高精度发动机转速信号的测量与模拟技术研究

High-precision Engine Speed Signal Measurement and Simulation Technology

飞机发动机工作性能如何主要反映于发动机高、低压转子转速、燃油流量和排气温度、滑油压力等技术参数。介绍了如何实现高分辨率、高精度的发动机转速N1、N2信号测量、模拟技术工作原理以及主要性能指标、硬件设计、软件方案等。

The performance of aircraft engine largely depends on the parameter such as the engine rotor speed in the condition of high and low pressure, fuel flow, exhaust temperature, oil pressure and other technical parameters. This article discusses the implementation of the high-resolution, high-precision measurement of engine speed N1, N2 signals. Furthermore, we describe the analog teehnology works and the main performance, hardware and software design.
