| ...there is an earlier post related to the use of metal blades, which I initiated. There were several replies advising that they are not permitted for use under the AMA or BMFA rules.
However, as regarding their ability to cause greater damage than CF or GRP blades on contact with solid objects (humans), I believe there are no hard statistics available - it is perceived, more than likely incorrectly, that they would cause more damage as a rotating metal blade is likened to a more sinister object, designed to inflict damge, such a a knife or sword....
..I do remember one reply to the post, from an Australian Pilot, who had seen both CF/GRP blades & Metal baldes catistrophically fail in operation. I think he remarked the CF/GRP baldes splintered & broke up , whilst the metal blades bent & buckled, but remained intact, wrapping themselves around the head.
In my own experience, a shard of broken CF or GRP can be just as sharp than metal kitchen knife.
I think the ban by the AMA & BMFA is more down to psychological expectations of possible damage to flesh, rather than actual recorded injuries....a metal blade just seems to be more dangerous I think ?
If I can find the original post again, I'll post a link to it |
