The surprising aerodynamics behind the Brazuca World Cup football

By - June 17, 2014 3 Pictures
Under the guise of World Cup fever, scientists across the globe are seizing the opportunity to examine the aerodynamic properties of what will in all likelihood be the most talked-about object on a global scale over the coming weeks, the 2014 World Cup match ball. The ball, lovingly named Brazuca by the Brazilian people, is the product of a significant amount of research and money aimed at creating the ultimate centerpiece for one of the greatest sporting competitions on Earth.

Jaguar teams with Pinarello for Tour de France bike

By - May 29, 2014 10 Pictures
McLaren, Aston Martin, Lamborghini and Ferrari have all done it ... now Jaguar Land Rover has done it, too. The legendary automaker recently joined forces with a major bicycle manufacturer, to create a super high-end bike. In this case, Jag collaborated with Italy's Pinarello to design the new Dogma F8 road bike, which will be used by the Team Sky racing team for the rest of the 2014 season. Read More

Shape-changing wings inspire more efficient aircraft designs

By - May 24, 2014 1 Picture
We tend to think of aeronautical engineering as having left the birds standing still sometime around the First World War, but since jet fighters can’t perch and quadcopters can’t snag salmon out of a stream, we still have a few things to learn. Taking a couple of pages from the avian playbook, Fraunhofer Institute for Electronic Nano Systems (ENAS) and its partners are developing wing flaps for airplanes that change shape like a bird’s wing for greater efficiency.

Aerion's AS2 supersonic business jet gets extra engine and cabin space

By - May 20, 2014 7 Pictures
Aerion Corporation has upped the cabin size and added an extra engine to the first in its planned range of supersonic business jets currently on the drawing board. Designed with Supersonic Natural Laminar Flow (SNLF) wing technology that was tested in transonic wind tunnel tests and in NASA flight trials, the Aerion AS2 will now use a set of three smaller jet engines in place of its previous large two-jet design to provide quieter running, improved take-off performance, and longer range.

University of Liverpool team aims to hit 90 mph in pedal-powered Arion1 Velocipede

By - April 24, 2014 5 Pictures
Last September, at the World Human Powered Speed Challenge at Battle Mountain in Nevada, a Dutch team made up of students from TU Delft and VU Amsterdam set the current world speed record of 83.13 mph (133.78 km/h) for an unpaced cyclist on flat ground in the VeloX3. The University of Liverpool Velocipede Team (ULVT) has now announced its intentions to take the title with the Arion1 Velocipede, a bicycle resembling an oversized medicine capsule that has been left out in the sun too long.

Upper Wheel Fairings are designed to give bicycle wind resistance the slip

By - April 24, 2014 7 Pictures
If you were designing a vehicle to be as aerodynamic as possible, it would definitely be counterproductive if parts of that vehicle actually moved into the oncoming wind. According to Los Angeles-based engineer Garth Magee, however, that's just what the forward-turning top sections of bicycle wheels do. His solution? Upper Wheel Fairings, which shield the spokes from the breeze. He claims that cyclists using his fairings can go up to 20 percent faster without any extra effort. Read More

A new understanding of flying snakes may lead to advances in technology

By - March 6, 2014 3 Pictures
So first of all ... yes, flying snakes do exist. Disappointingly, though, they don't have scaly dragon-like wings. Instead, they're able to flatten out their bodies after launching themselves from tree branches, proceeding to glide through the air for up to 100 feet (30.5 m). Recently, scientists figured out why that technique works as well as it does. Their findings could have some major applications for us humans. Read More
