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.关键词
