Future aerial design may owe a nod of thanks to five parrotlets flapping around in an instrumented flight chamber at Stanford University. They revealed that counter to conventional understanding of ...

There are many ways to describe the forces around sails — in fact, around any foil. One of the most straightforward ways is to split the forces into lift and drag. The lift force is, by definition, ...

Underwater or aerial vehicles with dimples like golf balls could be more efficient and maneuverable, a new prototype developed at the University of Michigan has demonstrated. Golf ball dimples cut ...

Airplane flight is one of the most significant technological achievements of the 20th century. The invention of the airplane allows people to travel from one side of the planet to the other in less ...

Researchers have investigated the aerodynamic performance of a single floating PV setup of 16 panels, as well as an array that combined 15 such setups. They found that drag coefficient distributions ...

I'm sure that everyone has at one time or another been caught doing this. It is also possible that your parents told you to stop doing it or bad things were going to happen. Clearly, I am talking ...
