Mechanical

Notes on manufacturing status.

...

• Fuselage status?

  • STATUS: Panels cut & mounted?

    • not cut yet, but outlines traced and ready to be cut next work session or time @.sohee is on campus

  • Will be done this weekend

• Airframe is finalized, apart from maybe some slots that need to be milled into spars and tail boom if EE would like them

  • EE would like this, was confirmed in this meeting

  • Mech and EE to sync and figure out finer details Ryan Scomazzon Evan Janakievski Kenny Na

Wing

• STATUS: Lasercut ribs

  • Task for laser cutting will be given out shortly after meeting

• STATUS: 3D prints

  • All parts ready to print, will get those going

• STATUS: Manufacturing tasks given out?

  • Task for laser cutting will be given out soSplit into two sections: frame and wrapping

  • Frame: will be done by this weekend

  • Wrapping: will be done in 1 or 2 more work sessions (so by Feb 8)

• Timeline: initial prototype within 2 weeks (~ Feb 8), bit more for maiden flight

  • UPDATE: still on target?

    • Timing is looking good

landing gear

• STATUS: Bent and wheels mounted?

  • Waiting on one sheet metal part. Should be ready first weekend of february

  • placed ordered for the servo adapter for rear landing gear today

• Timeline: within next couple of weeks (~ Feb 1)

  • UPDATE: still on target?depends on order shipping, tentative ddl Feb 1

Empennage

• STATUS: linkages for the elevators and rudder

  • task assigned to Rohaan who’s on-site, just following up with him this week

• STATUS: need to 3D print the elevator and rudder

  • wasn’t 3D printed this weekend, planning for this weekend or earlier

• Timeline: within next couple of weeks (~ Feb 1)

  • UPDATE: still on target?

    • yes

Everything Mech is in last drawer in the red toolbox.

Avionics/EE updates

• Electrical Component status?

• WARG PCB BOM: Eclipse maiden flight BOM

  • single servo driver x 2

  • can splitter x 3

  • 6s servo module x 1

  • 6s power module ?

  • Redundant 5V buck x1

...

• STATUS: Redraw block diagram

• Jerry Tian will upload new block diagram

  after meeting

• Question: are we gonna use the GPS listed here? https://uwarg-docs.atlassian.net/wiki/spaces/ARCHS22/pages/2556133415/Fixed+Wing+2025#Electrical-Components In the old (Jun 2024) block digram, it’s connected to the CAN splitter but It doesn’t seem to support CAN?

  how

  • M9N GPS… Jerry Tian will verify with Daniel or Nathan regarding CAN capability

  • How many pitot tubes do we need? where do we want it to be placed at?

    • just 1, will be placed halfway down the spar of the left wing

• Harness timeline

  • Jerry Tian will host a session to familiarise more EE members with this

    Tentative

    physical harness done by Feb 23

• 6s Servo Module (EFS)

  • STATUS?

  • EFS: Hardy Yu PMing this, an onsite member was assigned to this yesterday so Hardy met with them today. No official progress on the task since last week but still on schedule since there isn’t too much left to do for this task. I believe Hardy found a possible work around to the external crystal oscillator issue but maybe he can update on that.

  • EE: to assemble rev 2 PCB

• 6s power module (EFS)

  • STATUS? (last week said we would set due date)

  • Research around the sensor/datasheet etc is finished. Began driver dev now. The CAN component will be very quick to implement since it’s very similar to our other CAN projects but don’t have a great estimate on how long driver part will take as it’s a capable member working on it but it’s his first driver. Open to due date suggestions or range and we can try to push it to be completed by then. Maybe Derek Tang has a better estimate in mind

• EE to finalize and order connectors

  • follow up in next eclipse sync

Timeline

• Foam Plane Pilot Training (first flight): Feb 2

• Ecplise Strapdown Test: March 1st/2nd

• Eclipse Maiden Flight Test: March 8th/9th

...

• Mechanical structure is done, just need to mount electronics (this will hopefully change before tuesday meeting)

• Validated the electronics

• Mounted everything other than the rudder servo

• Need to figure out link quality issues with our ELRS board

  • Kenny Na will come to foam plane work session next week Monday to check in on this

  • might happen due to automatic RF signalling upon bootup and the signal is reflected back from an empty u.fl/antenna connector destroying the LNA output on the SX1281 RF IC

    • will be ordering some parts from digikey to repair old board

  • if unable to get reliable signal link quality will use the over the counter ELRS board we have 😞
