The invention discloses an empennage structure suitable for a built-in link antenna of a high-speed fixed-wing target drone, the empennage structure comprises an empennage inner section foam sandwich skin, an antenna wire passing hole and a link antenna body, one end of the empennage inner section foam sandwich skin is provided with a root rib, the antenna wire passing hole is arranged in the root rib, and the antenna wire passing hole is arranged in the link antenna body. A cross beam is installed in the empennage inner section foam sandwich skin, a carbon tube penetrating through the empennage inner section foam sandwich skin is arranged in the antenna wire passing hole, the carbon tube is located in the middle of the cross beam, and an empennage outer section foam sandwich skin is installed on one side of the empennage inner section foam sandwich skin; according to the device, a link antenna feeder penetrates through a carbon tube in an antenna wire passing hole and extends out of the antenna wire passing hole, the link antenna body is prevented from being installed outside an aircraft body through the structure, aerodynamic resistance can be reduced, and flight stability is improved.
本发明公开了一种适用于高速固定翼靶机内置链路天线的尾翼结构,包括尾翼内段泡沫夹心蒙皮、天线过线孔和链路天线本体,所述尾翼内段泡沫夹心蒙皮的一端安装有根肋,且根肋的内部开设有天线过线孔,所述尾翼内段泡沫夹心蒙皮的内部安装有横梁,所述天线过线孔内部设置有贯穿尾翼内段泡沫夹心蒙皮的碳管,且碳管位于横梁的中间位置处,所述尾翼内段泡沫夹心蒙皮的一侧安装有尾翼外段泡沫夹心蒙皮,且尾翼外段泡沫夹心蒙皮的内部设置有空槽,所述空槽的内部通过粘结剂设置有泡沫层,该装置将链路天线馈线贯穿天线过线孔内碳管并从天线过线孔延出,该结构避免了链路天线本体安装在机体外,可减小气动阻力,提高飞行稳定性。
