| 摘 要： | 讨论了气流方向对一种机载总温传感器动态特性的影响，发现气流偏角对传感器的动态特性有很大的影响，首次提出了总温传感器动态特性的方向敏感性概念。本文分析了其原因，并指出在设计、生产和使用过程中控制气流偏角的大小，否则将破坏传感器的动态性能。这一结论也适用于与结构类型相似的其它总温传感器。

| Abstract: | The effect of the gas flow direction on the dynamic characteristic of a kind of the airborne total temperature sensor is discussed.Discovering that the deviation angle of the gas flow has an great effect on the dynmic characteristic of the sensor,the concept of directional sensitivity of the total temperature sensor is advanced for the first time.The reason of that is analyzed in this paper.And it is pointed out that,during the procasses of design,manufactrue and using,controlling the directional diviation is necessary,if not,the dynamic characteristic of the sensor will be aggravated.This conclusion can be adapted to other total temperature sensors with similar constructure. |
