近日，成都联合飞机自主研发的TD550D无人直升机系统正式获得中国民用航空局颁发的型号合格证（TC），成为全国首款通过型号合格审定的无人直升机系统，标志着我国民用无人直升机产业发展迈入新阶段。
中国无人机在全球范围内率先探索出了一条适航之路，为低空经济发展提供了宝贵的经验和范例。以安全保障为基础，TD550无人直升机拥有“大载重、长航时、高原性能强”等三大核心优势，自主程度高，适应高原、海岛等复杂环境，凭借6500米高原作业能力、200公斤载重优势及多任务模块兼容性，形成应急救援、消防灭火、智慧物流等全行业应用矩阵，帮助传统产业提质增效，拓展低空经济应用边界。
市场机会方面，TD550机身采用碳纤维、铝合金等高强度轻质材料，相关材料供应商如$中航高科(sh600862)$、$光威复材(sz300699)$等将受益。另外，推动无人机适航认证标准化，龙头$中无人机(sh688297)$等将受益于行业扩容。
