Aviation Week reports on the inner workings of Boeing’s Phantom Eye HALE (High Altitude Long Endurance) unmanned aerial vehicle.  The craft, now being tested at NASA Dryden Flight Test Center at Edwards Air Force Base, has a rotund character that shows form does follow function. Wrapping two eight-foot diameter hydrogen tanks in a low-drag pod and boom style fuselage, the “bulbous” but aerodynamic shape seems at variance with its sailplane-like 150-foot wings.  Overall, the design’s unlikely look conceals its purpose as well as its enormous fuel tanks. According to Aviation Week, “Boeing’s objective is a production HALE UAV [unmanned aerial vehicle] with an endurance of 10 days, which would enable it to remain on station for four days at 10,000nm [nautical miles] range, or six days at 6,000nm. Three such air vehicles would be able to maintain continuous surveillance anywhere on Earth, [Boeing Phantom Works’ Keith] Monteith says, for a dramatic reduction in cost compared with today’s 24- to 36h-endurance UAVs.” With …
