CFM Engine Blade Sound
Hi all,
Just a question out of curiousity here. On my company's (Orange and White planes) A320's the engines clank like crazy in high winds when shut down an parked. I know this is because there is a small amount of lateral play allowed between each LP Turbine blade. However on the competitor's (Blue and Yellow planes) 737-800's parked next door in those same high winds don't make nearly as much noise and just make a quiet wooshing sounds. They're both variations of CFM 56 engines so why the difference?
