  3. Being one of the new types of moderate skewed propeller with small area - ratio, the hudong type propeller is with virtues of high efficiency, low vibration and light in weight

    Hudong型槳是滬東廠近年來借鑒國內外先進的螺旋槳設計技術，結合工廠設計與建造的實際船舶產品開發的中等側斜度、小盤面比螺旋槳。
  4. The control algorithms of both traditional and intelligent main - engine speed regulator are emphatically discussed in the thesis. the author established an simplified integrated mathematical model for marine main diesel engine, screw propeller and axis series with the mother type of large low speed diesel man b & w. the digital simulations for pi speed regulator are completed

    本文討論了主機速度控制的兩種實現方法；論文以實船應用的manb & w大型低速柴油機為母型，建立了柴油主機、螺旋槳、軸系一體化的簡化數學模型，並對常規柴油主機pi調速系統進行了數字模擬。
  5. The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller. the surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution. for highly skewed propeller, the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface, which result easily in incorrect calculation results of velovity on blade surface, even in iteration divergence and calculation failure. a “ non - conventional grid ” is developed to acoid these problems. this grid can effectively solve the problem of the calculation and convergence for highly skewed propeller. the non - linear kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure. by sample calculating, the obtained results are satisfied the experimental data

    採用面元法預報大側斜螺旋槳水動力性能，螺旋槳表面及尾渦面離散為四邊形雙曲面元，每個面元上布置等強度源匯和偶極子分佈.對于大側斜螺旋槳而言，槳葉表面採用常規的等半徑網格劃分方法在近葉梢處將導致大展弦比、大側斜和扭曲面元，這容易使槳葉表面速度的計算結果不正確，甚至會導致迭代過程發散及計算失敗.文中建立了一種「非常規網格」劃分方法，能有效地解決大側斜螺旋槳的計算和收斂問題.槳葉隨邊處通過迭代實現非線性等壓庫塔條件
