Skeleton

Task Description

We want something (as light as possible!) that mounts to the 30mmx30mm M3 grid on the bottom of the drone and provides a base for the cabin pieces to be mounted to.

INITIAL IDEAS:

Wipeboard discussion in the bay, the current plan is to use thin carbon fiber tubes with tapped PEEK inserts to mount to the 30x30mm M3 grid on the bottom of the drone. 4 of these tubes can be attached to a carbon fiber plate (~1mm thick, ~4 layer layup) that can be used as the bottom of the cabin.

@Evan Janakievski to source CF tubes from Composites Canada and design the first revision of the skeleton. Tube diameter will need to be communicated to @Aric Quan for the aero-panel mounts.

First Iteration

• Used 10 mm diameter cf tubes

• PEEK inserts in the tubes to attach using M5 SHCS (need to change to M3s)

• 4 mm cf plate for the base

• Used dimensions of this cf tube from Composites Canada

  • https://shop.compositescanada.com/#/product/CFT-10x9TW

Notes after 10/04/23 Meeting:

• redesign dimensions of skeleton to fit to barbies shoulder to shoulder

• add lip on PEEK inserts that are width of the cf tube

  • 15-20 mm in length, hole tapped through

• cargo will be next to the cabin which allows for less height

• Barbie dimensions:

  • arm max width ~ 65 mm

  • height sitting ~ 250 mm NEED ACCOUNT FOR HEAD ROOM IN HEIGHT OF SKELETON

  • ~105 mm from bottom of foot to seat

  • ~ 145 mm for upper body

• Discussion with @Georgia Vachon Westerlund about design of skeleton and aeropanels will happen soon

FOR AEAC

Need to bring up cargo at the back instead of below and pros/cons of this.

I think despite equal number of pros and cons the drone being shorter and less CF is a big win and we should go with cargo at the back.

• Edited dimensions of skeleton to be wider and accommodate a wider passenger section

• Dimensions now are better equipped to hold cargo in the back behind passengers

• Added an overhang to the peek inserts to make sure it catches the cf tube

• Need to review dimensions of Barbies as current length of cf tubes is 20 cm, but I measured 25 cm as their seated height. Maybe if they are slightly reclined we can cut some height but still need head room

• Barbie dimensions:

  • arm max width ~ 65 mm

  • height sitting ~ 250 mm NEED ACCOUNT FOR HEAD ROOM IN HEIGHT OF SKELETON

  • ~105 mm from bottom of foot to seat

  • ~ 145 mm for upper body

  • Foot to back width ~ 90-95 depending on how knees are bent

• Adjustments to skeleton:

  • can lengthen base to the next holes and will gain about 90 mm

  • increase width of base to accommodate shoulder to shoulder of barbies sitting. Keep mounts where they are

  • height of tubes can be increased to about 260-275 mm while allowing head room for barbies

• Idea for cabin entrance would have it on the side and allow barbies to enter and sit like this?

  • Open

    

• Or other option would be to increase width even more and have an aisle between seats/be facing inward and seats ore on the sides.

Update from AEAC sync last night, cargo bay will be behind the passenger cabin due to pros and cons above.

Open

The holes drawn over in red are the holes used for mounting. The arrow on the pixhawk is pointing parallel with the long side of the hole mounts.

The distance between the holes is about 118 mm x 246 mm
