We’ve started building the shell for the crew module mock up. The shell is make of one inch foam to be skinned with kraft paper. To get the foam to bend how we want we drilled it full of holes. The side walls are make from six large sheets. We calculated that we drilled just over 1,400 holes on Saturday.
The question that comes to my mind is whether the increased flexibility in the foam from the addition of the holes is offset by the decrease in rigidity?
