Study Of Helmets With Face Shields

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

The addition of a face shield made with transparent armor resources to the advanced combat helmets (ACH) worn by most troops significantly impeded direct denounce waves to the face, mitigating brain injury, said lead researcher Raul Radovitzky, an subsidiary 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 sleeper it all together," said Radovitzky, who is also associate impresario of MIT's Institute for Soldier Nanotechnologies. "The key thing from our point of view is that we commonplace 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 cast-off MRI scans to simulate features of the brain, and the two scientists compared how the intellectual would rejoin to a frontal detonation wave in three scenarios: a head with no helmet, a head wearing the ACH, and a culmination wearing the ACH plus a face shield. The sophisticated computer models were able to coalesce the force of blast waves with skull features such as the sinuses, cerebrospinal fluid, and the layers of gray and ghostly 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.
