The invention belongs to the technical field of vent cover design, and particularly relates to a vent cover which is provided with a plurality of hexagonal grid holes. And the edge of each hexagonal grid hole is internally connected to a circle with a fixed diameter. According to the vent cover, an upper grid hole is a hexagon internally connected to a fixed-diameter circle; each hexagonal grid hole occupies an area defined by a circle with a fixed diameter; compared with rhombic grid holes, the hexagonal grid holes have the advantages that the ventilation area is large, the ventilation efficiency is high, the requirement for ventilation capacity can be met through the relatively small number of grid holes, the number of the grid holes can be reduced, the size of the whole vent cover can be reduced, and therefore the overall mass of the vent cover can be reduced. Besides, in the vent cover, the edges of the hexagonal grid holes are internally connected to the circle with the fixed diameter, a good stealth effect can be achieved, and the requirement of an airplane for stealth performance is met.
本申请属于通气口盖设计技术领域,具体涉及一种通气口盖,该通气口盖上开设有多个六边形格栅孔;各个六边形格栅孔的边缘内接于固定直径的圆。该通气口盖,其上格栅孔为内接于固定直径圆的六边形,单个六边形格栅孔占据一个固定直径圆围成的区域,相较于菱形格栅孔具有较大的通气面积,通气效率较高,可以以相对较少的格栅孔满足通气量的要求,利于减少格栅孔的数量,以及减少整个通气口盖的尺寸,从而能够降低通气口盖整体的质量;此外,该通气口盖中,其上六边形格栅孔的边缘内接于固定直径的圆可取得较好的隐身效果,满足飞机对隐身性能的要求。
