PDM

@Smile Khatri

  • Nathan may have saved PDM (goat)

    • deleted old IP address on the license server so now there is only 1. If your PDM is not working, let us know.

    • Should be on ‘PDM-SelfHost’ in Zerotier. If you got PDM prior to Winter 2024 you may need a new zerotier ID.

Peggy Payload

@Alison Thompson

  • Both payloads looking good

  • Waiting on filament to come to print final tanks

Peggy Landing gear

@Alison Thompson

  • Angled landing gear manufacturing almost done!

  • Just need to do the CF tubes on Saturday and we can assemble

  • We will fly with this new landing gear on Nov 30th!

  • Tipping bars blocked by filament delivery as well, testing to see if we actually need them when landing gear is done

Peggy Frame

@Alison Thompson

  • Remade bottom panel today

  • Will send to e3 for cutting

    • @Shawn Henry Dragon @Victor Sun are the panel edits in CAD ready?

  • New clamping design for arm blocks looks good, need to print more when filament comes and cut aluminum - we will just use the bandsaw to cut the old pieces

Peggy 2 Jig

@Evan Janakievski

  • There were good adjustments to work with the new landing gear

  • I left feedback on what was not good on the Pegasus 1 jig to try to fix for this one

  • Should be ready for manufacturing soon

    • With the limitations on waterjet, do we still want to go with gussets?

Wings

@Nathaniel Li

  • Pushing aileron CAD

  • GPS mount was redesigned by @Evan Janakievski

Groundstation (IMACS)

@Smile Khatri

  • @Sam Sayad @Sacha Missaghian

  • Any updates on the groundstation?

  • Almost finalized design

  • Ping Nathan into the design review

Tracking Antenna

@Sohee Yoon

Fuselage

@Sohee Yoon

  • Currently I'm changing the dimensions of the panels, hoping to finalize this by this weekend or early next week

    • Working on making the height of the fuselage taller to avoid overlap with the frame and I’ve lengthened the front portion to accomodate for the motor mount changes

    • Because of the thickness of the boards (~4mm slightly below), the fuselage overlaps with the wings, so I’ll need to make cutouts of the wings on the side panels. Does anyone else have a better idea for this problem?

Current state of CAD
  • Need to grind as much manufacturing and assembly as possible before finals

  • Plan to have the frame assembled by next week and get started on wings + empennage manufacturing

  • We should have all the parts we need to make the plane

  • To make a good VTOL we need to be able to make a good fixed wing
