摘　　要：针对国内某型飞机失速尾旋模拟训练需求,研制了某型飞机失速尾旋模拟训练系统。系统由多通道球幕视景系统、半实物仿真座舱以及操纵力控制加载系统等组成,采用分布式仿真技术,构建了逼真的人在回路模拟训练环境。针对失速尾旋仿真,对多源气动数据进行了综合处理,构建了大迎角非定常气动力模型,采用大载荷数字电动控制加载技术进行失速尾旋交变力和抖振特性仿真,实现了人在回路的失速尾旋模拟训练。Aiming at the domestic aircraft stall spin simulation training need, a stall spin simulation training system is developed. The training system consists of the multi-channel dome visual system, the semi-physical simulation cockpit and the maneuvering force control loading system, etc. Distributed simulation technology is used to develop a realistic man-in-the-loop simulation training environment. For the stall spin simulation, the multi-source aerodynamic data is processed comprehensively, and an unsteady aerodynamic model at high angle of attack(AOA) is constructed, and the heavy-load digital electric control loading technology is used to realize the simulation of stall spin alternating force and jitter characteristics of steering, which realizes the stall spin simulation training of man-in-the-loop.
