Goals
Establish what to do w/r/t the icarus program post-april-12-crash
Recap
Cornflakes crashed in water
Mechanical:
Wings scrapped
(state of H frame)??
Electrical:
2 of ESCs blew up
Other 3 are corroded. Not likely salvageable
motors are damaged (at least 1
all of the power system is covered in corrosion
power module
Pixhawk
camera is damaged?
Cannot fly cornflakes or icarus this weekend
Thoughts for going forward
Clean all components, purchase new ones if we want to compete this year
probably not productive to rebuild cornflakes
Nix cornflakes
go for MVP icarus frame with vanny motors
lowest level of functionality to start off
Ground validate icarus before heading towards airtime
strap frame to table and spin it up
test autopilot
Take apart cornflakes and clean electronics
assign new members to recover these?
Cannot mess up again
lots of ground testing
next time it goes in the air must be very sure it works
video system: down to 1 camera - getting more cameras ideally? (revisit later)
Cleaning corrosion doesn’t mean we should put the waterlogged electronics on icarus
“ ESC connector issues causing a majority of our crashes.”
New equipment + figure out what needs to be fixed
need contingency on how to fix current issues like fixed wing
Put aside cornflakes get MVP for icarus
do inventory on what we do have
ground testing to confirm it wont fail for foreseeable reasons
Don’t like testing things (in the AIR) that are not yet proven on icarus
is it possible to get test airframe by next week (revisit questions later)
The costs are adding up, have to consider ending the ICARUS program if the expense grows
should go over inventory
want to fly icarus class aircraft @ comp
running out of most electronics, with barely any (~0) spares
have 1 quad motor on icarus so we have enough to run 4 assuming the ok ones on cornflakes are actually ok :|
push motor on cornflakes exists+ a small backup
can mix n match escs potentially … ($70 base cost each)
spending discussion
going smaller than vanny gets cheaper
we are way into the budget for this comp season already fact check this heeh
get 1 more set for comp
get 1 more + 1 spare set
buy 1 set of aux electronics
can borrow a pixhawk
motors 2 spares
spend minimum
run cornflakes with vanny motors last ditch scenario
need escs though. get 1 or 3/2 set of these
get 1 set we need for comp
foam destroyed on cornflakes so its ok
get some spares of what we can afford
just go for it and fly @ comp, bare minimum is ok
if we aren't confident in what we’re flying right now, no reason to be confident in what we are flying next
anticipate crashes in next flight test
this should drive our timelines
same issue every time with exception of 1 time (4 of the same loose connector)
put all the parts to icarus - buying new escs (6)
do not buy 2 sets for 2 airframes
single problem that is probably not easy to fix if we haven’t fixed it already
buy extras of escs
buy enough for spare escs and 2 spare motors
spent lots of time and money already so we want to try
have spares (at least 1 motor spare)
aux components? need to buy cameras?
spare escs
if we assume we crash next time, no point in flying at all
to continue, we have to do everything we can to make this happen - icarus should be made well
this or compete with vanny
do this properly or not at all
committing to icarus should be good if people working on it can commit to putting in the best work
assuming a crash will occur is not productive for → making icarus compete
might as well do things properly if we are going to buy new things
look @ how we replace parts on icarus - electrical failure can cause mech failures. Icarus is harder to mechanically repair than cornflakes
probably at least 1 set + a couple extras of escs
can’t keep messing these up
only commit to 1 more frame
1 spare motor
escs (enough + spares)
minimum differs on definition - min to take off and land vs compete well BVLOS
spares for things that are necessary for takeoff land
anything aux is just to do well at comp, we don’t need spares of this
should invest time in thrust testing before we take to the air so we can prevent issues we see in the past
1 set and a few extras seems fair
backup plan
need to account for case in which we crash because it may happen
spend time to mitigate this
anything on vanny is probably the last ditch
vanny reparable
can make cornflakes MVP/ ?
spend time on this instead of icarus (drop icarus for comp → run cornflakes instead?
more repairable, cheaper
less time & integ to make cornflakes MVP compared to Icarus.
All icarus components no longer re-usable.
crashing cornflakes one more time → season over GG go next WP
^ same thing applies to Icarus.
Icarus not far away from cornflakes base level?
(anni share screen instead? i need to go get food +water) gg gl atlas
@Nathan Green to send specific 2 components we need for the power module
“Options to buy:
- Nothing (no competition).
- Bare minimum (no spare).
- Bare minimum + spare.
Can be different options for each piece of equipment (e.g. auxiliary (airspeed sensor, etc.), motors, ESCs).”
should establish rigorous QA practices for all electronics.
start** flying ICARUS
one point five of ESC (7.5 → 7)
2 motor
Power Module components
no : pdb, vtx, rfd,
4 6s batteries
Week of the 14th:
anni 2 go broke
alison to make frame go brr
questions on control horns ??
anni to start laying out electronics when possible.
week of the 17th:
Anni to solder ESC’s
Nathan to be here on the weekend → PMO & Harnessing & ESC check.
Attempt ground checks on weekend of 22.
Week of the 24th:
continued ground tests.
flight test 29th? !? ?! ?! ?! ?! ?!? ?! ?! ?! ?! ?! ?! ? !? !? !? !? ?! ?! ?! ?! ?! ?! ?! ?! ?! ?! ?! ?! ?!?
