flexure element-
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Ould have good flexibility and flexing fatigue - resistance performance ; it should be anti - aging, oil - resistant and wear - resistant ; on the inner side of the back there should be point angel grooves of appropriate sizes made not only to meet technical de mands but also for purpose to improve the anti - wear performance, meanwhile, part of the noises shall be eliminated due to the escaping of the detained air between the be
同步帶的背部用以粘結包覆抗拉元件，應有良好的柔韌性和耐曲撓疲勞性能，不易老化，耐油性好，耐磨損，在帶背的內表面開有適當大小的尖角凹槽，除因工藝要求外，還能改善帶的曲撓疲勞性能，同時在運轉過程中使帶與輪間的截流空氣逸出，以消除部分噪音。
