Abstract: A duct cover (12) for use with a duct (4) within a vehicle, the duct cover (12) operative for directing a fluid flow. The duct cover being further operative for minimizing the entrance of foreign object debris into the duct (4). The duct cover (12) has a flow directing honeycomb portion (16) for conducting the passing fluid flow in a preferred direction. The flow directing honeycomb (16) comprises an array of continuous, polygon shaped open cells (20) which are biased with respect to the initial fluid flow direction. The periphery (17) of the flow directing honeycomb (12) is rigidized to stiffen the same for minimizing the displacements thereof. The rigidity is provided by a framing member comprising upper and lower skin structures (28, 29) affixed to a core material (30). The framing member is preferably adhesively bonded to the flow directing honeycomb (16) by means of a foaming adhesive (36) and a barrier member (38). The barrier member (38) is operative for minimizing the expansion of the foaming adhesive (36) into the open cells (20) of the honeycomb (16). In order to improve the low observability characteristics of the structure, the cells (20) of the flow directing honeycomb (16) are preferably coated with a radar absorbent material, such as carbon, which acts to minimize the amount of electromagnetic energy that is reflected therefrom.

Abstract translation: 一种与车辆内的管道（4）一起使用的管道盖（12），所述管道盖（12）用于引导流体流动。 管道盖还可操作以最小化异物残留物进入管道（4）的入口。 管道盖（12）具有导流蜂窝部分（16），用于在优选的方向上传导通过的流体流。 导流蜂窝（16）包括相对于初始流体流动方向偏置的连续多边形开放单元（20）的阵列。 导流蜂窝体（12）的周边（17）被硬化以使其加强，以使其移动最小化。 刚性由包括固定在芯材（30）上的上，下皮肤结构（28,29）的框架构件提供。 框架构件优选通过发泡粘合剂（36）和阻挡构件（38）粘合地结合到导流蜂窝体（16）。 阻挡构件（38）用于最小化发泡粘合剂（36）到蜂窝（16）的开孔（20）中的膨胀。 为了改善结构的低观察性特征，导流蜂窝（16）的电池（20）优选地涂覆有诸如碳的雷达吸收材料，其用于最小化被反射的电磁能量的量 由此。
