摘要

摘要: 针对发动机高温燃烧火焰参数非接触式在线原位测量难题,提出了基于火焰辐射光谱(radiation spectroscopy, RS)的火焰参数在线测量方法,采用光纤光谱仪搭建了发动机燃烧火焰参数在线测量系统,并利用黑体炉对光谱仪电荷耦合元件(charge-coupled device, CCD)波长响应特性进行了标定.之后,应用该系统获得了火箭基组合循环(rocket based combined cycle, RBCC)发动机地面试验高温燃烧火焰200~1100nm波段辐射光谱,结合普朗克定律与最小二乘法,实现了火焰温度与辐射率参数的在线测量,为发动机燃烧诊断与优化提供了直接数据支撑.

Abstract: For the non-intrusive, on-line and in-situ measurement of high-temperature combustion flame in engine, the method based on radiation spectroscopy (RS) was presented. The system using optical fiber spectrometer was designed for on-line parameters measurements of flame in engine. The wavelength response of charge-coupled device (CCD) was calibrated by the blackbody furnace. Then, the radiation spectroscopy range of 200-1100nm wavelength of high temperature flame in rocket based combined cycle (RBCC) engine ground testing was obtained by using this system, and the temperature and radiance of flame were determined with Planck radiation law and the least square method. It can provide important reference for combustion diagnostics and optimization of engine.
