The Hummingbird met or exceeded all of the demonstration requirements during the tests, conducted March 9 - March 11 at the US Army's Dugway Proving Ground, Utah.
Boeing showed that the A160T could deliver at least 2500 pounds of cargo from one simulated forward-operating base to another 75 nautical miles away in well under the required six hours.
The simulated mission carried 1250-pound sling loads over two 150-nautical-mile round trips, with the A160T operating autonomously on a preprogrammed mission.
The A160T completed seven test flights during the demonstration, including a two-minute hover at 12,000 feet with the 1250-pound sling load, and a nighttime delivery to a simulated forward operating base.
The A160T's ability to execute extremely accurate autonomous deliveries also was demonstrated.
The A160T has a 2500-pound payload capacity.
It features a unique optimum-speed-rotor technology that significantly improves overall performance efficiency by adjusting the rotor's speed at different altitudes, gross weights and cruise speeds.
The autonomous unmanned aircraft, measuring 35 feet long with a 36-foot rotor diameter, has hovered at 20,000 feet and cruised at more than 140 knots.
The A160T established a world endurance record in its class in 2008 with an 18.7-hour unrefueled flight.
