Taken during the day live by @Daniel Puratich
Task 1 Toronto
Fine downwind
Bad oscillation on upwind only
Got worse as battery went down
Smart batt system to detect this?
BMS system
Crashed at upwind of third lap
Decent to alpha, went horz then vert to it
Protective shroud around motor
Clear sharpie thing on the arms for direction and number
Tilted landing gear helps absorb shock
All planes without hydraulics do it
Little bend makes things easier
Evan and Smjle agree, need them to fight in future
Guelph
Depopulated quad motors
Flying fixed wing only
Random idea we got from takeoff
We shoulda thought of making an rc car put a few props, fly up to alpha then back to ground then drive back and forth for a while, way more power effective and far easier, hack would work for task 2 as well. Waaay better idea than the blimp lmao.
No laps, no waypoint alpha but they took off in fixed wing flew and landed correctly
No quad props/motors were mounted but presumably they will for task 2
All manual flight
Sherbrooke
Removed wings from vtol
Quad only
42 sec hover
Didnt get high enough for alpha
Went for one lap at low altitude
Crashed far away near bravo
Unknown cause
Project Managers
PMs should have same level of ownership as leads?
Leads are admin managers
Pm are project managers
project managers shoulf work accross subteams Mostly
Rarely should projects only be within subteams
Ask other teams on what they do
Efs doesnt have online tasks
Autonomy needs integrstion
Think tracking ant issue, sims work, but we need reality
Alberta
Quad
Tilted was done for efficiency but they didnt communicate it to airframe team so they didnt tilt the cabin properly
10 dwgree tilt is ideal
1min to alpha
Told us it was set to 5 up and 10 over
Landed after alpha
Fully autonomous
UBC
Vtol, wings fitted, motors fitted
Went up in 40 seconds
Looked good on ascent to 100m straight up in quad
Then transition went well
Then somehow tried to detransition before alpha
Lots of instability
Small xrash landing at takeoff location
Might fly again? I left for lunch
They flew again, same issue, getting tossed around by wind
Tried to go forward again on a third attempt, no luck
Possible voltage sag on batteries when they try to transjtjon.
More thoughts
Nathan wants vtol if he can convince people
Push him to outline the longer program of fixed wing to vtol while maintainning peggy as backbone for competition.
We arent short on funding, need to spend deliberately. Tong is on the rest of the MEF we need to blow this term.
Carleton
Lots of time working on drone in window
We heard a little pop 30 mins in
Walking out with 10 mins left
Prop seems too close to cabin at back
Vtol, wings are on
Up and down 40 second flight
Basic controls check
looks good in hover
Quick battery swap?
Drone roughly 15kg
Similar motors we had last year
5 mins remain
Straight up
30 sec in transitiom
Alpha at 40
Roughly 45 seconds is more accurate
stopped at alpha, u turn then transitionned again
ran out of time, didnt go to bravo
team on line has no controller, likely auto
Was pre fast when fixed wing
Didnt get a lap but made it to alpha
landing is pre nice
they use wifi, coulda been a rf issue that forced rhem to turn around
Comms or time limit forced them tk turn arkund before bravo
Takeoff again, seems like their flight time should be over schedule wise but if they got barbies late then this is ok
48 second from alpha to bravo roughly
Crashed near bravo
ETS
Queens
Waterloo

ETS
Quad
Big motors and props, battery looks small
Did compass calibration on ground
Took off
Hoverred for a while
Ascended pretty hard, lots of power
Compass variance?
ascended to ceiling? Looks like above 400m, judges asking them to descend
did a lot of bouncing around, but when simply descending it looks stable
large motors disturbing compass when theu change throttle
put it down in the grass behind tarmac
Judges asked them to land when they were high up
Low wind
Flight was a few minutes
Did not reach waypoint alpha
Sat on runway for a while then gave up
Queens
In air on hover
Wings depopulated
Vtol style aircraft
Mid portion of wing still fitted
first flight is a control check, looked good, hovers nicely, landed aftrr a minute or two, did not ascend
They mounted an antenna on their pusher prop lol
Another takeoff, also controls check
Waterloo
did u of t get counted for their two laps?
If we get a single lap is that full points?
Confirmed counted
See debrief document, all went well, still need to ask task 2 questions
