摘要： A method for reducing a wave making resistance caused by a transom stem of a displacement ship that has a transom stem and voyages at a design speed corresponding to Froude's number of 0.2 - 0.4, the transom stem having a shape of a stern bottom profile, in which an inflection point is provided at a predetermined distance forward of a stern end, a slow flow region is formed forwardly of the inflection point and an accelerated flow region is formed rearwardly of the inflection point to make flow fields forward and rearward of the inflection point differ from each other, and a lower end of the stern end is positioned in the vicinity of a designed draught, thereby reducing the wave making resistance.

摘要： Force balance and moment balance associated with thrust of air and water craft equipped with thrust generators are preset in view of non-linear characteristics and dynamic characteristics of thrust generators. A performance index for minimizing thrusts generated by the thrust generators is defined. Using the balance as restricting condition, propeller thrusts of the thrust generators and rudder angles and changing speeds of rudders that minimize the performance index are calculated.
