The consequences of volcanic dust in jet engines

Sunday, April 18. 2010

Michiel points in a comment to interesting photos of an jet engine that ingested volcanic ash : "PICTURES: Finnish F-18 engine check reveals effects of volcanic dust". Perhaps the airline managers should keep this in mind when they are upset about the closed airports.

Perhaps you should mention that this is a jet fighter engine and not a regular airliner engine. There's about an order of magnitude between those two in regards of temperature and other conditions inside.
Regular airliner propulsion engines just need to pass the dust-infested air through them, and several test flights in the last days have shown that this is possible without any damage to the engines. The flight ban currently is only based on two incidents from twenty years ago, and which (as far as I know) didn't even result in a crash.

1. Especially the British Airways crash could only prevented by luck and great airmanship. Luck and great airmanship shouldn't be a factor in daily operations.

2. The core temperature of an jet engine (1400 degrees Celsius - military and civil) is significantly above the melting point of vulcanic ash (1100 degrees Celsius)

3. There is another report of an F16 jet engine with similar effects like the F18 ...
