A study of high efficiency wing considering its transient fluid-dynamic characteristics

对过渡状态下的机翼性能进行了基础性研究，如船舶的舵或尾翼。通过在机翼上施加驼峰或一些附加部件来提高机翼的稳态性能，研究了过渡条件下的机翼性能以及机翼部件对过渡状态的影响。在水流中运动的机翼上的作用力已在实验测量中测量过。对类似条件下的机翼绕流也进行了数值模拟。在此基础上，研究了机翼性能及其影响因素的变化规律。

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.
