  • Letting the Ion Tiger Loose
    Posted by Robert Wall 7:24 AM on Apr 01, 2009

    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.

    blog post photo "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.

    Here’s an ONR video:
