G force simulator

[screamingdemon]

Was wondering if a device like this could be made?

 

Two methods I imagine could work:

 

a) Inflatable straps that wrap around body parts - similar to the device used to squeeze your arm when you have blood pressure measured. Air could flow in and out based on Gs being pulled.

 

b) Install harnesses on you favorite flight sim chair. Straps tighten and loosens based on G force. Either electric motor or a pneumatic cylinder that could be activated to cause tension.

 

Hope these   ideas inspire someone to make it. I will be first customer   :russian_ru:

I don't think you can make this by tightening your blood vessels, and Im not sure it would feel anything like g-forces. The main feeling of gforce is extreme heavyness and a gut feeling, the only way to simulate that somehow is in a centrifuge. I thought about that too for a while but i guess gforce is just not simulateable in a home setup.

 

b) Install harnesses on you favorite flight sim chair. Straps tighten and loosens based on G force. Either electric motor or a pneumatic cylinder that could be activated to cause tension.

 

This sounds like a brilliant way to die.. Straps get pulled, motor fails and you get no more air through your lungs. :o

For sure it is not intended to be trying to replicate a real G force. The idea is only to create a discomfort that simulates the effects. It will also add an immersion that will make you feel the strain that the plane is going though. It will enhance the "seat of pants"   flying experience I do believe.

u need a chair that when you snap 10G pull in those La5 it drops a 1T Anvil on your lap

So yesterday I was driving with my friend in his Mercedes. I noticed that when you hook up the seat belt, it automatically tensions up the slack. When it senses a certain tension it automatically releases just enough to allow free movement.

 

This would be the ideal mechanism for this hardware. Any technical guys out there who could be inspired to make this work?

G simulation for fighters has been tried for a long time in military sims - my first experience was with the old ACES sim at Luke AFB back in the 80s that had modified G-suits (no exit valve so they wouldn't stay inflated) and a compressor linked to the G's being pulled.  Had to be really careful to have the g-suit really loose or you could really mess up your blood pressure when flying the F-16! The ACES sim was an early full dome fighter sim with two cockpits (F-15A or F-16A) - lots of fun even if the graphics were terrible.  As far as the G-suit; I though it was pretty good because you could tell your energy state without looking at the HUD - if you pulled and nothing happened, you were slow! But you had to have a lot of previous experience with real G-suits for it to transfer, in my opinion.  And most guys didn't bother with it...

 

More recently, I worked on the M-346 sim for the Singapore AF - it has a g-seat (inflating/deflating seat cushion, tightening straps), g-suit (similar to the ACES system), simulated oxygen pressure breathing system, and a pretty good hi-res dome system with excellent graphics.  When you wore all your kit (helmet, g-suit, gloves) and all worked it was...not very convincing, as far as Gs. The g-seat was a waste of time, IMO, and again the G-suit worked by reminding you that you should be in pain - but only if you knew what to expect.

 

Most high-end fighter sims I've flown don't even bother - at most you might get the blackout cues visually but that is about it.

 

I've also done the g centrifuge thing - OW! Not fun, although we would get into competitive g-pulling contests - the ride ended (after working up to 9 gs) with a simple gun track exercise, and if you got wrapped up in it you could forget to breathe and then you pulled just a bit too much trying to get the pipper on the Mig and ZZZZZZZZ. Talk about waking up confused! And all this shown live to your buds up in the control room.  This was back when the centrifuges first came into use (mid 80s) and a lot of us still smoke and partied - it was fun watching the marathon runners in the squadron pass out at 7 Gs while those of us who preferred 12 oz curls while smoking a Lucky could go right to 9 Gs pretty easily (I think my resting G was 6, 7 was easy with just a g-suit, but 9 took work!). Worse thing about the centrifuge was getting out - since you had been spinning in a pretty tight circle your inner ears were really pissed off and it was really hard to walk without falling over (more amusement for your buds watching while waiting for their turn).

 

Watch out for the short fat fighter pilot in a knife fight!

How about a suit with internal chambers, which would be filled/emptied with water by a pump, depending on current G?

 

You would be literally "heavier" without any unwelcome changes to blood pressure.

there is a full chair cushion that fits the seat and back that fills with air to a predetermined level, it will inflate or deflate with movement of the simulation, it deflates to simulate sinking into the seat under Gs, and inflates for the opposite, but it also has two chambers, left and right to simulate movement in turns....... add a buttkicker for vibration and yer set............................
