| 摘要: |
| 对液体火箭尾部喷焰红外辐射特性进行了仿真计算。利用所扩展建立的液体火箭发动机尾喷焰红外辐射组分的谱带参数数据库和尾喷焰流场数值仿真结果对辐射传输方程进行了数值求解，得到不同观测条件下的光谱辐射亮度。通过与实测数据对比，表明计算方法可行，结果合理。 |

| Abstract: |
| The IR radiation characteristic of exhaust plume of the liquid rocket is numerically calculated. Based on the established HITRAN database and the numerical simulation results of the exhaust plume field, the radiation transmission equation is numerically solved. The absorption and radiation of the atmosphere are considered. The calculation results indicate that the transmission conditions, height and angle, exert important influence on the distribution of spectrum intensity. The spectral irradiances achieved by solving the RTE are compared with the test data, which show that the calculation method is feasible and the solution is proper. |
