@Alison Thompson & @Smile Khatri

Frame Updates

@Conall Kingshott

• New motor mounts from @Sohee Yoon looking great!

• Clamping leg blocks are coming along well.

  • Are we awaiting a review?

• Side shields are also looking good. Reviewing before meeting with Andy, but all seems on-track.

• We have weight problems. Drone as a whole is projecting around 10kg rn, our goal was 7. All subteams are doing everything they can to do reduce weight, and we need to do our part.

• Going to start moderate re-designing and lots of re-machining center block for weight savings

Cabin Updates

@Alison Thompson

• Talked at AEAC sync yesterday about our current ideas for the cabin

• Open

  

  We want to have a main “skeleton” for the cabin that we can iterate through aero pieces on the outside and find what works best

  • Current idea for mounting main skeleton is thinner CF tube with tapped threaded inserts mounted to the 30x30 grid on the bottom of the drone

• This will allow us to get something done fast for other subteams to test on and we can work on a more polished cabin while they test

• Considering cargo bay below or behind Barbies (We should disscuss, below could be a “safety” feature)

  • If cargo bay is below maybe stairs can be hidden away in there?

• We will need someone to design the basic version of the cabin and block off space for the cabin and cargo bay

• Someone to work on the interior (we want something light but feels realistic)

• Maybe a separate person working on the cargo bay (we want something light but feels realistic)

• Windows should end up existing but not integral to first rev

• Open to ideas!

• Task assignment in Asana time!

• mech leads can we get lightweight PLA plz?
