The rule prohibited the foil from translating at the hull exit. So yes that was the pivot, more or less, presumably. Some sort of spherical...
Nice. Thanks for sharing. I only mention it because you talked about the cost being significant. Those figures seem fine for production stuff,...
For real.
Ps I think you guys are getting far too carried away with tooling quality if you are paying that much. Molds like that can be knocked together...
Seems like machining from billet doesn't get you the nice long surface fibers on the outside to hold the package together. I suppose you could...
Then I suppose one could increase the % thickness at the root to keep the wetted surface area down for the root, which is rarely immersed at...
Sorry I did not see tspeer's reply before my last post. I suspect it is a lot easier to keep a radiused bend on an L foil from cavitating than...
I think you misunderstood my comment. The "structural argument" refers to Dr. Speer's comment on L vs T. Obviously the L puts more bending...
Not sure I buy the structural argument. Just make the strut thick enough where it needs to be thick. It is out of the water most to the time anyway.
Initially I was just trying to get a feel for how much anhedreal is optimal; aVL should do that. But I spent a lot of time with OpenFOAM....
My limited foray into meshing has made me appreciate panel codes. I do not know how to get geometry this complicated into something like aVL...
Thank You Mr./Dr. Speer. I would think putting a point on the lifting foil and staggering the strut are to some extent accomplishing the same...
Thank you Dr. Drela - that configuration is close to what I remember. I basically did what Hoerner told me to do; I had a minimum thickness in...
A question for Tom Speer (if he is still listening on this channel): OK so the latest Oracle rudders had a bit of bullet fairing on the front....
I actually went back and forth with Paul Larsen and co a bit on their blog comments about this idea. Essentially, back when they were using their...
Um, Paul B if you were there, you know that the reason so many boats didn't complete more races is because there was f-all wind for most of them,...
Point of contention: there are lots of nice vids on YouTube of Mango and other streamlined recumbent bikes being used as commuter vehicles:...
That was probably me with the Moth. I get questions from interested juniors all the time. One of my favorite photos is of a crowd of ten or so...
There are much less risky places to save weight. And unless the class has no minimum weight, it seems penny wise/pound foolish to trust such an...
Thanks for your thoughts Dr. Speer. I modeled a truly elliptical planform, because that is what my current foil is. Most of the bending occurs...
