[RCSE] AVL question

2008-05-28 Thread David Klein
I know that this is better suited for the X-foil discussion board, but I am
waiting for approval to join for a few days now.

I need to run some negative load factor run cases, inverted looping flight,
negative Cl.  AVL does not allow me to input the values into the looping
flight condition.  I thought I would try getting around this by building an
inverted aero model, using inverted airfoils, and an inverted tail.  It is
not running properly.  I will try to rebuild the model, and try again.

Is there an easier way to run negative lift load cases?

Thanks,
David

[RCSE] AVL Question

Gentlemen, for those of you with experience using Dr. Drela, and H.
Youngren's  AVL (Athena Vortex Lattice) software,  can you write the strip
forces to a file.  I need more loading information than the VM shear moment
forces.  I really need to write the strip forces to a file so I can
manipulate them with Excel or Matlab.

Thank You,
David Klein

Dave, the place to ask this question is the Yahoo group for Xfoil. There you 
will find many AVL users, and probably one or more who can tell you how to get 
what you need.
