hi everyone! I am now designing propeller for my high speed craft. Via the internet, I found some documents about KCA propeller series....
that are exact number. b DemiHull = 2,7 m distance 2 DemiHull = 1m draft = 1,2 m D = 2 m CB DemiHull = 0,66 This catamaran use main engine...
yes, my circumstance is quite special. in fact, this catamaran are being designed by other company, but They employ my company to design propeller...
thanks Ad Hoc! I have a problem with calculating its resistance. have you got great idea?
thanks Leo Lazauskas for helping! because I do not have a lot of time for this project, I must find a simple method for calculating. I think,...
right, it is the strange hull. this catamaran is the working boat whose speed is about 8 knots. in my opinion, with low speed, hull is not the...
hi everybody! i am calculating propeller of a low speed catamaran but all methods which i have don't suit. can you give me advice? thank you so...
thank guys so much! Your documents Which are very useful made me more confident in choosing propulsion system for my boat. In my book, there are...
hi guys! i have a engine (257kW, 3300 rpm) and a WaterJet (HJ274). Now, i have to check them whether suitable with high speed vessel or not, but...
hi everybody.i am studying about designing propller. but i have much problems. what is slip? how does it is caculated ( fomular for this)? thanks.
you can determine diameter D according to fomular : (n)^(1/2)*D=11,8(T)^(1/4) or (n)^(1/2)*D=13*(Ps/vs)^(1/4) n: revolution of propeller D:...
i changed it to english. you can give me your idea what i can refer to develop my programe. thanks!
which conditions? Re? with z=3,4,5 it's reliable but z=2,6,7 it is not reliable. but it's acceptable. this's a programe what calculate...
why don't you try to use KT-KQ-J diagram? it is easier Bp-denta. i have polynomial representaion of the data of KT-KQ-J. if you'd like, i will...
i read it. that's very interesting.thanks! Çemberci : i have a question: which way to calculate CF? (ITTC1957?) and my boat Fn >0.475. which way...
i am designing propeller for fishboat but i haven't found method of predicting resistance for it. who can share it for me? (the best is regression...
