Comp Design

Alison Thompson

• Megan Spee payload updates?

  • ABS print in the bay now (holds max 2.7 L). Likely doesn’t need priming for material to be watertight, but would like to test with water hold overnight/long time to make sure.

  • designing “cap” for tank that will also attach to peggy arms (through the bottom plate).

  • Specced a bunch of fittings (https://discord.com/channels/776618956638388305/1293366172518973572 ) in linked thread. most are aquarium style fittings, but not sure how the seals will act on a 3d print. Would like to order them asap for testing!

    • Uses 1/4” OD tubing. also, if someone can double-check the water pump <> tube:

      • 1/2" female BSP -> 1/4" OD push to connect - https://www.amazon.ca/uxcell-Straight-Connect-Purifiers-Connectors/dp/B07WGRLN3D - because this one assumes BSP threads on the water pump, and I’m not 100% sure on that.

Megan Spee perception of fittings assembly:

topmost 4 components referenced in discord thread.

• Jievan Tapajna Victor Sun pump + valve updates?

• Camilo Artigas Alos landing gear updates?

  • The base design is done, currently looking into implementing anti-tipping bars and create two different configurations for each approach of water retrieval.

• Agapa Goombs clamping block updates?

IMACS

Smile Khatri

• Monitor mount is done. Everything has arrived Calum Chisholm

  • 

  • May need to drill larger holes for the acrylic. To be tested tomorrow

Eclipse (Fixed-Wing) Airframe

Evan Janakievski

• Following fixed-wing sync discussion yesterday, might make adjustments to the airframe of Eclipse

  • POR is to use one battery now, can decrease size of the bottom plate or even get rid of it (this would require it being underneath pixhawk not sure about EMI issues)

    • No EMI issues w/ mounting Pixhawk above the battery confirmed by Daniel - Smile

• Tail boom support first version was made. Have some adjustments for Sam Wong

  • Can probably use just one space now that we are only aiming for one battery. And if we switch to two batteries can make adjustments as necessary

• Drawings by Justin Liu

  • Good start, can we schedule a call to go over these together following midterms?

Tracking Antenna

Sohee Yoon

• Agapa Goombs any new updates on the base plate redesign? Tracking Antenna Base Plate Redesign

  • Integration is done with the main assembly with a few minor changes to the bottom plate.

  • Gemini Plate standoff mounts were added as well.

• Angle Limiter: I’ll order more material to waterjet because of tolerance

Fuselage

Sohee Yoon

• Calum Chisholm any new updates on the fuselage design? Fuselage Design

  • Once that is done, let Victor Sunknow so that he can adjust the frame

  • Deadline: Does next week sound reasonable?

Wings

Nathaniel Li

• Sohee Yoon great work on the FEA study!

  • Didn’t fracture even at theoretical max lift force during takeoff

  • Possible fracture at higher lift forces occur at the cutout beside the spar cutout and closer to TE

    • This shouldn’t be a concern unless we go past our targeted velocity of 30m/s and undergo max lift

• Reviewing aileron design options

  • 
  • 

• Start manufacturing after midterms

• New tasks:

Empennage

Smile Khatri

Thushanth Parameswaran

• Design completion by end of October

• POR to use 2 rods for the spar for the HS and 2 for the VS

• Going with tapered VS.

Landing Gear

Ben Lovegrove

• Front landing gear is done and cheese holes are added

• Rear landing gear CAD is done

  • I’m going to be doing sims soon
