We had a high speed fan that failed. It appears that the fan ingested something, which caused damage to the leading edge of all of the fan blades.
One of the fan blades broke off near the root. The thing that is surprising to me is the fracture patern in the broken fan blade. There appear to be two distinct mechanisms that cause the failure - does this suggest that cracking was occuring before the fan ingested something? A photo is attached.
Thank you in advance for your expertise and comments.
