I agree that you definitely can't trust AI. I've been using Google Gemini to bounce ideas off of, and have caught it flatly contradicting itself...
Ahhh....bummer! Well, worth a try. But don't sell yourself short. 736W is nothing to sneeze at.
Useful data, thanks! Hey, would you like to volunteer to pilot my silly boat, should I ever get it built? You sound like a pretty serious...
Or..... Scrap all the above, and use the Cardan gears for compactness and because you already have them. But use a set above and below, please,...
Ah, Victor....Nah. You do you, but for what it's worth, I'd do something like salvage two bicycle wheels, put them one atop the other, and use...
OK, here we go--same radius, same 4R travel, superimposed: [ATTACH] Yep, a lot bigger, although the "slave" pitch control mechanism adds quite a...
I find myself in complete agreement with this. Especially with Voith-Schneider types, although I'd agree it seems like the same issue with rotrary...
Hmmm...I'm aware that Newtons are a measure of force not power, so what might I have been thinking of? I guess that thrust is force, and that's...
Hi, Kerosene! Thanks for weighing in. Well, a few things-- First, do you mean harder as in more draining, or more difficult to get the same...
Good call on this. I'm actually reminded of a very old patent for a diesel-type free piston / gas turbine engine that proposed a rotary generator...
Aha. I guess I thought you were keeping your same transverse path on your earlier animations/diagrams, and were proposing to present your foils...
PS- that's also why I want the steps. Even in a non-stepped boat, it's the downward acceleration of the water at contact that creates lift....
Hmm. If so, that makes me wonder. It can't be (Newtonian) lift, right? One assumes you're not gliding your wheels over the water. And it can't be...
Yep, I'm familiar with it. Their speed foil is really tiny, like 2 ft span and 2.5 inches chord. I'm trying to do the same thing by rising up out...
@portacruise - What figures in to your guess on a water plane? My biggest concern is getting up on plane in the first place, as it takes a big...
You could always look into a Bolger Nymph: duckworksmagazine.com/07/projects/nymph/index.htm. 2 sheets of 1/4 ply, around 70 lbs, seats two people...
Not sure what "SOR" refers to, but yes, the OP (me) is primarily interested in the 100m flying start event, although I don't think either the...
Not sure I follow the logic here. The total drag of the flyak, or any hydrofoiling boat, has to be less than the displacement hull for the same...
I have read that some accuse Drela and Decavitator of having had a tailwind (as well as going downriver) in their record 100m run. I believe they...
OK. I don't understand the details, but I'll take your word for it. ;). Are you using two fins, or one? If two, could you obtain steering by...
