[simpits-tech] ACES II Replica, G- cueing Seat.

[Craig Rochester]

Hi Chris,

I've been reading through the archives and found your posts on the G- Cueing
seat.
I've been working on a G-Suit pneumatic rig with some guys from Norway.  See
this forum
thread:http://www.simpits.org/forums/viewtopic.php?topicU&forum=1&start
<http://www.simpits.org/forums/viewtopic.php?topic=55&forum=1&start=15>  (go
to bottom).  I worked and worked to get a "regulator" that would exhaust
quickly.  I finally stumbled on a rig that works well.  I use a "quick
exhaust valve(QEV)" and a high capacity regulator.  The air exhaust is as
fast as the supply.  Qualitative guestimates on performance:
Range of supply pressure = 0-5 psig
G-Force vs. G-Suit pressure- 1-9 G = 0-5 psig
9 G - 8 G(5-4.5 psig) decrease take about 0.1 sec
2 G - 1 G(0.5-0.0 psig) decrease take about 0.2 sec
9 G - 1 G(5-0.0 psig) decrease take about 0.75 sec

The bottom line for me is the feel of the G-Suit.  I can feel 1/4 psi
changes, and the changes feel intuitively correct when I fly Falcon4.  But
I'm not a pilot and have never pulled Gs.;)
Do you have specs for the G-Seat latency requirements?

Craig
