New Military Drone Passes Vertical Takeoff Test
Posted: July 24th, 2009, 9:48 am
It flies like a butterfly, and boy, will it sting a lot more than a bee.
Aurora Flight Sciences recently tested a half-scale model of its new Excalibur unmanned aerial vehicle, or "drone" to the rest of us.
Unlike the military's Predator and Reaper drones currently in use along the Afghan-Pakistani border, the Excalibur won't need a runway.
That's because it's a vertical-takeoff-and-landing (VTOL) aircraft. Like a Harrier jet, it rises straight up off the ground before using forward thrust like a regular jet.
Three horizontally mounted propellers help a tilting turbojet push the craft up, and are then stowed away as the jet drops into flight position.
