  4. The running condition would be deteriorated and at last the parts of the engine would be damaged if the revolution were reduced too low. the propeller must be redesigned or be modified in this situation. people usually modify the propeller rather than change the propeller because it will be more easily and economical

    此時若要更換新的必然造成經濟上過重的負擔,較方便可行的方法是對原來的採取切修改的方法,減少的直徑、盤面積或距,使的扭矩減小,變「輕」 。
  5. The loading of the engine will be lowed and the revolution will be raised at the same time. it is effective when the propeller trailing edge cutting is performed outer radius

    因為在0 . 5r以外作隨切割方式有較佳的效果,所以本文決定採用在外半徑處作非線性的隨切割方式。
  6. The primary purpose of this paper is how to solve the overloaded propeller ' s condition. the style of propeller trailing edge cutting and shave on the pressure surface is adopted. the propeller ' s actual effect pitch will be reduced which cause the propeller ' s torque down

    本文主要是考慮出現負荷過重時如何處理的問題,所以採用葉隨切割並在葉面處將翼型修順的方式,實質上是切割后導致實效距的減小,從而使吸收的轉矩降低來達到主機負荷降低的目的。
  7. 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水動力性能,表面及尾渦面離散為四形雙曲面元,每個面元上布置等強度源匯和偶極子分佈.對于大側斜而言,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的計算和收斂問題.葉隨處通過迭代實現非線性等壓庫塔條件
  8. And the last, some sea trial results show that the match among the main engine and propeller is slightly heavy for the real vessel construction. although the reasons are very complex, most of them can be resolved by the method of propeller trailing edge modification. because of lack of guidance in theory, the actual quantities of modification were very difficult to decided and lots of quarrels may be raised between the shipyard and the owner before

    最後,針對實際船舶建造過程中,部分船舶的試航結果表現出來的機匹配稍重問題,雖原因比較復雜,但絕大部分可以採用修正的方法解決,因為沒有理論數據給予指導,很容易引起爭議,在具體修正的數量上較難卻定,其修正後的工況更難準確預報。
