The propller may be a good choice. I will try to buy one. The hole thing is about the knowledge of hydrodynamics. Quite interesting. But I would...
It seems quite simple. But... I finally got what you mean. The water jet will not work well when underwater. The performance is bad. But, I saw...
I recently got a small pump-jet, or water pump, for ship models. It's just like those in big ships know as the water jets or so. But...
That would a big one...
I went to a engin supplier yesterday. They sell big engins such as 130hp and more. No small engins. I sent e-mails to some of the engin company on...
The boat now is still on the design. I think some $30k is the most. Maybe 20k for the engins and propellers and 10k for the hull.. I can finish...
Thanks. I am still working on it... I just need to try a different way.. But it's really hard to get a pump. I'd asked some factories recently,...
And to masalai... I met another shipowner yesterday. He had built a super fast boat using jet pump. He just bought a jet ski form one of the...
Thank for rasorinc. 2si may be a good choice... I'am trying to get contact and ask about some information...
It seems that a 1400cc engin with a pump is OK. But as I said, they sell the whole boat, not a pump. It's not available... Thank you... by the way..
Thank you for your help. Speedboat. In fact, I'd prefer some new integral and standard equipment for this boat. The boat will use for quit a...
:DAnd... I also want to find a suitable electrical ducted thruster for my diving tool. 5-20kg thrust and work in lake fresh water. Is...
I am now designing my new boat now. The boat maybe 5-6 meter length. I prefer to use a jet propeller. It is predicted that the boat may need at...
Oh, thanks. I noticed that. It's very helpful. I can calculate the area of each section. But sometimes, area moment of each section is...
I wonder: Can maxsurf softwares be use to calculate Bojean's curves? Sometimes, Bojean's curves is needed in Ship design...
A U series sub used in WW-II may be a good example.
In my opinion, CFD need huge computers... Fluent V6.x maybe a good choice. I've read many papers about that from hydrofoils to very fast ships...
And some Japanese researchers had finished some work on a hydrofoil submarine. Er.... I think I've read some about a AD report about a...
Hi. I've read this about a submersible hydrofoil boat. http://www.hyper-sub.com/ Their job may be helpful.
We suggest some bigger model if the resistance is the main problem.
