Another factor to be considered regarding being able to pull 10G without a G suit is the pilots position. In these types of aircraft the pilot is almost laying down which considerably increases the pilots G tolerance.

....adjusting spectacles......The whole theory behind the liquid-filled g-suit is, basically, taking a leaf out of nature's book. No other insect can pull as much g as the Dragonfly, I think, which makes sense because they are pretty impressive to watch changing direction. The Dragonfly can do this because it's organs are surrounded by a fluid barrier......I don't understand the physics behind it.....no accolade to physics as I don't quite understand why, in a falling lift, if you just jump up before it hits the ground you won't be ok!!!! Anyway, it just works. Some smart swiss fella, intrigued by this, has designed a g-suit called the 'Libelle' (translates as Dragonfly) which uses the same principles. Have a GAF mukka that has tried it and 10g without straining is apparently no issues!
Damn smart these Teutons......

We were trials guinea pigs for the liquid-cooled suit for the Tornado some 10 years before it entered service. Unlike the air ventilated suit the LCS was in close contact with the body. This meant that the coolant had to be circulating on the ground to avoid heat stress. We had to carry a liquid ice refrigeration pack, just like the Astronauts, but it made a pre-flight walk around much more difficult.
Had we bailed out the first thing on landing would have been to strip the suit off. It was not proceeded with but it may have found a use in glass furnaces.
I have heard and seen developments in the technology and idea which is to also use the liquid or ‘hydraulic fluid’ as a cooling agent for the pilot’s body.

liquid cooled body suit
Might be a big improvement, when suitably developed, for NBC / immersion suit conditions ?
Also the last I heard ( out of the business a while now ) the Rafale & Typhoon were thinking of at least 2-stage 'reclining' seats for G tolerance versus seeing more than one's toes the rest of the time.

The reclined seat idea is great for a turning fight at sustained G, but for day to day flying it puts a lot of pressure on the neck as you sit in a craned position looking at the MFDs. I know of at least one F16 operator which uses chiropractors and physios on each squadron to counter these issues.

Raymond,
Wise words ref the water-filled lift. There must be a niche market there! Probably need fatter cables to take the extra weight.........and, I suppose, there will then be a need for wellies should the worst happen....another open market.....right that's it, I'm off to seek funding!
Still trying to figure out the real head-scratcher, though......why, when you put a pair of socks in the wash only 1 comes out. Must be some cunning sock filter or something....or maybe, being smaller items of attire they don't quite fall into Newtonian physics and, in fact, are subject to the vagaries of Quantum Physics? Maybe a mixture? Maybe, just maybe, the vanishing sock mystery, on investigation, will yield a Grand Unified Theory? And if this is so, we could then travel faster than light....which would require a F*ck*ng brilliant G-suit than can keep us conscious up to infinite g. Yet another market to exploit! And, you see, a very tenuous link to this thread! We need to make sure that our weapons technology advances at the same pace though because we wouldn't want to be at the stage that Captain Kirk & Co are at with really slow Photon Torpedoes that get suckered by chaffing a crisp packet or the Millenium Falcon's awesome laser targeting system (they stole that from WW2). The mind boggles. Phew....knackered now!

That water-filled g-suit would be keen, especially if it didn't expand like the air-filled one. I can't count the amount of times the g's would come on, the suit would inflate and the kneeboard would blow off to an unreachable part of the cockpit.

)Next thing and you would have been solving the eternal advice given to guys too smart for their own good: Go F**k Yourself!
From the research I did on G-Loc in the 1980s (when things like Combat Edge were being developed) the biggest factor was onset rate, although max g and time-at-g were related issues. That's why the solutions that were applied included faster-reacting valves. However, since the name of the game was to keep the brain oxygenated and full of blood, other measures included more lower-garment coverage, to squish more blood out of your a**e to where it does some good consciousness-wise, and positive pressure breathing. (Combat Edge, F-22 and Typhoon - which also accounts for the 60K-plus service ceilings on the F-22 and Typhoon.)
I think the German Typhoon pilots are still using the Autoflug Libelle suit. This is a major update of the WW2-and-later work on water-filled suits. The fluid (same density as blood) is contained in flexible pockets that run through the garment, which is made of a material that won't stretch. Under g, the fluid flows down and the suit compresses the body from the ankles up. It was advertised as being more comfortable and more effective (more coverage, reaction exactly proportional to g and faster than air inflation). Why it has not been more widely adopted, I don't know, but there may be disadvantages as well.

Gripen crash - g-suit blamed.
How did that happen?
