A321 v2 noise (not PTU)
Hi. Not sure if I'm posting in the correct area - I'm not a professional, so this looks nearest.
Boarding an A321 today and couldnt help noticing a loud noise coming from the port/number 1 engine. I can best describe it as a clanking/clattering, similar to the sound you might get from a couple of half bricks in an empty concrete mixer.
Drew this to the attention of cabin crew, and basically advised it was nothing to worry about. Not that anyone took the trouble to actually check it out.
Anyhow from inside the noise was not apparent, and the engines seemed perfectly normal throughout the flight and landing.
I am very curious what the origin of this might be. I couldn't see any other equipment nearby - the noise seemed to come from the turbine. I know pretty much nothing about aircraft engines, but have rebuilt many car and M/C engines, and if any one of them made a noise like this, I wouldnt be thinking of driving it.
Any thoughts? Thanks in advance.
