Wings - Nathaniel
Prototype mini-wing successfully made
Increased overall size of ribs by 50% to accommodate components like servos (chord length up from 0.23m to 0.345m)
Flight characteristics would be roughly what we expected but with more lift and drag due to a larger wing area
4kg is everything with batteries (including wings) but no tail.
Aileron holding back CAD from being finalized
Planning to make it out of 3d prints since assembling and wrapping small aileron sections will be challenging (and potentially heavier)
CAD for mounts is WIP
Mass of the frame + wings with NO empennage, servos and electronics (except Pixhawk) is about 4 kg.
Plan to route wires through the wing tubes.
Single Servo Driver End User Manual
@Meghan Dang to add dimension information here.
31mm x 18mm
Possible to mount the servo driver for the aileron servo at the center plate?
Small enough to be taped onto the servo
3D printing all control surfaces (aileron, rudder, elevator)
Manufacturing material order to be placed this week. Manufacturing will officially begin next week
2024-11-06 Eclipse CAD review - Meetings - WARG ← CAD review if interested
Avionics
Single Servo Driver CAN
three boards have power that functions and all rails come up
bucks work well, step loads, inrush testing, load testing passed
firmware works on Nucleo needs to be ported and tested
remaining POR for maiden
work into assigning, https://app.asana.com/0/1208217874711985/1208381323116503
6S Servo Module CAN
Ordering on Monday, partially assembled
Pinout updated, buck layout done, more layout to finish
likely blocked by same issue as above
remaining POR for maiden
6S Power Module CAN
Buck is tested, powers up, works in CCM and DCM
more validation
not firmware focused
not POR for first flight of eclipse next term.
What sensors do we have?
@Nathan Green to srtart purchase thread here for thsi
need to order: Pitot Tubes, compass, pixhawk
2x CAN GPS we have
have VTX, unsure on camera
Timeline
Manufacturing and ground testing timeline thoughts?
Starting next week. Frame could be done by end of November
Nathaniel - Wings can most likely be manufactured by end of November
Same as what we’ve already wise
Piloting
@Manasva Katyal not here.
@Jerry Tian after exams will start on foam plane stuff
@Kenny Na will have baord for pwm receiver and power by then.
