Sydney Standard Aerodynamic Models (SSAM) Fifth Generation Benchmark Model Aircraft

[Koaib Kaleem]

Hi everyone,

Has anyone developed the vsp cad model of SSAM Fifth generation aircraft model (https://doi.org/10.3390/aerospace10090746).

If i have to start from scratch, then is Fit Model the correct and only approach? Kindly guide if any other steps/ approaches might be available?

Thankyou

I'm not seeing anything on the Airshow (https://airshow.openvsp.org/).  Fit Model and lots of matched components will be the way to go.  I also see this is relevant to your other post about planar slices.

Yes, have tried to match the wings and tails exactly with the stl and trying to model fuselage using fit model as well as visualizing it through slices at specific locs (the stl is very noisy).

Will be sharing it shortly so that someone can review it too.

regards

Hi,

I have tried modelling the geom, would be very kind if someone inspects it a little bit for accuarcy as well as any tips etc. if geomrtry seems problematic. meshgeom is the stl file i tried to replicate

Thank you

The model looks very nice compared to my higher resolution STL. The resolution might be overkill but should provide clean targets or surfaces for you to match. The file is too large to send here but I have an idea for how to get it to you.

There are the usual skinning recommendations I can see that would improve the surfaces and a few areas where the surfaces don't quite line up but those should be an easy fix.  

I don't immediately have time to document everything for you, although I would like to. This is a really good match, already.
For the moment, have a look at the MQ-28 model from the 2023 VSP Workshop https://openvsp.org/wiki/doku.php?id=workshop2023. It might give you some ideas.

I was able to put the mesh in a VSP3 file by itself and upload it to the VSP Airshow here: https://airshow.openvsp.org/vsp/d4YpX7CDokvy9kNNV2cj

Let me know if you have any issues downloading.
