You can calculate hydrostatics in free programs like FreeShip. Create your hull there, set mass, and you can analyze buoyancy from different...
If the boat is solar powered, that means that it should carry quite a large solar panel. Monohull could be more efficient, but it needs to be wide...
Simulated H105, S3010, E205, E817, NACA63412. Method 3d panels, viscous. RN 100K,500K,1M,1.5M,2M,2.5M,3M. NCrit 2. AoA: -2 to 8. Type: Constant...
It is very nice method! Even without a laser, I can print a section on paper, glue it on aluminum sheet, cut and file to the required shape. Then...
Hi Skyak! Thanks a lot for your advice! It is very helpful! I had similar doubts regarding these anhedrals and winglets. I suspect it has...
I see most of famous and knowlegeable people are in Foiler Design thread. There are mostly discussed big foilers that have mechanical control:...
Hi Mikko, Thanks for pointing on S1223. I've found Selig book ( http://www.ae.illinois.edu/m-selig/uiuc_lsat/Low-Speed-Airfoil-Data-V1.pdf )....
There is no exact point. Well, the exact point will be when there is no displacement, but vessel still touches water. This is possible only in no...
I apologise if you already know it Modern windsurfer sails are usually fully battened (many have camber inducers -"cams") and buttons are bent...
>Q1. I would like to ask which is the computer program that you used to create your aerofoils? XFLR5 >Q2. Would you be able to label the...
I've read article "How Airplanes Fly: A Physical Description of Lift" http://www.aviation-history.com/theory/lift.htm It says that lower surface...
So, the main thing is not a difference in upper and lower lengths of a section, but rather is the camber? I felt this. The thin section (in my...
Thanks for explanation. What I do not understand with thin section is where they get lift power from? Thick section has longer upper curve and...
>2/ the airfoil generates true lift, not apparent lift >3/ the airfoil generates significantly less drag. I also read about that. But, and it is...
Hi. I am a newbie in aerodynamics. I am wandering about what benefits will give a changing a regular soft thin sail with a "thick" wing sail....
