Researchers study potential of drag-reducing devices on semi-trucks to conserve energy
Each year, the more than 2 million tractor-trailer trucks that cruise America's highways consume about 36 billion gallons of diesel fuel, representing more than 10 percent of the nation's entire petroleum ...
Building the world's fastest downhill racer
I'd like to say that it's not every day you get asked to try to break a world record with a speed-obsessed truck mechanic from Grimsby, but for us at the Centre for Sports Engineering Research it's starting ...
Investigators wrap site work in spaceship crash
Federal investigators who have been in the Mojave Desert trying to find out why an experimental spaceship crashed are wrapping up their work in Southern California.
Debris from downed spaceship found 35 miles away
Federal accident investigators say that tiny pieces of an experimental spaceship that broke up in flight have been found 35 miles from the main wreckage area.
Loudspeakers in jet engines
Unless one is attending an aeronautics convention or going on a trip, noise associated with aircraft engines is rarely tolerable. Different means of significantly reducing that noise are being tested by EPFL's Electromagnetics ...
Bat wing practice maximises flight efficiency
Australian bats developed a high-speed flying technology some 50 million years before aircraft engineers, according to Department of Parks and Wildlife zoologist Norm McKenzie.
Bringing back our spaceplane
Yesterday, the ship and crew aiming to recover Europe's unmanned IXV spacecraft in November had a practice run off the coast of Tuscany, Italy.
The secrets of owls' near noiseless wings
Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence.
Dinosaur wind tunnel test provides new insight into the evolution of bird flight (w/ Video)
A study into the aerodynamic performance of feathered dinosaurs, by scientists from the University of Southampton, has provided new insight into the evolution of bird flight.
Wide left: Study shows that holders play key role in field goal accuracy
NFL and college football teams are back in action, and their success often hinges on the accuracy of their field goal kickers. When the field goals are made, kickers are heroes. When they miss, they're goats. ...
World Solar Challenge: Resolution ready to shine down under
Built by undergraduates working for their exams, with funds raised by the students themselves, Cambridge's solar car is the only British entry into the World Solar Challenge. Despite the odds, however, its ...
Fluid dynamics: Resolving shockwaves more accurately
A new computational scheme enables more stable simulations of shockwaves in fluids and may be scalable for large engineering designs.
Human-powered helicopter wins Sikorsky prize
A Canadian-built helicopter that is powered by a human riding a bicycle has become the first winner of a decades-old $250,000 engineering prize, the US awarder said Friday.
Muscle power: Bats power take-off using recycled energy
Bats are uniquely able to stretch and store energy in their bicep and tricep tendons during take-off and climbing flight, giving them an extra power boost. A new study on fruitbats, to be presented at the ...
