摘要
文章首先基于雷诺相似理论,在地面螺旋桨实验平台上开展ARA-D翼型螺旋桨微秒脉冲等离子体增效三维实验,结果表明,等离子体对螺旋桨拉力增效效果随着脉冲频率增加而减弱,而螺旋桨转矩受等离子体影响随拉力增效效果增加而减弱,拉力、效率最大增幅分别达到10.79%、11.56%。而后基于雷诺相似理论及叶素理论,在低湍流度风洞开展S1223翼型螺旋桨叶素微秒脉冲等离子体增效二维实验,结果表明等离子体激励提高了翼型各叶素拉力,其中根部与尖部叶素表现尤为明显。二维实验结果可为三维实验激励器展向排布方案提供理论依据。2种实验结果均表明,等离子体射流可以有效抑制翼型表面流动分离。
Based on the Reynolds-Similarity Theory,an experiment is carried out for the ARA-D propellerairfoil to study the microsecond pulse plasma flow control supported by the ground test platform for thepropeller.It is found that the synergy of the thrust decreases with the increase of the actuation frequency.Thethrust increases by10.79%and the efficiency increases by11.56%.Based on the Reynolds-Similarity Theoryand the Blade Element Theory,an experiment is carried out for the S1223propeller airfoil to study theenhancement performance of the microsecond pulse plasma flow control supported by the low-turbulence windtunnel.It is found that the plasma actuation improves the thrust of the blade elements,especially in the root andthe tip,and the result provides a theoretical basis for the actuator distribution in the span direction in ARA-Dexperiments.The results of both experiments show that the plasma jet restrains the boundary layer separation onthe airfoil surface effectively.
