【摘要】 舵法向力可视作舵对来流的响应。船、浆的存在仅改变舵上来流的大小和方向而影响舵法向力。本文以试验研究的方法探讨了船、桨两者对来流的作用规律,提出了肥大型船在不同漂角时计算舵法向力的公式: C_N=[1+τ(β)]~2k_O(2π)/(1+2/λ)sin[δ-δ_O(β)] 并对船舶后体形状的影响作了探讨。更多还原

【Abstract】 The normal force of a rudder can be looked upon as a kind of response to flow speed. The ship and its propeller affect the normal torte only by changing the magnitude and direction of the flow speed. This paper presents a research into the law acting on the flow by the ship and its propeller. An experimental formula for calculating the normal force of the rudder on large full ships at different drift angles has been derived as follows: C_N（1+τ）²K₀（2π）/（1+2/λ）sin（δ-δ₀） The effect of the shape of afthody upon the normal force of the rudder has also been investigated.更多还原
