Sharkskin actually increases drag

On an intuitive level, you'd expect a shark's skin to reduce drag. After all, the purpose of sharkskin-inspired riblets—the micro-grooved structures found in aircraft wings, wind turbine blades and Olympic-class swimsuits—is ...

The way to more efficient, quieter wind turbines

A European research project aims to reduce the cost of wind energy generation by introducing technical improvements to turbines, which will have to be much quieter in the future than is the case today

Cutting costs in aircraft turbine production

Compressor disks for aircraft turbines are milled from a single piece of material. During processing, the blades begin to vibrate. Now, a novel clamping system boosts vibration absorption for the blades by more than 400 times, ...
