So, over the past week or so, jjn and I have been CADing up some 2019 spec wings for the PERRINN model in the future. jjn has created a "somewhat parametric" aerofoil profile distribution which allows us some control over the geometry, and hopefully we can take these models, and after I prepare them for meshing, get some of our own "design attempts" out there too
(or rather, more likely, we will CAD up something similar to existing teams wings and see if we can make any assumptions on performance... but shh!!)
For now though, we have somewhat "modified" the 2018 wings of the Perrinn to fit the 2019 spec and CFD'd them for you.
I will say that I wanted this to be the start of what will eventually become a "replacement" of all components of the Perrinn F1 model. The export of the baseline Perrinn CAD to .step was "dubious" and has taken me around about 20+ hours total of surface repairing and preparation for meshing, to the point now where part of the issues I am having with the meshing is that generating a patch conforming tetrahedral mesh is doable... just!! The inner "perfectionist" in how I prepare my own CAD for CFD is getting more and more frustrated with the lack of attention to creating good quality surfaces, most likely because the people running simulations just stick a mesh wrap over it and accept whatever it spits out. Not me...
Anyways, so... This time, I have prepared the CAD to a much higher standard (FW and RW only of course) and have replaced the originals. The result is a much higher quality mesh for the FW and RW, as well as, with many... MANY... meshing attempts... a slightly better overall quality mesh. I have now put our new geometry through a 4° Yaw case (similar to before) and finished post-processing as well.
The results are now in, and both jjn and I are studying the images and forces/torques outputs etc and will be back sometime soon with another update etc, but for now, here are some images of the new wings.
