随着战场环境和作战任务日益复杂, 单机型作战会有一定的局限性, 为实现直升机和无人机混合编队作战, 需开展直升机和无人机协同试验技术研究, 以提供理论基础和试验数据支撑。以直升机与无人机协同作战任务为牵引, 以验证直升机与无人机Ⅱ级协同能力为目标, 构建直升机和无人机中继通信试飞剖面, 自顶向下对试飞剖面进行任务分解和试验点分解, 分析中继通信试验过程中的关键技术问题, 最后选取典型试验场景对直升机和无人机中继通信进行试飞验证。直升机和地面指挥所通过无人机中继实现了信息交换, 通信中继功能性能满足作战使用要求。完成了直升机和无人机Ⅱ级协同试飞演示验证, 对后续Ⅲ级协同试飞具有指导和借鉴作用。

With the increasing of complexity of the battlefield environment and fight tasks, operations conducted by either the helicopter or Unmanned Aerial Vehicle (UAV) solely have its own limitations. In order to realize the mixed-formation operation of helicopters and UAVs, it is necessary to study the helicopter-UAV cooperative test technology, so as to provide a theoretical basis and experimental data support. Based on the cooperative combat tasks of helicopters and UAVs, and taking the verification of the second-stage helicopter-UAV cooperative capability as the objective, we constructed the helicopter-UAV relay communication profile. From the top to the bottom, the profile was decomposed by tasks and test points. The key technologies during the relay-communication testing process were analyzed. At last, typical experimental scenes were chosen to carry out the test flight and verify the helicopter-UAV relay communication. The information exchange between the helicopter and the ground command center was realized through UAV communication relay. The performance of the communication relay met the operational requirements. The flight test verification of the second-stage cooperation of helicopters with UAVs was implemented, which can be taken as a reference for the subsequent third-stage test flights in the future.
