摘要
为研究翼型加厚对桨扇性能的影响,通过两种不同的加厚方式对桨扇翼型进行加厚,采用NUMECA软件对加厚前后的对转桨扇进行三维流场数值模拟,对比加厚前后对转桨扇的性能变化.结果表明:在同一飞行状态下,无论是翼型整体加厚,还是只改变翼型最大厚度,对转桨扇的性能都会下降;相比于整体加厚,只改变最大厚度则性能下降得更多;在不同来流攻角条件下,攻角越大,加厚前后的对转桨扇性能差值越大.
Abstract
In order to study the influence of airfoil thickening on the performance of propeller fan,two different thickening methods were adopted to thicken the propeller fan.NUMECA software was applied to simulate the three-dimensional flow field of the rotor fan before and after thickening,and the performance changes of the rotor fan before and after thickening were compared.The results show that the performance of rotor fan,under the same flight condition,will be decreased whether by overall airfoil thickening or by only changing the maximum airfoil thickness.Compared with the overall thickening,the performance of rotor fan will be decreased more when only changing the maximum airfoil thickness.Under the condition of different angle of attack,the larger the angle of attack,the greater the performance difference of the opposite rotor fan before and after thickening.
