摘要
本文研究内河顶推船倒车舵、导管桨后襟翼舵水动力性能。倒车舵、导管桨采用简化的模型。用它们的诱导速度场来体现对襟翼舵的干扰影响,襟翼舵采用存在分离涡的绕流模型计算其非线性升力。
This paper is concerned with the hydrodynamic performance of the backing rudder of the push boot and the back flap rudder of the nozzle propeller. Simplified models are adopted for the backing rudder and the nozzle propeller, whose inducing speed field represents the interference on the flap rudder. The non-linear lift of the flap rudder is worked out by the flow-around model of the separating swirl present.
