NASA researchers are spending at least the next six months poring over data from a recent test that involved sending volcanic ash through an airplane engine.
According to the U.S. Geological Survey more than 80 commercial aircraft encountered potentially hazardous volcanic ash in flight and at airports from 1993-2008. That was before the big 2010 volcanic eruption of Eyjafjallajökull in Iceland which disrupted hundreds of flight in Europe and the lives of about 10 million airline passengers over six days.
"The primary issue is that volcanic ash forms glass in the hot sections of some engines," said John Lekki, NASA Vehicle Integrated Propulsion Research (VIPR) Principal Investigator, based at NASA's Glenn Research Center in Cleveland, Ohio. "This clogs cooling holes and chokes off flow within the engine which can eventually lead to an engine power loss. It is very erosive, which causes damage to compressor blades and other parts in the engine."
