Small finlets on owl feathers point the way to less aircraft noise

Posted by in categories: engineering, sustainability, transportation

A recent research study conducted by City, University of London’s Professor Christoph Bruecker and his team has revealed how micro-structured finlets on owl feathers enable silent flight and may show the way forward in reducing aircraft noise in future.

Professor bruecker is city’s royal academy of engineering research chair in nature-inspired sensing and flow control for sustainable transport and sir richard olver BAE systems chair for aeronautical engineering.

His team have published their discoveries in the Institute of Physics journal, Bioinspiration and Biomimetics in a paper titled ‘Flow turning effect and laminar control by the 3D curvature of leading edge serrations from owl wing.’
