Abstract: Hardware-in-the-loop simulation is an effective way and experimental method to evaluate and verify the performance of the aircraft system. To satisfy the requirements of real-time, scalability, high reliability simulation of a certain aircraft control system, a new design of low-cost hardware-in-the-loop real-time scene simulation system consisted of IPC, DSP, three-axis turntable, steering engine and visual simulation computer was put forward. Real-time simulation system software composed by flight control simulation module, aircraft movement simulation module and scene simulation module was implemented, and it resolved the difficulties in real-time, data synchronization, multiple node communication of simulation system. Comparison with flight test results shows that the simulation system satisfied the requirements in real-time and reliability, and it is valuable for aircraft design and research.

Key words: hardware-in-the-loop simulation, aircraft, real-time, scene simulation, data synchronization
