Simulation of True Airspeed Calculating Machine for Bombing Gun-sight

应用基于动态基点测量的数字式自适应补偿技术,消除了各种干扰因素对供电电压的影响,使真空速的数字量驱动信号自动适应供电电压的变化,实现了轰炸瞄准具真空速传感装置的精确模拟;用表征真空速的数字量驱动信号,取代原实装设备的模拟量电压驱动信号供给计算机构,并使仿真信号与实装模拟信号兼容。仿真结果和实际应用表明,该系统具有仿真精度高、稳定性好等特点,能广泛地应用于领航轰炸模拟器的瞄准具上。

Because the adaptive compensation technology of dynamic base-point measure is adopted in this paper, all the influences that disturb power supply could be eliminated, the digital drive signal of true airspeed automatically change with power supply, and the accurate simulation of sensor devices are realized for true airspeed of bombing gun-sight. Although digital drive signal of true airspeed supersede analog drive signal of the real bombing gun-sight to calculating machine, the simulation signal is compatibility with analog signal. The simulation results and application in practice show that the system has characteristics of high precision and good stability. It could be widely applied to gun-sight of pilot bombing simulator.
