The recent
comments by Bill McDonald, about our turbine fuel system, quote "having a belly
tank is dangerous and stupid" which he attributes to some prior
comments ,that I haven't seen, on LML, indicates a
lack of understanding of the system.
Without
trying to describe the system on line, I'd like to point out that belly tanks
are not an unusual design feature, and that our system does not introduce air
into the engine FCU by design or during reasonable practice. His
statement that the vent system by "locking air out, but if air gets
in ( like running a wing tank dry) locks air in", is completely
incorrect.
As has been
pointed out recently, the fuel system on the plane that crashed in Georgia
was not of our design, and blaming the the accident on fuel system design, no
matter whose it is, by some one who has no facts, is, well you describe
it.
There are a
number of other statements in his posting that are questionable at best,
and many are attributed to John Cook the owner until recently of Diemech
Turbines Inc. who is a very knowledgeable about turbine engines, but who has not
as far as I know expressed his doubts to us.
All systems could be improved, nothing is
perfect, the space shuttle for example, and if any one has concerns about
the operation of our turbine fuel system, or suggestions to
improve our arrangement, after they understand how it
currently operates, we would like to hear from
you.
