Absolutely correct ; guess i got tricked by the topic title :TPink wrote: ...
the speed sailers have pretty universally found that foil cavitation takes place at approx 50 kts.
hi pedro.windfreak74 wrote:Guys thanks for taking the time to answer my question!
i guess my question is not relevant to the speed i will probably travel.
the speed on the video is not revealed.
My impression was that this was the first place where cavitation started.
when routing my wings i did the easiiest fastest way to do the profile without change of bit.
but if taken the proper time and chage of bit the transition can be made smooth without Sharp angles!
i guess i have to make my wings and strut connections with more atention!
just wanted to know if it made a big difference!
Yea , took several tries ; but got it .Edge19 wrote: .... I tried to see where it formed from, I took some screen shots and it looks like it came from a wing tip.....
You can see it at 3.29
No Way do i wanna even Try to argue the your point about fillets Vs sharp cornerszfennell wrote: ...
Regardless, sharp corners at any joint , whether they are internal or external tend to increase drag
The use of fillets where ever possible help reduce the formation of vorticity in corners, reduce the total exposed wetted area of the joint ( and its skin friction) and help stabilize the joint structurally.
but just some thoiughts.
