摘　　要：飞行研究中心自主编队飞行项目的首次飞行试验阶段已经成功地证明了精度定位一架F/A-18飞机与第二架F/A-18飞机保持研究。混合式惯性导航系统(INS)和全球定位系统(GPS)测量已在空对空的遥测链路相连,用于计算相对位置估计。一种精密的研究编队自动驾驶仪的尾随飞机控制横向和垂直间距,而领先的飞机在自动驾驶仪控制下操纵。研究自动驾驶仪四个增益集被设计和飞行测试,稳态跟踪精度的设计要求在1个标准偏差10ft。性能也已被证明使用单轴和多轴输入,如阶跃命令和频率扫描。这份文章简要介绍了实验编队飞行系统,并讨论了已经飞行测试的导航,制导和控制算法。稳态跟踪飞行过程中编队的自动驾驶仪的飞行试验结果的概述。The first flight test phase of the flight research center autonomous formation flight project has successfully demonstrated precision autonomous station-keeping of an F/A-18 research airplane with a second F/A-18 airplane. Blended inertial navigation system （INS） and global positioning system （GPS） measurements have been communicated across an air-to- air telemetry link and used to compute relative-position estimation. A precision research formation autopilot onboard the trailing airplane controls lateral and vertical spacing while the leading airplane operates under autopilot control. Four research autopilot gain sets are designed and flight-tested, and the project design requirement of steady-state tracking accuracy within 1 standard deviation of 10 ft. Performance also has been demonstrated using single and multiple-axis inputs such as step commands and frequency sweeps. This article briefly describes the experimental formation flight systems employed and discusses the navigation, guidance, and control algorithms that have been flight-tested. An overview of the flight test results of the formation autopilot during steady-state tracking and maneuvering flight is presented.
