    Looking for anthropometric human CAD drawing files

    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.

    Move along - nothing to see here

    There is an important omission in the calculations for the "Constraint Analysis". Put there on purpose to see what would happen. All of the calculations are simple "hand, closed-form" calculations any high school algebra student should easily follow. Since no one commented on any of them, I...

    Celera 500L (was: More Vaporware)

    I kid you not. They stole my idea. This is identical to an aircraft I designed in 1986 except mine was smaller. I was going to power it with my ZL-1. What you do is take your favorite laminar flow airfoil and sweep it around a central axis. Presto, a laminar fuselage with minimal drag and...

    VSP

    Vigilant1, Thanks for the interest. I intend to start my own thread about my design. I don't want to go "off-topic" in this thread. I also appreciate the heads-up about "The Beetlemaster" thread. I will read it all.

    VSP

    OpenVSP is a fantastic program. It challenges you to be a good engineer... to further your understanding of the "how and why" of your aircraft design. It allows easy and quick reconfiguration of airfoils, cabin sizing, engine/prop placement, empennage sizing and a whole lot more. This is my...
