Well, that's in some way the reason for a forum like this one ...
The Intora Firebird was surprisingly hard to track, at least with a quick search. The UK based company
was acquired around 2009 by the Swiss Innosuisse, respectively its rotorcraft branch Swisscopter, the
engines seems to be in the reposnsibility of the Mexican TAM (Tecnologia Aeroespacial Mexicana) now.
They are hydrogen peroxide rocket engines and in the first exampes of that heli, this fuel had a pureness
of around 96%, which could be reduced later to 50%, or at least that was the aim, as that fuel could be a
bit problematic.
Some links about the Intora Firebird and its developments, one of them a German forum thread, sorry:
