Congrats!

One step closer.

Hmmm... looks like it had a bit of a stability issue coming off the pad, but what was able to correct it. Any idea of the cause?

 

[CCotner]

Stability was >2cal for the duration of the flight. Not sure of the cause.

The liftoff wasn't incredibly high acceleration, and there was a ~6-ish mph breeze.

Alternatively, that could have been the keychain camera peeling off under boost. We had the camera looking forward in order to observe the deployment, but we never ended up finding it...

Did you use the aim xtra? If so what was the run time of the device in terms of downloading the data off the device ? Less than 3 min? Have you tried downloading any data off the device after exceeding one hour of run time which I would assume your device would run that long, if not longer for the actual flight ??

No, we didn't test it on this flight.

The flight duration won't be that long, you know. It'll fall pretty darn fast in the upper atmosphere, and hopefully intelligently stop data recording upon hitting the ground. (I haven't read the manual myself so I'm not sure)

 

[gtm3323]

thanks carlo - youre right, as always. after looking over the data and settings more closely - the data stops writing once it lands. be advised the aim xtra should be doing a software update in the next several hours after I noticed there were some bugs in the software settings that was creating issues for downloading the data. also there isnt much to the manual more is leared just navigating through the software. t minus 14 hours until I start heading up to black rock.

We just measured the mass of the components of the rocket: total weight 41.07 pounds; dry mass of 8.38 pounds.

Our more conservative estimate of apogee from RASAero: 99,599 feet at 73.3 seconds. This was had by halving the lengths of the fin bevels and adjusting the dimensions of the fincan.

If we put in the actual dimensions, though, we get 115,569 feet. Pretty intense!

Are you guys here yet? I think we are doing the group picture first thing when the range head opens, since Judy and Gerald are probably flying tomorrow.

This is amazing!

I am excited to see your results and the data from this flight. Good luck! May the skies be clear.

No, we are leaving first thing in the morning tomorrow.

Safe travels. Looking forward to hearing the results of the flight.

 

[mannyskid]

I met with Chris and Carlo at the site just as I was about to leave to go back to the hotel. I took a look at their rocket and with a little prep work it will be ready to go. Tomorrow morning should see four minimum diameter full N motors hit the ground, I can't wait!

They came, they flew, they....well, on the way up, there was....a problem...down was...faster than planned...

[WillMarchant]

Bummer! Faster than gravity?

 

[MasonH]

Well...

So mysterious....

It is a lot harder than it looks.

This have anything to do with that wiggle off the tower on their test flight?

 

[Coop]

Awww.... shucks. So sorry to hear this.



Later!

[troj]

No idea. Midway through the burn, it had a definite wiggle. What happened, I don't know, and I don't want to speculate as I have nowhere near enough data.

I'm hearing they got everything back, and in good condition. Nothing more than that.

[Eat, sleep, and Fly]

Darn... I really thought that they would pull this off. Was it, perhaps... a dreaded CATO? I know they said that they had to force the liner into the case. To bad

 

[REK]

I hope there is video footage to watch later. I am curious to see how fast it ripped off the pad.

Here is the crappy video that I took.

[REK]

looks good to me, man that thing was hauling arse. They were so close.

 

[Eat, sleep, and Fly]

Hmmmm... definitely not fin failure. The failure analysis should be interesting.

 

[BLKKROW]

Hmmmm... definitely not fin failure. The failure analysis should be interesting.

I am guessing either the nosecone or the coupler between the case and nosecone.

 

[REK]

I am waiting for them to post the results and some pictures hopefully. I was curious and I wanted to see what would happen if the nose cone was lost and to my surprise this rocket would still be stable. I assume if the nose cone did come off, the shock cords yanked on the rocket as it tried to continue its path upwards. Its just a thought.

 

[Eat, sleep, and Fly]

My best guess ( based purely on speculation), is that the failure occurred at the joint between the motor case, and upper body tube. If that is the case, the booster very well may have coasted to a normal apogee. Either way, Chris and Carlos should be very proud of themselves. They thought over every 1000th of an inch of this project, and I truly hope they have the opportunity to try again. I am sure that money is tight, having both just graduated college, but down the road a bit maybe. I think this was a fantastic project, and a very valid attempt. :clap:
