>More about the MSS-2 flight

>Chris King successfully downloaded the data from the flight computer,
Chute Controller and Featherweight Parrot. Detailed analysis of flight
data will be forthcoming in the near future.
– Ken Manatt, who led the tracking effort, provided the following post-flight report:

At this point in time, only very preliminary analysis of flight data has been performed.
Adrian Adamson has so far taken a cursory look at the Parrot data and writes:

‚The axial accel doesn’t show any sign of trouble, but the lateral accel is definitely ramping
up before the event. It’s as if there were a

sudden onset of aerodynamic instability leading to excessive angle of attack and the airframe
crumpled and burst. There was one event during the coast between burns that shows up in
both accel axes about 16 seconds into the flight.‘

Hans Olaf Toft also has taken a quick look, so far, at the Main Computer/Chute Controller data.
Of particular interest is the motor

chamber pressure data. Hans provided the following graph of the 2nd phase burn:

http://sugarshot.org/downloads/chamberpressure.gif

The burn can be seen to be nominal right up to the 20.7 second mark, when the curve
suddenly truncates followed by erratic ’noise‘. This is likely indicative of the point when
the sensor leads broke as the Recovery Bay fractured, separating the avionics from the
Booster.

A huge thank-you goes out to all those who participated in the MSS-2 launch event,
in particular, the ground/launch crew and trackers. A job well done!
