摘要
研制成一种新型的用于固体火箭发动机羽焰温度分布测量的棱镜分光式多点多波长高温计,高温计能够同时测量目标平面上均匀分布的6个点8个谱段的热辐射,目标平面点的空间位置由光阑透镜上的通光孔精确确定.该仪器具有高速的响应能力,配以特别设计的同步数据采集系统,可以保证在测量对象剧烈变化时,不同谱段热辐射对应同一时刻真温.
A new type of multi point multi wavelength pyrometer for solid propellant rocket engine flame distribution measurement was developed successfully. The instrument can record the radiation fluxes of 8 wavelengths for uniformly distributed 6 points on the target surface, which are well defined by the holes on the field stop lens. The fast response pyrometer with the specially designed synchronous data acquisition system can assure that the recorded thermal radiation fluxes of different spectrum region are of the same time and the same true temperature even with dramatically changed targets.
