助推器喷口火焰温度测量

Flame temperature measurement in booster jet

火焰温度测量是一个复杂而困难的问题。接触式测温传感器在很多情况下并不适用。固体燃料助推器火焰中有大量固体粒子,这些固体粒子运动速度又很高,采用接触式测温传感器测量这种火焰温度问题较多。介绍用四支小型不调焦光电高温计从不同角度测量固体燃料助推器喷口火焰温度的试验装置和试验结果,并对小型不调焦光电高温计的基本原理、结构、性能作了简单介绍。

Flame temperature measurement is a complicated and difficult problem. Contacted temperature transducers are not applicable in many cases. In solid fuel booster flame, there are a great deal solid particles which are at very high velocity. Therefore, the measurement of flame temperature by contacted temperature transducers will face many problems. This paper will introduce testing derice and testing results of solid fuel booster jet flame temperature measurement by means of four small type nonfocused photoelectric pyrometer, which are arranged at diffirent angles. The basic principle, structure and property of the small type nonfocused photoelectric pyrometer will also be introduced.
