Aerodynamics, from Greek á¼Î®Ï aer (air) + Î´Ï
Î½Î±Î¼Î¹ÎºÎ® itself from Î´ÏÎ½Î±Î¼Î¹Ï dynamis (force ; specially, miraculous power), is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a solid object. Aerodynamics is a subfield of fluid dynamics and gas dynamics, with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics, with the difference being that gas dynamics applies to all gases.
If there’s something ever wrong with ping-pong guns is that they fire too slow. So, Mark French, a mechanical engineer at Purdue University in Indiana, along with a couple of his graduate students took it upon themselves to finally design a gun that can fires ping-pong balls at supersonic speeds. Of course, this makes for [...]
The now retired Concorde turbojets were the fastest civilian airliners in the world, capable of carrying passengers from Paris to New York in just 3.5 hours, traveling at supersonic speeds. However, lack of market appeal, combined with high maintenance costs, lead to its regrettable retirement from service with no civilian airliner to replace it, not even to [...]
Scientists have come a step closer to mimicking the aerodynamics of flying animals in nature, which might lead to the creation of flapping-winged aircraft in the future, after a new breakthrough in the field. The study, conducted by biomimetic researchers at New York University, finds that the ideal weight-distribution for hovering is totally opposite from [...]
I’m still left in awe after stumbling across this marvelous feat of engineering, which perfectly applies nature’s concepts to science and engineering technology. Seeing the SmartBird model in action immediately makes one imagine one of the world’s greatest minds Leonardo da Vinci on Florence’s hilltops studying and sketching the flight of birds for his aeronautical [...]
