Supporting various projects at Penn State University with naval architecture expertise. Ideal for a retired NA who wants to keep dabbling? The REQ...
Typing out loud...these sorts of thought experiments are always fun...the pressure from the bubbles at a particular depth on the hull would be...
How tall are you? Me standing in my hard-chined kayak with nice form stability would still be like a one-legged man in a bass fishing contest. So...
A boat that looks like this one fairly challenges you to believe it will be stable in the upright position. For that reason alone, I'd have hoped...
What exactly are your definitions of stiffness and strength? I don't want to make assumptions. Great data set, thanks. Echoes the data from the...
He said he was going to "the glass the whole thing inside and out", so it will be a sandwich construction as opposed to just taped seams. OK,...
Hmmm...really? The advantages of sandwich cores on strength is pretty well-known, no? Empirical data - on my strip-built kayak, prior to...
I'd just follow the plans, not worrying about the voids. The glass inside and out is what really gives the boat integrity. No need to over-glass...
I'm obviously interested in the topic. I come from an aircraft controls background. turns out maybe you can steal a system from an auto? I didn't...
Quick google, and there are a couple of systems you can buy right now it looks like. Electronic Command Steering by Hydro Marine, and ZF...
I am curious of the impact of vessels "flying in formation" nose to tail, and if when they get close enough the speed/length ratio is of the...
Thanks for the google tipper. Found some of what I was looking for.
Is the speed/length ratio of a barge train with pusher related to the length of the total ensemble, pusher, or individual barges? Seems to make...
If you have a smartphone with GPS, you can get an app that will record speed versus time. GPS speed is calculated via Doppler from the satellites,...
So what is a good reference for reading up on ram and ground effect?
The chord doesn't impact ground effect, the span does, so the canard's span is what is important. I agree that it does not look very pitch...
SKU = ?
Pretty big topic, lots of ways to slice it. Since your main goal is to get an 'A' in the course, don't let reality constrain you too much. Some...
Not sure if anyone is familiar, but the Defense Advanced Research Project Agency (DARPA) is running a series of design challenges in order to test...
Jumping into this discussion very late, but I'll quote this post from page 1. I'm an airplane guy, so to me it is all about lift. What is unique...
