Highlights of recent developments on the MiniSShot Project
-------------------------------------------------------------
- Alberto Gassol has updated the Sugar Shot website documentation page
with three additional MiniSShot documents.

- A experimental setup has been devised which will test the hypothesis
that the anomaly that occurred at the start of the 2nd phase burn was
caused by grain fracture or disbonding of the propellant from the
casting tube. If the chamber pressurization had been too rapid, and not
provided enough time for combustion gases to flow around the grain
assembly (to equalize pressure), then unplanned structural loading of
the grain would have resulted. This could have been a consequence of a
number of factors, including too powerful an igniter charge, the
additional primer that was applied to the grain core, or the reduced
spacing between the grain assembly and the casing (in comparison to the
successful July 2009 motor test firing).
The test setup is illustrated here:

Rick Maschek has agreed to head up the test. Both Nathan Asdourian and
Paul Avery have volunteered to help out with performing this procedure.
- On Saturday, Rick Maschek gave an SS2S presentation to engineering
students at the University of California at Santa Barbara. The
presentation was well received.
