A Chopper Shield
Firing massive Kevlar and steel nets at inbound rocket-propelled grenades could save helicopters in combat
Last January, a Black Hawk helicopter flying in rural Iraq burst into flames, killing all 13 soldiers on board. A few days later, a helicopter owned by a private security company crashed in Baghdad, killing five civilian contractors. Over the next few weeks, six more aircraft were shot down, leaving 11 more dead—one of the worst series of chopper disasters since the war began.
Although the Army won’t attribute any crash solely to an RPG—insurgents typically fire guns at the craft as well—the simple, unguided, shoulder-launched projectiles are widely believed to be the primary anti-chopper ordnance of the insurgency.
New Jersey inventor Richard Glasson thinks he can stop the attacks. He’s designed the first-ever anti-RPG system for aircraft: a volley of nets that catch the grenades before they hit. Glasson was inspired by Mark Bowden’s best seller Black Hawk Down, which recounts the 1993 killing of 18 U.S. soldiers in Somalia after an RPG brought down their chopper. “I couldn’t believe that such a low-tech weapon could take down a several-million-dollar aircraft,” he says. “That’s a spectacular outcome for a 40-year-old technology.”

How it Works
When sensors on the helicopter detect an incoming rocket-propelled grenade (RPG), tubes on the chopper fire between one and eight rockets toward the incoming RPG. Each rocket deploys a Kevlar-and-steel net, which inflates like a parachute as it flies, forming an impenetrable barrier between the helicopter and the grenade.
