I've been trying to get up to speed a little more with the rest of the world. I was directed to javafoil which is a free site . Anyone have much experience...
Hi John, I downloaded it last spring and started playing with it. Seems very complete but I didn't give it enough time before summer arrived. I couldn't find a...
Wow, that thing looks like a bee hive. I wonder how it worked. I see you posted that originally. Where did you find that and did it have a name? Deane ... ...
John, In thinking about such a design, wing rotation would be difficult. How sailable would your winged boats be if the wing was not able to rotate (fixed...
The wing has to respond quickly to gusts just like a regular sail . I n my case its much easier and quicker to sheet out the main win rather than adjusting the...
I think there was afew madr . I think one of them was call Finch vector or something like that. Its mentioned in an old iceboating book. ... From: "Williams,...
In that case I would guess the skate sailor has to respond quickly by leaning into the wind since he can't "sheet out". I wonder if our rigid wing was fitted...
We were able to make a file of my main , slotted flap including pivot point with cad program or something like that and load it into java . We tested the...
I would think the wing could rotate while you were inside it. In my case I would end up with a short fat wing to fit my class size. But it would be interesting...
... case I would end up with a short fat wing to fit my class size. But it would be interesting to try. John I don't see how it could rotate much with you...
... Hello to the group. My name is Byron Tetzlaff and I've been enjoying the chance to learn from you gents. I'm an iceboater and follow some of the wing...
... Anders Ansar has been to the Landsailing America's Cup several times. He's well known to many landsailors. ... Yes, it has low parasite drag. However, it...
I hope I'm not being a pest! But, in Mr Ander's website, he mentions tailoring the wing size for maximum performance in a given wind speed range. I'm a...
Hi Byron, A local guy named George Stulgaitis built one of these a few years ago & it worked pretty well, but I doubt it would ever come close to keeping up...
... Hi Bill!! Yes, I'd like to see what he built. ... Your K1 looks good. You'll have to let me know the next time it's sailing. I'd like to see it in person. ...
Byron, Welcome to the website. I am into making wings for racing or pleasure sailing. A few wings are made strictly for speed. The speed type of wings are made...
... The speed range for a given wing design depends in large part on the platform to which it is mounted. It's a system design issue. The performance of any...
-Tom is right about the platform stability factor. The typical wingboat has a much larger platform than a boat with a mast and sail. For example my last boat...
... The key to any airfoil analysis code is the boundary layer calculation. Javafoil's BL method cannot handle laminar separation bubbles, which is how...
Tom I posted some of the info after running my sections through Javafoil. Its located in photos http://ph.groups.yahoo.com/group/wingboats/photos/browse/a00e ...
Thank you John and Tom Your detailed response has cleared up a number of misconceptions. I look forward to watching the progress of your continued development...
Tom What software is available that can do the boundary layer calculations required to handle laminar separation bubbles as well as handling multi-element...
Frank , I started work on your plank. I had to cut off some wane from the wood and the plank ended at 9'' wide. The thickness is 3''. I will need some...
John We have a design for the removable flap using disconnects at the wing pivot hinge so removing the flap is a snap. I can also make a wing tee attachment...
John Thats great news. I planned on making the final designs for the plank saddle area after I received the plank. All I needed to know is the thickness and...
John I just looked at the pictures of the plank and it looks great. Frank johhnysrocket2003 <johhnysrocket2003@...> wrote: Frank , I started work on your...
I finally have begun work on the bulkheads. The design is John's Wingnut 3 except I am a machinist and not a cabnetmaker so I have to use metal instead of wood...
