Launches and flight results; looking for data

I am looking to gather hard data to be used in identifying the most common failure modes of sport rocket flights.

I am wondering if any clubs or sections might maintain flight card records which include flight results and whether they might be willing to share that data. The data would have to include basic rocket type (MR/LMR/HPR), or information from which type could be inferred (motor used, etc), and an identifiable failure mode for the flight; failed deployment, failed recovery system (separation), motor failure (CATO), structural failure (shred), flight path anomaly (unstable), etc.

Personal flight logs are also welcome, although confounding variable issues make statistical analysis of personal flight data more difficult than the analysis of more "random" club data.

Why do I want this data? Short term goals: a preliminary data check to identify flight failure mode categories in order to develop a useful flight information data base structure/data collection system which would promote meaningful statistical analysis of that flight data. Long term goal: an attempt to model Ballistic Hazards at organized sport rocket launches.

Loading thread data ...

I would cheerfully publish any such data/analysis permanantly.

you could start by scrounging the flight logs at EMRR.

even if you get extensive club data, you must appreciate the bias of that data: self-selected, self-reported. many people just go fly somewhere without a club, good luck getting hard info about that! I would guess most of those "failed" flights are one of: shredded/melted recovery, stuck in tree, blew away; no idea what ratios though.

I've crawled many sites already, including EMRR, to get initial database structure ideas (what info is included in a typical flight report/log). I'm interested in modeling a club launch, so club data would be applicable to that goal. A model developed in this way would not necessarily apply to any other launch environment.

This is just the first attempt at identifying the kinds of issues you mention and to see if enough applicable data even exists to justify continuing. I may have to collect the data, which is a whole other issue unto itself.

Why not send a statistcian (logger) to a large group launch? Come to mine.

Thanks for the offer. Here is my intent on this aspect of the project, although it is far down the road from this point:

I will place all original work and results from this project into the public domain.

I will ask for public domain release of any non-original data or works incorporated into the project, but will honor implicit and explicit copyrights of non-original content in any case.

Did you take the geek test? ; )

Just joking.

UKRA will have some flight logs in their web site news archive for some of the "UKRA" and K-Lob" launches. IIRC they are in both text and spreadsheet formats, though the flight outcomes tend to be free from text at the end of the record.

I'll track down the URLs if you're interested?

Darren,

Thank you for the kind offer.

I have not crawled the UKRA site yet, but will do so now. If I can't find the info, I'll blast you an e-mail, if that's okay.

No problem. You'll need to edit my email address to correct the spelling of "yahooo".
