[NSRCA-discussion] Strange looking plane from Patrick Lemonnier

[Dean Pappas]

Oh Yes!
Rutan Aircraft Factory ... I should have realized.
lots of airplanes have warts to fix stbility issues at high AOA. Look at the underside of a learJet.
 
I'm with Nat on this one, band-aids are fine, but solving the problem at its source is better.
Tall canopies have "funny" flow behind them. On the other hand, trout are shaped properly.
Okay, maybe they'd fit on my plate better if they were round ...

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.
