Robot Birds: Designing Micro Air Vehicles

From his upturned palm, Ryan Carr launches then expertly flies what appears to be a remote-controlled bird. Later, the aeronautical engineer uses special equipment to examine the machine’s flight characteristics. scientist Joseph McDermott works at the Air Force Research Lab in Dayton, Ohio, with materials so tiny the width of a human hair is huge by comparison. Welcome to the world of micro air vehicles (MAVs) at Wright-Patterson Air Force Base. Here hobby-store aircraft are helping scientists design a futuristic line of miniature flying spy vehicles. We take the technology that we have and we try to design something that does the same thing as a hummingbird or dragonfly does,” explains Carr.

The music is an original track by BT, written just for this video. Check out http How Does This Work? This is one not to try at home. The Coke Zero & Mentos Rocket Car uses a piston mechanism: a six-foot long rod sits inside a six-foot long tube attached to each bottle of Coke Zero. When the Mentos drop into the soda, the pressure tries to push the rod out of the tube. With 108 rods all pushing at once, that gives us a lot of power. All that power is pushing against a wall braced with 3600 pounds of cement blocks. So all the force is directed into moving the Coke Zero & Mentos Rocket Car forward. We get one big push for six feet, and then it’s all coasting from there. Want to know what makes the soda fly out of the bottle? Will you explode if you …
