G-Force, Jerk, and Passing Out In A Centrifuge

  • Thanks to the Starrship team for arranging this! I'm also over on their channel, flying with the Blades: tvclip.biz/video/iWY3-1gOrxk/video.html • At the Royal Air Force training centrifuge in Farnbrough, pilots learn how to avoid G-LOC: g-induced loss of consciousness. Let's talk about g-force, about jerk, and about how to keep circulation flowing to your brain.
    FAQs:
    * Isn't 3.6g a really low g-tolerance? *
    Yep. Turns out I would not qualify to be a fighter pilot. The average range for g-tolerance is 4-6; no-one was expecting me to pass out. The centrifuge team do not deliberately try to G-LOC people! To be fair, though, I'd done a few earlier runs with only minor effects.
    * What g was the RAF person at the start pulling? *
    That's Marcus, from the Starrship team, and he was successfully pulling 6.5g with the help of g-trousers: they plug into a compressed air source in the plane (and in the centrifuge) and act as a lower-body tourniquet to keep the blood up top. They are very effective.
    * Why did you shake and shudder when regaining consciousness? *
    Those are called "myoclonic convulsions", which is a fancy medical term for "muscle jerks", and they're a common side effect of recovering from G-LOC.
    * What did it feel like? *
    I'll answer this in more detail in a video over on the Matt and Tom channel soon, but in short: I don't remember it. I was doing the breathing maneuver, then everything was wobbly, then we were stopped!
    * Is this a sponsored video? *
    No: the RAF and Starrship had no editorial control over this, and no money changed hands. Obviously, though, they gave me a spin in the centrifuge, and I'm collaborating with them over on their channel too!

    If you have questions (what did it feel like? why did you convulse? isn't 3.6g a really low tolerance?) pull down the description, I've answered a few there! And if you see someone ask a question that's in the description, please point them there.

      THERE IS NO CENTRIPETAL FORCE. If there is a force you should feel it. The people in orbiting(circling) frame will feel the force. Observer do not feel that force. But thinking everything circling...even if you attach pendulum...it will hang there. There is a fight between gravity and centrifugal force. higher speed it will match the circle. if it string gets cuts it will be thrown out. it shows that there is centrifugal force.

    And I think I know everything... Thank you. I didnt think or know about rate of acceleration as a factor and that untill you try it you do not know your tolerence. 3.6? I dont know about extreme theme park rides. Id guess 2.5. 3.6 is good enough for me! I beleive a RCAF pilot can do 7g and sees B/W with complete suit, on the edge with 3 years training. Fair enough! Kuddos!

    There’s roller coasters at Magic Mountain here in Los Angeles that easily go over 4-5 Gs. Are you telling me this dude would pass out on Revolution? The weakest ride there. BLIMEY! 😂

    • User100
      User100 Month ago

      No rollercoaster sustains 4-5G for any sort of reasonable time, not even close. It's very very periodically, that's why loops are tear drop shaped. The only rollercoasters with high G and somewhat sustained are ones with perfectly circular loops, but those aren't common because of how much G you pull. There's also a massive difference between horizontal and vertical G force when it comes to affect on your body.
      On launch roller coasters it's horizontal that makes it a little difficult to breath, but it's the vertical G that will black out most people, but even then on launch coasters that go up 90 degrees after launch (like Kingda Ka at Great Adventure) it's only for a fraction of a second at maybe 4/ 4.5 G
