  1. 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

    本文要是考慮出現負荷過重時如何處理的問題,所以採用隨邊切割並在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機負荷降低的目的。
  2. The computer program has following advantage : the solution of main blade is by iterative scheme in time domain, the kutta condition is used by explicit equal pressure condition, the jacobian matrix which can reflect the influence on the difference between the upper and lower surface at trailing edge by dipole is calculated in each iterative procedure, in order to improve the convergence of iteration

    本文編制的非定常性能預報程序是針對在時域中迭代求解的, kutta條件採用的是顯式的等壓條件,求解中為了提高迭代的收斂性,在每次迭代中都重新計算反映偶極子強度對尾緣處上下表面壓力差影響的jacobi矩陣。
