craft that carries its own energy source, and uses only the flapping wings for propulsion and control. The milestone was part of the Phase II contract awarded by the Defense Advanced Research Projects Agency (DARPA) to AV to design and build a flying prototype “hummingbird-like” aircraft for the Nano Air Vehi- cle (NAV) program.

The final concept demonstrator is called the Nano Hummingbird and is capable of climbing and descending vertically, flying sideways left and right, flying forward and backward, as well as rotating clockwise and counter-clockwise, under remote control and carrying a video camera payload. During the demonstration the Nano Hummingbird flew in and out of a building through a normal-size doorway.
The hand-made prototype aircraft has a wing- span of 16 centimeters (6.5 inches) tip-to-tip and has a total flying weight of 19 grams (2/3 ounce), which is less than the weight of a common AA battery. This includes all the systems required for flight; batteries, motors, communications systems and video camera. The aircraft can be fitted with a removable body fairing, which is shaped to have the appearance of a real hummingbird. The aircraft is larger and heavier than an average hummingbird, but is smaller and lighter than the largest hummingbird currently found in nature.
“The historic achievement made by the Nano Hummingbird is an example of the leading-edge innova- tions introduced and deployed almost routinely by the AeroVironment UAS team,” said Tom Herring, AV senior vice president and general manager of Unmanned Aircraft Systems. “From the battle-proven Raven, Wasp and Puma small UAS to the tiny Nano Hummingbird to Global Observer, the largest, highest and longest flying UAS, AeroVironment continues to define the future of unmanned aircraft systems. Our mission in doing so is to provide our customers with advanced tools that help them succeed.”
