Improved control of big power in little motors

Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems—but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories.

Toward urban air mobility: Air taxis with side-by-side rotors

In this high-resolution visualization of NASA's side-by-side, intermeshing rotor air taxi concept, researchers are working to understand complex rotor air flow interactions, simulated using high-fidelity computational fluid ...

Improving drone performance in headwinds

The prevalence of multi-rotor drones has increased dramatically in recent years, but in headwinds, they pitch upwards unpredictably. Engineers from Tohoku University, Japan, have shown that angling the rotor blades of a quad-rotor ...

Locked movement in molecular motor and rotor

For a motor to power machinery, the local motion has to be translated into the ordered movement of other parts of the system. University of Groningen organic chemists led by professor Ben Feringa are the first to achieve ...

New radar scanner tests wind turbine blades for defects

Thanks to the innovative radar scanner from the Fraunhofer Institute for Applied Solid State Physics IAF, defects in the material composition of the wind turbine blades can now be detected with far greater accuracy and visualized ...
