Tonight we went from vehicle ready to wire…
To almost passing hydro test… For our operating pressure of 300 PSI the FAA minimum is 360 PSI, the sphere has a design burst of > 600 PSI, we got to some where between 350 and 370 we wanted 375 to 400. (We will never presurize in the presence of humans.)
Its clear we did not get enough penitration, the weld only went ~half way through the base metal. Very discouraging.
