(Phys.org)—An airplane's vortex generators, which look like small fins on its surface, improve the plane's aerodynamics similar to the way in which the dimples on a golf ball improve the ball's aerodynamics: by delaying ...
Every bit of weight on an aircraft increases the fuel, emissions and money required to put it in the air. NASA and Boeing have been working together to design a longer, thinner and lighter wing – so different from typical ...

(Phys.org)—In an attempt to harvest the kinetic energy of airflow, researchers have demonstrated the ability to harvest energy directly from the vibrations of a flexible, piezoelectric beam placed in a wind tunnel. While ...
(Phys.org) —A new study from Western University's Advanced Facility for Avian Research (AFAR) proves through experimentation that birds can predict changes in the weather by reading the rise and fall of barometric pressure.
