Here are a few formulas for determining the balance of a wing boat. The first is to locate were the wing should sit on the boat. The second helps determine how...
Good stuff John, thanks for sharing. Those formulas are a candidate for Excel ! If anyone comes up with an Excel spread sheet (before I do, I'm at work now)...
Thanks Deane, They are derived from trial and error from what I've experienced from my boats and some feedback I've gotten from other wing guys. I haven't ...
Somehow that seems counter-intuitive. I wonder what Tom would say. Swept wing aircraft are not as efficient as straight wing. Seems that the sweep rearward...
... FoilsimII is a potential flow code. It does not calculate the flow in the boundary layer. Getting lift at modest angles of attack is not the issue. Any...
... The induced drag, which many people attribute to tip loss (it actually comes from the entire wake), depends on the lift distribution along the span of the...
Is there a book or collection of books that anyone could recommend I read in order to come up to speed on basic aerodynamics? I'm no stranger to complex...
I may have miss stated what was discussed by the c guy. He commented that my boat seemed to have no rake in the wing profile. If the boat hiked the wing loses...
I have been picking a lot of peoples brains lately for feedback on the ST 40 Wingboat rules. Thanks for the imput. They are paired down significantly from what...
... A classic is Abbott & VonDoenhoff's "Theory of Wing Sections" from Dover Books. Much of the material from it can also be found in NACA- TR-824, "Summary...
Well we have been going over what will be the design rules for the ST or now ST49 . I started out with a million design requirements and now they boil down to...
John, Not of concern to this project but I can see no way that it costs $30K to build any iceboat unless you are paying for the labor and purchasing all...
It may be iceboater bs but I've talked to more than a few skeeter guys that say it costs $30,000.00 in materials to build a front cockpit type Clapp skeeter....
I finally layed out my sections and took measurements of what the mainwing and flap create on the lee side as a whole. I set a straight edge across the...
I am not suprized at the results on this article. I don't quite understand the purpose for such a large gap though. The author says it will have a higher lc if...
John I would like to buy 2 of them. How much do they cost? Frank johhnysrocket2003 <johhnysrocket2003@...> wrote: Frank, I didn't put anything on the...
John: The drawings and sketches in the files section make it clear you expect a fuselage with a flat, horizontal top to just forward of the mast, and a sloped...
Ken, I'm for curvature of the hull as long as it is not a compound curve. I did not have a true wedge shape in mind when writing the hull shape rule. Curvature...
Improve your light air sailing I've always enjoyed light air sailing. There is something about getting and keeping the boat hooked up in light air that appeals...
An international event is slated for the last week in March at Ivanpah dry lake bed near Las Vegas. The Pacific Rim consists of Australia, New Zealand and the...
... I've uploaded some papers to the Max_Airfoils files folder that might help. Take a look at Figure 13 in http://tinyurl.com/5rwp8p. The higher the design...
