G'day Craig,
Good to hear from you. The concept of the servo pushes down on the =
diaphragm of a pressure regulator make sense to me. How it is =
constructed is something I am not too sure at this stage. However, I am =
researching and evaluating whether its a thing to do to my own project. =
After reading on the simpit forum link. I wonder how much will a normal =
regular/ exhaust valve be worth? Like yourself, I have never work with a =
servo previously, but I am slowly coming to terms with what it does :) =
Judging from the amount of PSI required to inflat the Gsuit... will =
something like a small compressor typical for airbrushing be good for =
the purpose?=20
A mate was going to give me a 50PSI air compressor (for nail gun) but =
when I told him the most I will need from a compressor is only about 10 =
PSI. He asked me what on earth am I doing with it? YOu should have seen =
the guy trying hard to understand what on earth I am trying to do :) =
Judging by your experience, it sounds like it really only need 4psi to =
do the job. So I thought something small will hopefully be cheaper and =
also quieter compared to a larger louder compressor.=20
Similar to the problem of trying to cool down my cockpit previously with =
an active cooling system. (At the moment, the canopy is not on the pit =
yet. I use a normal household rotary fan blowing air in from the =
location of the rudders) Space and noise will be an issue I have to take =
into consideration. Did I mention budget as well :)=20
Thanks for sharing your insight with us Craig.
Cheers,
Al

Hi Al,
I've been working with a couple of guys in Norway on this(I'm in US). =
We use the "shared file" in Falcon4 to get the G data. One of the other =
guys wrote a small program that runs in the background with Falcon. The =
program takes the G data and drives a servo. The servo pushes down on =
the diaphragm of a pressure regulator that controls the pressure to the =
suit.
The max pressure in high G maneuvers(real jet) is about 10 psi. The =
military uses this in simulators at about 5 psi max. I use mine at 4 psi =
max as 5 psi is starting to hurt.
I use mine more as a motion cue device than a simulation of the G-suit =
function. I've added a component to increase the speed and sensitivity =
of the exhaust part of the regulator. By having immediate response, =
changes in G feel like real motion(inertial forces).
I locate my compressor 50' away in another room. The rig makes a fair =
amount of hissing a farting; I wrap a towel around it and reduce most of =
the noise.
There's info here:

I think someone has already been using a air compressor controlled =
by a computer to inflat a Gsuit for their flight simulator?
My Gsuit is coming in on Wednesday (Thanks to Sukit from Thailand) =
and I was wondering how the setup is. What kind of computer, software =
and compressor are used and if it can be used in conjunction with falcon =
4?=20
My other concerns are the noise factor from the compressor...as well =
as the pain factor :)
Thanks in advance,
Al
