Study Of Helmets With Face Shields

Study Of Helmets With Face Shields.
Adding mush shields to soldiers' helmets could condense brain damage resulting from explosions, which account for more than half of all combat-related injuries prolonged by US troops, a new study suggests. Using computer models to simulate battlefield blasts and their junk on brain tissue, researchers learned that the face is the pipeline pathway through which an explosion's pressure waves reach the brain. According to the US Department of Defense, about 130000 US repair members deployed in Afghanistan and Iraq have sustained blast-induced distressing brain injury (TBI) from explosions.

The addition of a face shield made with transparent armor corporeal to the advanced combat helmets (ACH) worn by most troops significantly impeded direct bellow waves to the face, mitigating brain injury, said lead researcher Raul Radovitzky, an allied professor at the Massachusetts Institute of Technology (MIT). "We tried to assess the physics of the problem, but also the biological and clinical responses, and tie down it all together," said Radovitzky, who is also associate commandant of MIT's Institute for Soldier Nanotechnologies. "The key thing from our point of view is that we truism the problem in the news and thought maybe we could make a contribution".

Researching the issue, Radovitzky created computer models by collaborating with David Moore, a neurologist at the Defense and Veterans Brain Injury Center at Walter Reed Army Medical Center in Washington, DC Moore Euphemistic pre-owned MRI scans to simulate features of the brain, and the two scientists compared how the mastermind would retort to a frontal denounce wave in three scenarios: a head with no helmet, a head wearing the ACH, and a headmaster wearing the ACH plus a face shield. The sophisticated computer models were able to put together the force of blast waves with skull features such as the sinuses, cerebrospinal fluid, and the layers of gray and bloodless matter in the brain. Results revealed that without the face shield, the ACH slightly delayed the gale wave's arrival but did not significantly lessen its effect on brain tissue. Adding a face shield, however, considerably reduced forces on the brain.
