New coatings could protect jet engines from volcanic ash

New coatings could protect jet engines from volcanic ash: "Following last April's historic eruption of the Eyjafjallajökull volcano in Iceland, commercial flights were cancelled within most of Europe for several days – it was the largest disruption of air travel since the Second World War. Well, while no one is suggesting that airliners could now merrily fly right through clouds of ash, researchers from Ohio State University (OSU) have developed a coating that they say could allow jet engines to better withstand small amounts of volcanic ash that are ingested over time."
