A tandem thrust reverser grid device is formed by arranging a plurality of tandem thrust reverser grid units in the circumferential direction, and each of the plurality of tandem thrust reverser grid units comprises a plurality of grid inlet rib plates located on the inlet side of the tandem thrust reverser grid units, and a plurality of grid outlet rib plates located on the outlet side of the tandem thrust reverser grid units. The plurality of grid inlet rib plates are located on the inlet side of the tandem thrust reverser grid unit, the plurality of grid outlet rib plates are located on the outlet side of the tandem thrust reverser grid unit, the outlet end faces of the plurality of grid inlet rib plates and the inlet end faces of the plurality of grid outlet rib plates are spaced in the flow channel height direction, and the width exists in the reference line direction. By means of the tandem reverse thrust grille device, the boundary layer separation phenomenon during airflow deflection can be improved.
一种串列反推格栅装置,由多个串列反推格栅单元沿圆周方向排列而成,上述多个串列反推格栅单元中的每一个包括:多个格栅入口肋板,上述多个格栅入口肋板位于上述串列反推格栅单元的入口侧;以及多个格栅出口肋板,上述多个格栅出口肋板位于上述串列反推格栅单元的出口侧,上述多个格栅入口肋板的出口端面与上述多个格栅出口肋板的入口端面在流道高度方向上存在间隔,在基准线方向上存在宽度。通过上述串列反推格栅装置,能够改善气流偏转时的附面层分离现象。
