新型飞行器利用动态瞬时角速率信号进行气动辨识。遥测系统采用光纤陀螺测量动态瞬时角速率信号,通过RS422串口与采编设备进行数字通信,通过同步信号和移位脉冲信号控制角速率信号同步采集与传输,且在传输信号中设置帧头和帧尾,保证了数据信号同步的正确性。测试结果表明光纤陀螺动态测量精度达到0.01°/s,随机振动过程中的均值漂移优于0.01°/s,且具有良好的抗力学环境能力。
The new aircraft uses dynamic instantaneous angular rate signals for aerodynamic recognition. Telemetry system uses fiber optic gyroscope to measure dynamic instantaneous angular velocity signal, and carries on the digital communication through the RS422 serial port and the editing equipment, through the synchronization signal and the shift pulse signal controls the angular velocity signal synchronization acquisition and the transmission, and in the transmission signal establishes the frame head and the frame tail , To ensure the correctness of the data signal synchronization. The test results show that the dynamic measurement accuracy of fiber optic gyroscope reaches 0.01 ° / s, mean drift in random vibration is better than 0.01 ° / s, and has good resistance to environmental and environmental factors.
