look at sheet metal or 3d printed braces to support the motor mount from behind if we expect it to bend

  • once in main assem and camera mount is in there we can see if we can reduce the height of the top flange/round it off

  • I think this part should be a part of the frame assembly, unless others oppose please move there and change naming accordingly

  • part should be the thickness of 14ga aluminum (~1.63mm) (that’s what we can bend)

  • make sure bend radius is at least equal to the material thickness

  • Need to filet the corners on the mount once the design is finalized.

  • I prefer this squared off. I can adjust the plate of the frame if there is some overhang from this that causes issues

  • The flange the motor will be mounted to can be cut down and not be as thick. Whatever is necessary once you see the motor mated to it

  • Spoke with Smile about mount. Thinking that moving it down would be best to ensure we don't have as much vibe. This may also benefit us as it is more level with COG

  • New design request would use two brackets, one below main plate and one above. The top bracket would have space for camera. See below

  • Follow similar shape to current design

  • Removed excess material to shave off unnecessary weight

  • Adjusted the camera mount to be similar to current one on pegasus

  • Changed all clearance holes to use hole wizard

  • Wires from motor will wrap below the bottom mount.

  • Not sure about FOV of camera and if the motor would be visible

    • Can move it to be further ahead or move it below

  • Moved motor upwards as shaft is not removable and needs room within the fuselage now

  • Moved camera mount to the outside of the plate

  • Changed bend radius to 1/32 in.
