Tilting at wind farms

A way to make wind power smoother and more efficient that exploits the inertia of a wind turbine rotor could help solve the problem of wind speed variation, according to research published in the International Journal of ...

NASA helicopter's mission ends after three years on Mars

NASA's Ingenuity Mars helicopter, which made history by achieving the first powered flight on another world, has officially ended its nearly three-year mission after sustaining rotor damage during its last outing, the space ...

Extreme testing for rotor blades

Wind turbines are growing bigger and bigger – the diameter of their rotor blades could soon reach 180 meters. But that creates a need for larger test rigs capable of accommodating the blades for load testing. One of ...

Using 'proton grease' to spin-up a molecular rotor

When designing the tiniest of possible machines, scientists have had far more success in creating molecular-size brakes than accelerators. But a team at the University of South Carolina has figured out how to really hit the ...

NASA Tweaks Tech Toolbox to Capture Tricky Rotor Results

(PhysOrg.com) -- "Smooth" and "quiet" are two words not usually associated with a helicopter ride, but NASA is working to change that. A full-size UH-60A Blackhawk helicopter rotor was the subject of tests the agency's Subsonic ...

What a ride! Researchers take molecules for a spin (w/ Video)

(PhysOrg.com) -- Kolomeisky and Rice graduate student Alexey Akimov have taken a large step toward defining the behavior of these molecular whirligigs with a new paper in the American Chemical Society's Journal of Physical ...

Ion wind technology breakthrough takes flight

A new spin on propulsion is taking flight in a SUNY Oswego lab, leading to electrical and computer engineering faculty member Adrian Ieta and the SUNY Research Foundation pursuing a patent on this promising technology.

Intelligently recovering and recycling balsa wood

There are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will shoot up to 15,000. But where to put these up to 90-meter-long, ...
