摘要
本文给出一组开孔率为0～30.19％的船用平板舵的水动力性能试验曲线,分析了开孔舵的原理,并对开孔翼绕流理论计算中的透气系数(Porosity Co-efficient)进行了分析,得到了开孔平板的透气系数的具体数值,使开孔舵的升力特性的理论估算有了可能。
This paper gives a set of test curves of hydrodynamic performance of the plate rudder with porosity from 0 to 30.19％. The principle of the porous rudder of ancient Chinese ships is andyzed and the poroaity coefficiets in the calculation of the flow around the porous wing are studied. Some numerical figures of the porosity coefficients for the porosity plate are obtained, thus it is possible to estimate the lift characteristics of porous rudder theoretically.
