Military Helmet Design Contributes To Brain Damage
BuzzSkyline writes "Improvements in helmets have helped modern soldiers survive bullets and blasts that would have killed them in past wars. But increasing numbers of soldiers are suffering long lasting brain damage from explosions, partly as a result of what appears to be a flaw in helmet designs. Although the blast itself may not accelerate the brain inside a soldier's head enough to cause injury, shockwaves that make it through the space between a helmet and a soldier's head can cause the skull to flex, leading to ripples in the skull that can create damaging pressures in the brain. Simulations that relied on 'code originally designed to simulate how a detonated weapon rattles a building or tank' could lead to new helmets that reduce the traumatic brain injuries that many soldiers suffer as a result of improvised explosive devices and other moderate-sized blasts. The research is due to be published in Physical Review Letters, but a pre-print of the entire article is currently available on the Physics ArXiv."
I tought helmets were designed to protect from debri and flying objects caused by explosions, not the shockwave from 2 pounds of C-4 lying around.
I was underweight for my height (5'10" / 115 lbs). After spending 6 months trying to gain weight, was able to get a waver and go in to basic. 4 years later, had managed to gain 12 lbs. Out on the flight line, they called me Stickman. I was able to get in through small access holes (KC-135's) and fix stuff that would have taken an extra hour of work to remove larger pieces of skin. Got a decent amount of free booze for helping speed up repairs.
