Hummingbird helicopter robot

The Hummingbird features a unique optimum speed rotor technology thatsignificantly improves overall performance efficiency by adjusting therotor system's revolutions per minute at different altitudes, grossweights and cruisespeeds. The autonomous unmanned aircraft, measuring 35 feet long with a36-foot rotor diameter, eventually will fly more than 140 knots with aceiling of 25,000 to 30,000 ft. (high hover capability up to 15,000ft.) for up to 20 hours. Operational A160Ts will be capable ofpersistent intelligence, surveillance and reconnaissance; targetacquisition; direct action; communication relay and precision re-supply missions.
