Hi Chris, Thanks for the mail. I opened the Cranfield Aerospace site, =
what a fascinating outfit, UAVs as well.
Trouble is since seeing your joint seat nothing else will do.I doubt =
mortgaging the house would get me one.
Seriously thats a beautiful bit of work and it seems to do everything we =
would ever need. Obviously Cranfield have put a lot of time and money =
into this development and are not going to give much away.
Most of us use our Sims in a home environment and hydraulic oils are =
simply too dangerous to have inside a living area let alone to be =
injected through your skin. The only ways to go are electrical or =
pneumatic.
It looked like the VRF Corp Tactile Feedback System might be an =
affordable option, combined with some other effects. I placed an order =
with them about a year ago, but since an e-mail last December saying =
they were ready to ship, nothing.
Sounds like a great job you have, that Bae Jetstream is a lovely =
aircraft.
Meanwhile back to the drawing board after seeing the bloody Holy Grail =
of seats.
Best regards, Brian West.

HI Brian,
=20
I did some intital research on the web and found some items, Ill =
have to look them up. Most of what cranfeild has they keep close to =
their vest ( expensive proprietary research gave them thier algorythims)
I have a non- Discloseure signed with them.
They do have a website: www.cranfieldaerospace.com
=20
I really enjoyed their place last month. I got to go on a test =
flight in a fully instrumented Bae Jestream and did some wild flying in =
it while getting to read the instruments.
They also have a full up 747 simulator with wide view visuals. Lots =
of toys there!
=20
The 1800 psi was in reference to the older hydralic systems for G =
cueing....I agree with your terror in that!
IF 1800 psi line sprang a leak near you it would shoot hot high =
pressure toxic hydralic fluid into your body like a hot knife thru =
butter...not to mention hydralic things always leak. I spend way to much =
time making my cockpits look nice to introduce that crap into them!
=20
I do know that the vertical axis must be capable of at least 40 hz ( =
fairly high performance for an actuator)
=20
I would love to hear how your system turns out!
Just for reference, before I came along to cranfield, their systems =
cost well in excess of six figures...I gave them a lower cost option =
from buying a real ejection seat. They either got real ones or bought =
expensive replicas from a UK company ( NO MORE)
=20
I forgot to send home a picture of my replica line of seats. I will =
try to do so tommorow. I had a very hectic day at work today!

CHeers,

Hi Chris, Many thanks for your detailed and thought provoking =
run down. It gives me quite a bit to ponder on.
Do you happen to know if Cranfield Aerospace put out any =
technical literature or have you come across any published research?
The system I have in mind is a closed loop with positive =
evacuation of each bladder using around 25psi. The thought of 1800psi =
made me involuntarily cross my legs. =20
Best regards, Brian West.
