DRDC Centrifuge - High G Tolerance Tests

Aug. 27 2009

  • I had the great opportunity to go for a spin in the DRDC (Defense Research and Development Canada) human centrifuge.
  •  
  • Although I have been in a centrifuge before, this one brought me up 5 G's in the Z axis head to toe), previously, I had done about 3.5 G's. To keep from blacking out and experiencing G-Loc, I had to learn very specific and strenuous muscle flexing and breathing techniques that help to keep the blood flowing to my brain and heart. Assisting me with these efforts was a Canadian designed G-suit which is basically a pair of pants with air bladders that are hooked into a compressed air system and automatically inflate at high G. This helps to squeeze your legs and push the blood back up where you need it the most.
  •  
  • The experience was very intense and I can't imagine how a fighter pilot could actually operate a jet under those extreme conditions. I was hoping to try for higher G forces but the base doctor was worried about my retinas detaching.

    A wider look at the blender, uh, I mean centrifuge.
