Uber eVTOL CRM OpenVSP Models

[Felix Finger]

Hello Rob,

at AHS Mark Moore presented Uber's common reference models for eVTOL aircraft. Obviously the models were designed using OpenVSP.

His slides are available here: https://vtol.org/download.cfm?downloadfile=773A49A0-053E-11E8-899B005056BF91B4&typename=dmFile&fieldname=filename
Relevant are slides 7, 8, and 14.

Unfortunatly, this is all the data I could find on this topic. Do you know how to get access to the reference models and data? Will the models be made available in the Hangar or do I have to contact Uber directly?

I'm currently doing my PhD on the topic of sizing methods for electric and hybrid-electric CTOL and VTOL aircraft (first results will be published at the Aviation Forum and EATS this year), and I'd really test my methodology with these two models.

Thank you and best regards,
Felix Finger

If anyone else is looking for the models: They were published today on the Uber website, just in time for the Elevate Summit:

I think it's great to see how the developers build their own models. Great to see them published.

Regards,
Felix

Hi,

I struggle to convert this format .vsp3 to any useful 3D format. Did anyone solve the problem? I can handle almost all formats.

Many thanks, appreciated.

What can you use?  It is trivial to convert to STEP, IGES, STL, and many others.

Hi Rob,

Thanks for your reply! 

I got any option, .Obj, .stl, dxf, dwg, iges - any of these work. I tried the converter openvsp, but it shows error loading the files. Do you have any solution or help?

Many thanks,

1. Download open vsp from the web site. 

2. Unzip the file. 

3. Double click 'vsp' to run. 

4. Use file... open... dialog to open your file. 

5. Use file... export...  IGES... dialog to export.

Hello Rob,

Following-up on this discussion, is there some way to export the 3D model in OpenVSP into a format where it can be displayed on a web browser; so that somebody who has access to that page can perform actions such as zoom, rotate etc. in 3D.

Thank you.

We do this for the Hangar.

Use the X3D export.  Then, check out X3DOM to integrate that content into your website.

Hi Rob,

Perfect. That worked pretty well. I was able to integrate that into the browser using X3DOM. Is there some way to export the openVSP geometry in the '.x3d' format from python using SUAVE without using the GUI?

Thank you

[Rob McDonald]

The script that runs on the OpenVSP Hangar looks something like this (in vspscript -- translating to Python should be easy enough).

void main()
{
    // Get if there is any geoms
    array<string> @geoms = FindGeoms();

    if (geoms.length() <= 0)
    {
        VSPExit(1);
    }

    // Get VSP File Name
    string fname = GetVSPFileName();

    // Remove extension and add ".x3d" to the file name
    int found = fname.findLast(".");
    string base_name = fname.substr(0,found);
    string x3d_name = base_name + ".x3d";
    Print("x3d Name = ", false);
    Print(x3d_name, true);

    // Export X3D file
    ExportFile(x3d_name, SET_ALL, EXPORT_X3D );
}

Perfect. That worked. Thank you, Rob.

Best,
