Comment on Chinese Maglev test vehicle sets world record, accelerating from 0 to 318 MPH in 2 seconds

  Only 2 seconds of horizontal g? Not unless they weren’t securely against the seat and died due to blunt force trauma from being slammed into the seat back.

    Well now we need to design the train with all seats facing forward and restraints to keep people in place, and we need to have staff abord to do do a safety check that everyone is seated and strapped in before we can get those 2 seconds of theoretically-survivable acceleration.

    Come on. This is cool from an engineering perspective but will never be used on an actual passenger train.

      That test sled doesn’t have the mass of a train car, let alone a full consist. It may very well be used on real trains, just not with such impressive results.

      Lol I was certainly not claiming this was practical, just pointing out it wouldn’t be lethal in that sense.

        It’s completely not practical.

        7Gs is also not categorically lethal hut average people will start to pass out around 4Gs if the acceleration is vertical, and 9 is about the upper limit that trained, fit Air Force pilots can experience without losing consciousness.

        So 7 is nothing to sneeze at even under ideal conditions.

    My cousin would try it, and she would bring me

  Yeah this link says most people can only take 4 to 6 g, but fighter pilots can take up to 9.

    As other commenter pointer out direction of force is important. Horizontal force is much less dangerous as it doesn’t drain your brain of blood as much as a vertical one.

      Timestamp points to drunk. I have no recollection of this thread or your comment.
