June 19, 2007 The A160T Hummingbird unmanned rotorcraft successfully completed its first flight last Friday. The turbine-powered version of Boeing’s piston-powered A160 helicopter offers some unique advantages such as a remarkable range, endurance, payload and altitude. The autonomous Hummingbird features a unique optimum speed rotor technology that significantly improves overall performance efficiency by adjusting the rotor system's revolutions per minute at different altitudes, gross weights and cruise speeds. The A160T will eventually fly more than 140 knots with a ceiling of 30,000 ft and a high hover capability up to 15,000 ft. Operational A160Ts will be capable of persistent intelligence, surveillance and reconnaissance; target acquisition; direct action; communication relay and precision re-supply missions for up to 20 hours at a time.
