AeroVironment has released a video of flight tests of its tiny Nano Hummingbird flapping-wing UAV, built under DARPA’s Nano Air Vehicle (NAV) program. As you watch the video, remember this vehicle, like a real hummingbird, is hovering, maneuvering and flying under its own power, using its flapping wings for propulsion and control.
This final concept demonstrator, built under Phase 2 of DARPA’s NAV program, has a wingspan of 16cm and weighs just 19 grams – less than an AA battery, says AeroVironment. Carrying batteries, motors, a video camera and comms links, the vehicle is bigger than the average hummingbird, but smaller and lighter than the largest of the species.
The remote-controlled Nano Hummingbird met or exceeded the Phase 2 goals, the company says, demonstrating: precision hover within a 2m-diameter “virtual sphere”; stable hover in wind gusts up to 5mph; hover endurance up to 8min without external power; transition from hover to forward flight up to 11mph; and flying from outdoors to indoors and back through a normal doorway.
AeroVironment has even fitted the vehicle with a removable fairing shaped like a hummingbird…
