The invention discloses a resistance reduction device for controlling shock wave boundary layer interference through plasma excitation. The resistance reduction device comprises a first flat plate, a second flat plate and a discharge electrode. The first flat plate is fixedly connected with the second flat plate, and a transition tape is arranged at one end of the first flat plate away from the joint of the first flat plate and the second flat plate; an included angle alpha is formed between the plane of the first flat plate and the plane of the second flat plate; a plurality of cylindrical holes are formed in the first flat plate and are used for placing discharge electrodes; wherein every two cylindrical holes form a group and are respectively used for placing positive and negative discharge electrodes, and each group of cylindrical holes are arranged in a staggered array; the number of the cylindrical holes is 2 * N * (2M + 1), and the cylindrical holes are sequentially arranged on the first flat plate in the direction from the transition tape to the second flat plate. According to the array type plasma exciters arranged in a staggered mode, under the condition that the same energy is consumed, a better flow control effect can be achieved, friction resistance can be remarkably reduced, and piezoresistance can be further reduced.

    本发明公开了一种等离子体激励控制激波边界层干扰的减阻装置,包括:第一平板、第二平板与放电电极;第一平板与第二平板固定连接,第一平板在远离其与第二平板连接处的一端,设置有转捩带;且第一平板所在的平面与第二平板所在的平面存在夹角α;第一平板上设置有多个圆柱孔,圆柱孔用于放置放电电极;其中,圆柱孔每两个形成一组,分别用于放置正负放电电极,每组圆柱孔呈交错阵列设置;圆柱孔设置有2*N*(2M+1)个,并在第一平板上按照从转捩带往第二平板的方向依次排布。本发明通过提供一种交错式布局的阵列式等离子体激励器,在消耗同样能量的情况下,可以实现更好的流动控制效果,可以显著降低摩擦阻力,压阻也能进一步降低。
