AEROPAK, a next-generation fuel cell power system recently developed by Horizon Fuel Cell Technologies will increase the flight endurance of small and stealthy electric unmanned aerial systems (UAS) by as much as 300 percent. The fuel cell technological advancements will bring significant enhancements to UAS, making them more effective in persistent intelligence, surveillance and reconnaissance (ISR) missions, a main focus area for leading defense and security organizations around the world.

Rolls-Royce: Open rotor 'is real'; Pratt pushes geared turbofan
Rolls-Royce expressed confidence this week that the open rotor concept can be viable, asserting that it will "comfortably meet Stage 4 noise requirements."
Speaking in Washington at the Eco-Aviation conference presented by ATW and Leeham Co., Strategic Marketing Manager-Future Programs Paul Randall said the open rotor is "the true game-changer" and could provide a 25%-30% fuel efficiency gain over turbofans powering narrowbodies today and be 10%-15% more fuel efficient than advanced turbofans that may come on line in the next decade. "Now the open rotor has moved from being a physics problem to an engineering problem," he said. "It is real and it is being realized."

Armed Crop Dusters Go To War
The AT-802U, a crop duster adopted to counter-insurgency missions, is trying to challenge the basic trainer aircraft that have been monopolizing this small market. The AT-802U is a 7.2 ton, single engine aircraft with a useful load of 4.2 tons. Cruise speed is 307 kilometers an hour, but is built to operate efficiently at 240 kilometers an hour. Slowest speed is about 180 kilometers an hour. Endurance varies, depending on fuel used (normally it takes ten pounds of fuel a minute).

Blanket provides protection against dirty bombs
The first instinct when confronted with a radiological explosive device may be to turn tail and run, but the new Demron-W Nuclear/Ballistic Shield affords the opportunity to stick around and save the day.
The Demron suppression blanket provides total protection against ballistics, improvised explosive devices, dirty bombs, spills, and all types of radiological and nuclear incidents, according to Miami-based manufacturer Radiation Shield Technologies (RST).
