@Howlandwoodworks, Now your model is a work of art. I am rather ashamed to have presented my work. I can only console myself as a first attempt I...
Here is a hull I put together to check for design flaws (and yes it failed): [ATTACH] [ATTACH] [ATTACH] I am trying to develop lines for the...
Hi Steve, I note there was a previous discussion on hyroplane sponson design (with a design concept): Sponson Design...
Hi, Someone may have exactly what you want, but if not, then you will need to design your own. You could try trial and error with paper, scissors...
Hi @WhiteRabbet, When it comes to the time that you commit to spending your dollars, I think it would be a very good idea to confirm the...
Hi @WhiteRabbet, A Tc of 4ft is perfect with regard to typical hull coefficients. The mid-section hull bottom design pressures are now: 26.4 kPa...
Hi @WhiteRabbet, Not clear if the measurement is vertical or slope, Tc is a vertical measurement....
Hi @WhiteRabbet, 5'3" is what I was looking for, 8'3" was an obvious typo. Okay: LOA 16.77m LWL 14.17m BOA 4.58m BWL 4.29m TC 1.60m Disp...
Hi @WhiteRabbet, The TC is too large for 28 ton or the 28 ton is too low, and is that a short or long ton? I work in metric tonnes. Tc is the...
Hi @Bishiba, Here are a set of simplified (i.e. does not model stall) equations for a NACA 0012 aerofoil used to model a wing (excluding skin and...
Here is a skin of frame I saved from the Internet a long time ago: [ATTACH] Pretty cool really, AlanX
Stress! What else?
The following webpage discusses this problem: Membranes | Engineering Library...
@Tanal, I don't disagree, I am answering the @sun's question. AlanX
If we step back, we have a hull function Fhull(x,y,z) and a Fwaterplane (x,y,z). The water plane factors A, B, C and D can be calculated for a...
@TANSL and @gonzo, If you are a programmer then x=x-f(x)/f'(x) makes perfect sense. But it can be written as: xnew=xold-f(xold)/f'(xold) and if...
Check out FAO: http://www.fao.org/3/a-ak803e.pdf , it is 15 m or 21 m, not 33 m.
Hi @sun, Although you can solve analytically the intersection for my hull equation as it is a quadratic, you will not be able to solve a higher...
I have had a think about this and here is an initial case: A very simple hull can be defined as: y=+/-0.5*Beam*(1-(z/Depth)^2)*(1-4*(x/Length)^2)...
Hi @philSweet, Your document is a bit of a find. My current process is to: Import an offset table Interpolate (smoothed) chine lines for...
