The engines on the very early model Tristars had an even longer "hot section" fitted. It was shown through tests though, that they offered no performance gains, so a redesigned shorter "hot section" covering was installed, and early models were retrofitted with the samller and lighter units.
Thanks a lot Empress, I knew it would be something incrediby simple. I knew that something was not right, but I knew that it would be a simple explanation from someone else.
