Pictures / Data from Flight 17 Lachlan
We lost part of our payload. This flight used a 1200 gram balloon, launched from my cabin in Carbon. we had 2 aprs tracker and 1 spot. Tracking worked out well on spot and aprs tracker, 1 tracker failed due to separation, Go-pro, datalogger and rtrack were separated from the chute and is currently lost . We made it to 80,000 ft.
There is still a chance someone will find it and call you.
Here are the problems that happend:
- we had issues last night with the cutdown, i think my radio is sending the cutdown commands on startup if there was no reciept in memory. Something to watch out for in
the future. Wasn't an issue today, but could have been.
- the balloon burst really earily along the crease, I wonder if this balloon was expired or so?
- we almost had a separation of the payload on launch, due to knots, perhaps we should as a team review good knotts, I know my knotts aren't very good as well. This can
happen to any of us.
- We had a payload separation due to failure of a zip tie loop, I recomend either tying together the lines or using metal rings in the future.
- Finally we had shutdown of one of the trackers, I have a couple of thoughts on why this happened:
) It's possible it hit the ground and failed, however i can't image it went from 60,000ft to 2000ft in 1minute
during separation, the antenna could have touched each other, thus grounding out the signal on the way down, This might be due to the antenna lines so close together,
during my antenna testing if the antennas get close to each other, range is affected significantly.
did you notice that the tracking was lost during a wind direction change? perhaps the tubulance between the 2 systems broke it? see map in pics below.
I Still can't believe we landed on the road again.
