本文利用文献[1]中已得的抛出角近似公式,提出了抛掷型风扇的设计与计算方法。指出径向叶片有较强的适应性,特征系数 MI=L_1/(Rcosδ)_1 不但可以用来决定叶片的结构参数且对运动学参数有较强的控制作用,判别式ω~2(fr_0+I_1)大于 g/(com(?)) 的10倍时可不计重力。大量的计算证明本文提供的计算方法是有足够的精度的。
In this paper, the throwing angle approximation formula obtained in [1] is used to design and calculate the throwing fan. It is pointed out that the radial blade has strong adaptability. The characteristic coefficient MI = L_1 / (Rcosδ) _1 can not only be used to determine the structural parameters of the blade but also control the kinematic parameters strongly. The discriminant ω ~ 2 (fr_0 + I_1) is greater than g / (com (?)) 10 times the weight can be ignored. A large number of calculations prove that the calculation method provided in this paper is sufficient accuracy.
