Numerical Hydrodynamic Performance of the Stepped Planing Craft and Its Step Height Effect (RESEARCH NOTE)

One of the most efficient methods of reducing drag on planing craft is the use of transverse step on the bottom of a hull. Applying steps on the hull reduces the contact area with water and as a result, it reduces drag of the craft. Planing craft are able to have one or two transverse steps. In this paper, numerical hydrodynamic performance of the stepped planing craft and its step height effec...

Effective of Main Bearing Bolt Manufacturing Parameters on Functional Performance in High Speed Diesel Engine using Torque-Angle Method

In marine diesel engine, main bearing bolts (M18×1.5) withstand large tensile and cyclic loads to keep the crank shaft, bearing whit acceptable clearance and precision clamping force at high crank speed like 3100 rpm. In this research, the relationship between torque and clamp force, the friction coefficient, the effect of number of tightening and bearing conditions on the new manufactured bolt...

path following of a high speed planing boat based on gauss pseudospectral method

in this paper, the problem of optimal path following for a high speed planing boat is addressed. first, a nonlinear mathematical model of the boat’s dynamics is derived and then the serret-frenet frame is presented to facilitate the path following control design. to satisfy the constraints on the states and the input controls of the boat's nonlinear dynamics and minimize both the cross tracking...
