摘　　要：包含动力学和运动学特性的机载IMU数据对于飞行对准等惯性系统算法研究具有重要意义。基于人在回路仿真的思想,设计了一种可包含完整飞机模型,不需要设计特定的自动驾驶仪,来实现任意机动下机载惯性测量单元仿真的方案。给出了惯性测量单元仿真模型,设计了基于Simulink、AeroSim模块集及FlightGear模拟飞行软件的新方案,实现了一个机载惯性测量单元的仿真模型,该模型采用飞行摇杆,由人实现对飞机的控制和机动飞行。仿真结果表明,采用该仿真方案,避免了复杂的自动驾驶仪设计,可以得到机动飞行条件下的机载惯性测量单元仿真数据和导航参数基准数据,方案切实可行。The airborne IMU data including dynamic and kinematic characteristic has important significance for the algorithm research of inertial system, such as flight alignment. Based on the simulation idea of man-in-loop, a simulation method of airborne inertial measurement unit, which includes complete plane model and doesn＇t need to design specific autopilot, was presented. The simulation model of inertial measurement unit was given. A simulation proposal, which uses joystick to control the plane and complete flight maneuver, was designed and realized using Simulink, AeroSim and FlightGear. The simulations illustrate that the scheme, which can acquire any maneuver simulation data of airborne inertial measurement unit and standard navigation without autopilot design, is feasible.
