In order to carry out the unmanned airship system ground integration and flight simulation, the hardware and software of the hardware-in-the-loop(HIL) simulation platform was developed. It was based on real-time operating system(RTOS) VxWorks, Matlab/Simulink and real time workshop(RTW), FUTABA data acquisition system and three-dimensional visual system. The biggest innovation was the usage of the FUTABA remote control (RC) equipments and pulse width modulation(PWM)/RS-422 signal transform module, thus the visual sense and the control output of the pilot could be accessed to the simulation loop. The results show that man-in-the-loop flight simulation tests can verify the function of control mode switching and the effects of attitude and track control. The tests also improve the pilot-s proficiency in controlling this type of the unmanned airship directly to land steady in case of emergency.
