When the motor on test 17 exploded I thought it was just an old motor. When the motor on test 18 also exploded I dug in and figured it out. These tests were the first to use a larger motor with the Mini MHD Generator. The back pressure from the restricted flow through the generator caused the motors to fail. Add another data point in MHD design.
I never knew just how a big of a bang a ‘D’ motor can make when it really lets go!
