摘　　要：为了提高某型无人机(UAV)的航时,螺旋桨应该具有高的巡航效率、足够的爬升拉力。利用高效率螺旋桨设计方法设计了某型无人机的两叶木质螺旋桨,获得了螺旋桨的弦长和桨叶角分布,基于片条理论计算了螺旋桨的气动性能,进行了螺旋桨的地面静态试验。结果表明:螺旋桨性能计算结果与台架试验结果具有较好的一致性,螺旋桨性能计算的巡航效率为83.81%,巡航拉力为222.95 N。设计的两叶木质螺旋桨可以满足某型无人机的巡航效率与拉力需求。In order to improve the endurance of a type of unmanned aerial vehicle(UAV), a propeller of high cruising efficiency and sufficient climbing thrust should be required. The two-blade wooden propeller of a type of UAV was designed by the high efficiency propeller design method. The chord length and blade angle distribution of the propeller were obtained. The aerodynamic performance of the propeller was calculated based on the strip theory. Ground static tests of propeller were carried out. The results of the performance calculation of the propeller were in good agreement with the results of the ground static tests. The calculated cruising efficiency was 83.81%, and the calculated cruising thrust was 222.95 N. The two-blade wooden propeller can meet the requirements of the cruising thrust and efficiency of a type of UAV.
