PAC3 magnetic data, Flight 5

I added a Honeywell HMC2003 three axis magnetic sensor to the RDAS to collect data on the rockets attitude. From top to bottom, the traces in the plot are acceleration, lateral axis one, lateral axis two, and longitudinal axis. The periodic blips in the data are caused by the RDAS piezo buzzer. The effect is not magnetic, it is from the current pulled by the buzzer causing the battery voltage to sag a bit.

There is a very noticeable effect from the launch rail at the beginning. The rail was a BlackSky rail made from aluminum but it was reinforced with a length of pipe.

The longitudinal axis sensor shows that the rocket had pitched over considerably before the parachutes were deployed. This matches my visual observations as the rocket appeared to be laid out horizontally at deployment. At the time of launch the wind was blowing at about 10 to 15 mph. In spite of the wind and very low launch velocity the rocket was once again very stable and flew perfectly straight up.

Although this flight was very interesting in that it was close enough that everyone could see everything that happened, I don't care to repeat it. For such a large and heavy rocket it was much too low and slow for me.
