构建了一套通用的米-171直升机AΠ-34Б自动驾驶仪模拟式和数字式半实物仿真试验系统,研制了模拟式和数字式组合接口的航电信号仿真器,建立了米-171直升机非线性飞行动力学数学模型,搭建了模拟式和数字式飞行控制系统的地面半实物仿真试验环境,依据飞行试验大纲开展了地面系统仿真试验和空中飞行试验。飞行试验结果表明,所有科目均一次性达标,空中试飞和地面试验结果一致性良好,仿真试验系统完整有效。
A universal m-171 helicopter AΠ-34Б autopilot simulation and digital semi-physical simulation test system was built. The aeronautical and electronic signal simulator with analog and digital combined interface was developed and a Mi-171 helicopter Linear mathematical models of flight dynamics, a ground-based semi-physical simulation test environment for analog and digital flight control systems was set up, and ground system simulation tests and air flight tests were carried out according to the flight test program. Flight test results show that all subjects are one-time compliance, flight test and ground test results of good agreement, the simulation test system is complete and effective.
