The U.S. Office of Naval Research is getting ready to start flight trials of the Ion Tiger unmanned aircraft.
Ion Tiger uses a hydrogen-powered full cell. It’s also designed to be stealthy, with a low noise, low infrared and low radar signature, the Navy says. ONR wants to fly the vehicle this spring.
"This will really be a 'first of its kind' demonstration for a fuel cell system in a UAV application for a 24-hour endurance flight, with a five-pound payload," according to ONR Program Manager Michele Anderson.
Ion Tiger is to use a 500-watt polymer fuel cell with a high specific power system. ONR says the design employs high-pressure, lightweight hydrogen storage tanks for lower weight.
