      Morning Bill,

      I would also like a copy of those spreadsheet if you don't mind. I have other things to do now, but it seems that this stuff might be helpful in the future.:)

      Thanks

      Hello Billski,
      Thanks for your offer of the Willford spreadsheets. I had downloaded a lot of these a long time ago and had completely forgotten I had them . I can't seem to find where they hid the spreadsheets at Osh365 so I wonder if you could tell me if I've missed any important ones. I have: structure, wood design, flying qualities, control surface balance, metal design, more-less, airloads, wing design, LG design, s204 design, cooling. I'm slogging along, learning this stuff from books and articles so these tools are very helpful.
      Thanks,
      Leland.

      I don't want to be a pain but I'd love to have your spreadsheets too so I can compare to what I have and see if I got everything covered.

      Thanks

      Flat plate area is he equivalent frontal area of an airplane, the fuselage, or whatever. It is the sum of A*Cd. The Long EZ's total flat plate area is about that of a standard piece of writing paper.

      I finally finished my cnc cutter and have 4 cubic meters of foam sitting in my basement.
      I am in the phase of defining the final design before cutting and would very much appreciate if you could send me the mentioned spreadsheets.
      My email is: sgarrido75@hotmail.com

      Hello:

      I would be very interested in receiving copies of the (Wilford?) EAA spreadsheets that are mentioned in a recent thread. Please send to architectbdd@yahoo.com. I think they had a Roncz spreadsheet or too at their site awhile ago. Is that what you are finding out? I am interested in them too. I let my EAA membership lapse mostly because the magazines don't have much of the practical and useable design info. that interests me so there are things at their site that I can't access. Not too wild about that either, by the way.:)

      Thanks,
      BDD

      Hi, I had a question regarding your post

      "I would get out TOWS, look up the v/V charts for the foil, interpolate to get the v/V for the C and D points for the envelope of this airplane (max g at stall AOA and max g at Vne). Then do the membrane analysis of the nose skin at the loadings the v/V indicates to see if glass at the thickness you are thinking about will stay on the airplane. Maybe the aluminum is the right stuff, maybe the glass is. You won't know without doing the analysis."

      Could you please point me in the direction of where I can find out how to do this membrane analysis? I've already searched the web and forum.

      Thanks.
      BTW, I have the specs for Scotchply, just not the method to design using it.
      I'm also having a bear of a time finding any. I've found sheets of similar material, but the strength and flex properties aren't anywhere near what Scotchply (Cyply) claims. I've only tried two distributors, but have gotten no where when I say that don't yet need production quantities of material - i need to TRY it first.
      Ideally, I'd like to find some 3-4" bar stock of the appropriate thickness. Ultimately, we'll probably end up making our own gear anyway, but I was hoping to save time and money in the beginning (it's easier to change a waterjet cut file than make a new mold).
      Thanks again for your help.

      Hi Bill,

      How is life?
      Here it is full speed ahead with boats and family.
      Need to put up some real effort to finish the new Propeller software, but time ...

      I hope you understand the irony in the PRSU thread, I don't know if the tread is comic or sad, maybe tragic comic :-)

      Hi
      Read you posts about Canopy latches and was impressed by the level of details that your going to! What are you designing / building? Be interested to hear details of your canopy hinge / latch mechanism and the general concept! Good building! Matthew
