Nick Thomas You are most welcome Nick, she was an amazing aircraft wasn't she.
howiehowie93 It's so easy to forget the 'other' applications of this incredible engine. As welll as the industrial applications, the 'OLY' was of course also used on the Type 42 Destroyers and Invincible class carriers. The Olypus 593-610-28 used on Concorde also had a 'verboten' sustained N1 band, again due to turbine fatigue reasons. (I seem to remember that it was a resonance issue).
