    We are on the lookout for anthropometric 95th percentile adult male and 5th percentile adult female CAD drawings. 2D, .dwg or .dxf format. Googled to the ends of the known interwebs, and our search came up near dry. We did drawings in-house, but we are wanting to make sure our product meets the standard. We are doing a 2 seat side by side aircraft; we want to be 90% correct before we start cockpit mockups.

    What we are looking for is something like a "Two-Dimensional Drawing Board Manikin", seen below, but in a CAD format.

    The block drawing file doesn't have to be fancy....just needs to be to standard. If anyone has a half decent CAD file of at least a 95th percentile adult male, with anthropometrically and anatomically correct body joint points and such, we would be greatly appreciative!

    Time is money and 2D isn't going to be much better than hand sketches for this. BT.DT.GTTSTPI. You need 3D, or just go buy some foam sheet, OSB, duct tape and start cutting. You should do this even after designing using 3D just to double check with a real live wiggling human so why not start there?

    There are plenty of sources on the net for 95 percentile ergonomic dimensions of the human body. Try some different search words.

    We hear you, and have a treasure trove of human factors data. Was wondering if there were any standard products out there. We want to verify our drawing product (based on measuring up a couple of people) in an effort to make sure we 'got it right'.

    Think of it like a typical QA process- Check, Verify, Recheck, Certify

    But, thanks much for the input. We'll get there!

    Can't help with the models but the best online data set I have found is this NASA site
    https://msis.jsc.nasa.gov/sections/section03.htm

    One thing that about anthropometric data that isn't stated as often as it should be, is that the measurements are independent i.e.95% percentile height doesn't not mean the person will have a 95% leg or back length.

    If your software will read obj format, try here:

    p.s. How do you intend to pose the figure?

    What I mean by "posing" is how are you going to bend the CAD figure to sit in your cockpit? Having a figure is fine but unless you intend to have your pilot stand (like an early Sikorsky design), you need software that will pose your figure in your CAD drawing. See attached.

    Here is an example from some of our early work on an aircraft we are calling "Phoenix":

    Looks a lot like what I used in my 2D CAD days. I found it faster to simply print the pieces, cut them out, pin them together then manipulate them by hand on a print of the cockpit area.

    So, tell us more about the Horten wing... :)

    I have no idea what you mean by 'artrkkhte....95%' or ... percentile ....

    But if you want to use my test crew just ask.

    I fly them over at light-speed.:)



    The shortest is 1.60 meter, the long one 2.00 meter.

    These guy's are made out of solids. (3D environment)

    Our creation, the LV-14X "Phoenix", is a two-place, all composite, all-wing aircraft. Power will come from a Rotax 912. Currently completing the testing and evaluation of a 25% scale proof of concept model, while also fabricating select structural subassemblies! The goal will be to offer the bird as a kit in due course in 2021!
