摘要:280-6G型球形指示器电子部件的国产化是利用模拟、数字集成电路对功率放大器模板和故障探测器模板进行研制。功率放大器模板选用LM1875。故障探测模板采用LM4801、LM14001和LM124以实现。研制的电子部件能提高指示器的跟踪速度,降低系统的动、静态电流。同时,还能完成球形指示器与原机陀螺平台和仿形装置的配套工作,精确指示飞机的姿态角和航向角。
The electronic unit of 280-6G global indicator is developed using analog-digital IC technology that developing the templates of the integrated power amplifier and failure detector. LM1875 is used to complete function of the template for the integrated power amplifier. LM4801, LM14001andLM124 are used to complete function of template for the failure detector. The developed electronic units can improve the tracking velocity of the indicator, reduce the dynamic and static current of system, at the same time, complete the matching task of the global indicator and former gyro platform and profiling set, and indicate the aircraft抯 attitude and course accurately.
