I just wanted to check and see if there was any wrasp data (or similar) for an AT K1100 from 2005. I see the data on Thrustcurve.org is from 2006, which is pretty similar, but I also see that the original summary data listed on thrustcurve calls it a 14%K while the data files are closer to a 25%K.
We had a flight this weekend that was about 25% low in altitude (1350 vs 1700ft) and I wanted to try and find the source for the error in simulation vs actual. The motor lit instantly, so I believe it was in good shape and we re-weighed the components to make sure we didn't mess that up, but so far, things look OK. The flight profile was pretty vertical and to lose that much altitude would have been obviously non-vertical (40 deg approx).
I do have data from my Raven, but I've never figured out how to generate motor parameters from the flight data. If that will be helpful, I can attach that. The rocket weight without motor was 27.7#.
Any help on locating an older thrust curve or other suggestions would be appreciated.
Thanks!
Sandy.
