• 中文摘要： 本文利用升力面理論來處理對轉螺槳的流體動力問題，整個系統的壓力場與速度勢可由各個螺槳之分量相加而得到，由每個螺槳之運動邊界條件，吾人可以建立一積分方程式系統以決定螺槳葉片上之負荷分佈，該積分方程式將考慮前、後螺槳互相誘導之影響，螺槳之流體動力螺距角與葉片上之負荷將由疊代方式計算。 單一螺槳之誘導速度場、對轉螺槳系統中螺槳之推力及扭矩係數將被計算並與試驗資料比較。前、後螺槳間之互相誘導速度及每個螺槳葉片上之壓力分佈亦將被計算。
• 英文摘要： In this paper the linearized lifting surface theory for propellers is used for the treatment of thehydrodynamic problem of contrarotating propellers. The pressure field and the velocity potential of thewhole system are obtained by superposition of the components for each propeller. From the kinematicboundary condition on blades of both propellers, a system of integral equations for the determination ofthe loading distributions on the blades is derived. In the integral equations the mutual inductions betweenthe forward and the aft propellers are accounted for. The hydrodynamic pitches together with the bladeloadings are determined iteratively. The single propeller induced velocity field, the thrust and torque coefficients of both fore and aftpropellers of contrarotating system will be calculated and compared with experimental data. The mutualinduction between fore and aft propellers and the pressure distribution on blades of both propellers is alsocomputed.
