Aeronautical Engineering Help needed
Hello,
I am looking into modifying one of the canard designs like the COZY MkIV and wanted to know what the best way to ensure that what changes I am proposing are sound and will result in a craft that will exhibit similar flight charteristics but with increase in performance (range, gross weight, acrobatic strength, etc...) Are there any software programs out there that would assist in the design changes? Any modelling software to show what affect the changes would have? Thanks! Marc

You obviously don't know Nat very well. If it's in regards to changing HIS
design, he will NOT be tickled to help you. BTDT have the T Shirt John Stricker "Larry Smith" wrote in message ... "Marc A. Lefebvre US-775" wrote in message m...

Hi Marc,
I frequently get questions from folks who want to make changes to my design. It's human nature to want to build "a better mouse trap". There are several available chart type plots of general aerodynamic formulas boiled down into graphic comparisons of areas, forces, speeds, weights,.........etc. (I.E. McCoy's, or Beaujon's aerodynamic tablature) You won't get any solid usable advice (none you want to hear) from a design holder or probably many builders either. Do the aerodynamic calculations and intentionally over build strength-wise. You're almost on your own. .....Guess that's why we're "Experimental" aviators. ......Good luck!

Nat Puffer wouldnt be able to help as it is NOT with HIS design, as I
said a canard design "LIKE" the COZY. I suppose if I had said "like" a Long-EZ you would have recomended Burt as well? hehehehe... Try again... Looking for modelling software, not people... Looking to do some analysis of some designs. Something along the lines of a virtual wind tunnel testing, stress and load testing, etc... There has to be someone with a clue in this group somewhere.
