涡轴发动机进口温度测量偏大对控制系统的影响分析

Analysis of Influence of Higher Import Temperature Measurement of Turboshaft Engine on Control System

针对涡轴发动机多次出现的发动机进口温度T1与环境温度T0之间存在差异而导致控制系统性能偏移的现象。在阐述影响T1测量偏大主要因素的基础上，着重分析T1测量偏大对发动机起动、加减速、导叶控制、起动放气及Ngcr限制方面的影响。

There is a difference between the turboshaft engine inlet temperature T1 and the ambient tempera- ture 70, which leads to a deviation in control performance. Based on analysis of the main factors affecting the accuracy of T1 measurement, the effect of higher T1 measurements on the control of engine start, acceleration, deceleration, guide vane control, starting bleed and Ngcr limitation is emphatically analyzed.
