KOMPAS.com - A pocket-sized spy drone disguised as a hummingbird has been unveiled by a major Pentagon contractor measuring just 16 centimetres and weighing less than an AA battery. The mini spy plane can fly up to 11 miles an hour and took five years to develop at a cost of $4million.
Army chiefs hope to use the drone’s tiny camera to spy on enemy positions in war zones without arousing detection and eventually deploy it into both rural and urban environments.
Experts hope the drone, which can fly just by flapping its wings, compared with current models which rely on propellers, will eventually be able to swoop through open windows and perch on power lines.
The demonstration by AeroVironment – one of the world’s biggest drone suppliers – lasted eight minutes and saw the new creation fly through a door into an building and out again, and withstand winds of five miles per hour.
Todd Hylton, Hummingbird programme manager for the Pentagon’s research arm said it ‘paves the way for a new generation of aircraft with the agility and appearance of small birds.’
Matt Keennon, AeroVironment’s manager on the project, said the milestone of building a machine inspired by nature pushes the limits of aerodynamics.
He added: ‘This is a new form of man-made flight’.
Two years ago the company showed off its first Hummingbird prototype, managing just 20 seconds. The latest flight lasted eight minutes, with engineers expecting longer flights as development continues.
AeroVironment already produces a number of different drones for the US Army. Last year it had 2,182 orders from the army for its Raven drone, which weighs four pounds with a wingspan of four-and-a-half feet.
Around 86 per cent of its orders come from the Government, meaning last year it was paid a whopping $215million from the Department of Defense.
