[NSRCA-discussion] Strange looking plane from Patrick Lemonnier

[White, Chris]

Yes Keith you are right and that's why I asked the question....all
designs are a compromise...but Beech had to overcome some real hurdles
on the 1900 D when they modified it so radically.  Remember it was not a
design-from-scratch airplane....it was a severe design derivative that
was made to work.

Yes, they couldn't get it right the first time.  

 

All of those little aerodynamic "thingys" are tacked on during
certification because the original design was lacking in one aspect or
another.

 

Why else would you add drag and complexity to a perfectly functioning
airplane?

Hi Dean,

Just curious, but do you think we could learn anything from RAC about
flow dynamics considering all the aerodynamic devices hung on the Beech
1900 D???:)  

Chris :-)

Now that is funny!

Why, you ask? Because just yesterday I was on the phone with Matt K. and
said to him that the vertical part of the flow straightener (translation
for canaliser) was not really necessary. I said that the basic purpose
is to make the airflow track down the length of the tailcone, rather
than spilling around the top, as the plane is yawed. That improves both
pitching behavior and knife edge power. When I get the needed weather, I
will hang a little straightener on the Funtana to see what happens to
its strong push to the belly in K.E. What about chine strips? I'll have
to try that, as they could be less ugly, and even add structural
stiffness.

later,

Dean

	The lastest incarnation of PL Products has a very strange plane
called the Axial.  Take a look.  This makes the t-canalizer look good by
comparison.
