A fundamental study to enhance performance of a wing under transitional condition, such as a rudder or a fin of a ship, has been conducted. By applying humps or some additional parts on wing, which enhance the wing performance in steady state, wing performance under transitional conditions and its variation given by the parts on the wing have been investigated. Forces acting on a wing that moved in a water flow have been measured in experimental measurements. Numerical simulations of flow around a wing in the similar conditions have also been conducted. Based on these results, variations of wing performance and their elements have been investigated.

已经进行了一项基础研究，以增强过渡条件下机翼（例如船的舵或鳍）的性能。通过在机翼上应用驼峰或一些附加部件来增强稳定状态下的机翼性能，研究了过渡条件下的机翼性能及其由机翼上的部件引起的变化。实验测量中测量了作用在在水流中移动的机翼上的力。还对类似条件下机翼周围的流动进行了数值模拟。基于这些结果，对机翼性能及其要素的变化进行了研究。
