Launch 4 Gyroscope results

Below is a graph of the gyroscope results for nearly 8 seconds of flight.

Rotation of rocket during flight (up until Apogee)
Rotation of rocket during flight (up until Apogee)

We can make a few statements about this plot.

  • The rotation was anti-clockwise along y-axis (up) when looking up.
  • The rotation sped up until about 1.5 seconds (until the motorĀ stopped running)
  • The whole rocket started to lean over in its flight at about 6 seconds, which is the approximate time required to get to Apogee. (We had our ejection charge to ignite at 6 seconds).

I have a feeling that ejection probably occured later then what I wanted, even though it was supposed to happen at ~6 seconds. I say this because I would have expected a bit of a spike in data as the rocket gets ‘kicked’ around a bit during ejection.

This is suspicion is supported by the video taken by the on-board video. There is a sudden loud sound and jolt from the camera at ~9 to 10 seconds after launch. This would be approximately 1.5 to 2 seconds after the data points above.

So this is very interesting and helpful for future work!
