Cooper Yeah, when you are sealed up in it it gives
you about a half a psi in pressure in there
which doesn't decrease your mobility a
great deal over what the regular suit does .
Temperature in the suit, I certainly
can't complain there. I had to sort of
eat crow on that . That suit circuit ran
consistently. We had to really shut it
completely down to get above 55 degrees
t emperature on the suit heat exchanger
outlet and generally it ran around 50 degrees
which just froze my rear off and I had my
suit flow . . the general configuration we
had was both of us f".ad the suit flow
rates quite a bit back . I had mine clear
back to almost a minimum position and we
had the suit coolant loop shut down to
where it was just about a half to one notch
open from the fully OFF position. I really
got quite concerned that they were going to
freeze us to death. In fact one whole night
side I had my suit inlet exhaust hoses off
and laying down alongside the seat because
e ~ as iust too cold in the suit . Humidiv.
