Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have always thought that what I was taught in school about wings was pretty much bulls**t and didn't give it all..This guy does an excellent job of explaining aerodynamics in detail and very understandable... So if you are curious about Aero and Fluid Dynamics this is worth the 60 min watch... BTW :: this guy really reminds me of Jake Raby in looks and presentation, he is just more scientific ....is it just me ?? You Tube
Very interesting! Thanks for posting this Doc. What we were always taught is “fundamentally” true, only there is a LOT more going on. So perhaps that coanda effect is what creates the outcome of cavitation in a fluid like water, where the force is great enough to actually blast away material from the wing (or prop in this case)? I had the unique opportunity to work around these SailGP sailboats this past year. The “wings” that they fly on (foils) were truly remarkable. The attention to the surfaces was incredible. In fact the trailing edge is so sharp that they will cut skin and had to be handled very carefully (considering they weight 300 lbs and are solid carbon fibre).

Yeah, the SailGP boats are insane! I had 18' and 32' catamarans and 22-26 mph was darn fast for a sailboat. My 32' could pull a water-skier! These new hydrofoil/techno boats go 45-55 mph! Maybe not for everyone, but totally amazing! Even the new "big" Blue-Water pleasure CATS, like Lagoon 42, are fast and comfortable, able to handle any almost any weather. Out of my $$ reach these days and a few decades too late. sigh. YMMV
@JTT Yes I thought the video was good especially how much that guy reminds me of Jake,...I got that video from Darin Morgan , he is probably the best head port designer there is in existence confirmed by his accomplishments in NASCAR NHRA and IHRA.... Air is both a fluid and a gas and these Laws of Physics apply to head port flow, Aero lift or Downforce, and oil flow and oil system and Sump Design...even the radiator cooling system design...

They clocked in a peak over 60 mph last June in Halifax. New �T� foils are even faster. All in an up close and personal manner, not 50 miles off shore like traditional boat racing. These guys sprayed the crowd as they streaked past wharfs. Supercross of sailing Back to the point of this thread though, the attention they gave to the hydrodynamics demonstrated how they could achieve these speeds. Those foils were treated like fine crystal. A whole shop was dedicated to maintaining the surfaces to maximize that boundary effect, as well as leading and trailing edges.
