Ad Hoc i get it now! so there isn't any formula which i can use for the preliminary stages of the design to perform a rough check? Alik thanks...
Ad hoc i am accounting for that by using the empirical formula f_c=f_m+(2πVf_m^2)/g where f_m=1/(2.77√(H_s )) - f_m is the significant wave...
As for limits i am using the ISO motion sickness criteria (figures given in an earlier post). But i am not sure that this is sufficient. When i...
The deadrise angle at CG has to be at least 35 degrees to lower the acceleration levels within required limits
Mr Efficiency, i am aware of that. I intend to change those parameters when "optimizing" the design. This is just a feasibility study. But i want...
Speed - 40 knots Hs - 3.21ft Deadrise angle - 13 deg The reason why i want to know if its 1/10th or 1/100th is because i want to convert this...
Are you talking about the 1/10th highest accelerations? my average acceleration for a top speed of 40 knots is 5.33g. I attached the excel sheet i...
Is the formula given by the DNV for the average 1/10th or 1/100th highest accelerations. The formula is: a_CG=(k_h×g)/1650 (H_s/B_WL2...
Thanks very much Adhoc for clearing that out!!
I understand what you are saying. But what about the acceleration levels experienced by the craft for the persons on board? Lets say that the hull...
To help you understand better my problem i attached an excel sheet. I calculated the vertical accelerations for my entire speed range using the...
The average acceleration at CG is 1.68g (16.48m/s^2) and the average 1/10th is 5.55g (54.45m/s) which is quite different from your results....
on the subject, the formula given by the DNV is it for the 1/10th accelerations? I am using Savitsky and Brown's formula and the DNV to...
