Hi! All,
Just out of interest Frans Veldman and Iloona Koostra now have a catamaran and are in the southern middle of the Pacific.
They can be hooked up with on Utube under the cat name of zwerfcat nl . she has a very pleasant video for you to scan . Unfortunately I am not U-Tube familiar so when the U tube buffs find a proper kink please advise and return the favour.
Regards Bob Harrison Ex G-PTAG ….

Frans bought a yacht and is sailing around the world last I heard. We haven't talked since we collaborated on our cooling drag reduction project years ago.. You can catch him on Twitter from time to time. I believe that his fairings were provided by Fred if I'm not mistaken. - Paul

When we scanned the Europa we used paint that was washed off afterwards. It is commonly used by street artists. An initial attempt without paint led to big gaps in the cloud data.
I like the root fairings, they look a bit like Frans Veldman’s who was highly active in Europa modifications. Whatever happened to Frans?
The tape is probably a better idea, as it limits the data - although there are some coordinates for the sections along the wing - we used them years ago in xfoil.

Does anyone have a top down photo or plan drawing of the wing root fairing? A few guys on the post here were interested to see what the actual CFD simulation data would reveal? Thanks

Area 51 (sorry I can't find your name),
The plots you have posted look very interesting, but I have no knowledge of what they are really showing. Could you post some explanation of what the colors mean and how to interpret them or point us to a explanation document?
What I'd really like to see is an article for the Europa Flyer that explains your work and what it means to us.
It might also be helpful if you labelled each plot with what it is showing, not just the jpeg identifier.
Keep up the good work!
