| 为了更准确评估陶瓷基复合材料全环火焰筒的热疲劳性能，考核陶瓷基构件与金属件之间的连接件设计能否满足使用
要求，开展了燃油流量循环控制时序的火焰筒热疲劳试验。根据试验特点和要求，制定了试验所需的燃油流量控制方案、试验过
程风险控制方法、数据录取方式及处理方法等。在陶瓷基复合材料全环火焰筒上开展了2个燃油流量循环控制时序、200次循环
的热疲劳试验。结果表明：燃油流量控制方案、试验过程风险控制方法、数据录取方式及处理方法等能够满足火焰筒热疲劳试验
的要求；在试验工况下，火焰筒壁温最高为1010 ℃；经过400 min的热疲劳试验，火焰筒及连接件未损坏，证明陶瓷基复合材料全
环火焰筒在试验工况下的可靠性高。 |

| In order to more accurately evaluate the thermal fatigue performance of the ceramic matrix composite full-annular flame
tube and assess whether the design of the connection between the ceramic matrix component and the metal component can meet the
operational requirements， the flame tube thermal fatigue test with fuel flow cycle control sequence was conducted. According to the
characteristics and requirements of the test， the fuel flow control scheme， test process risk control methods， data recording and processing
methods were developed. The thermal fatigue test of the ceramic matrix composite full-annular flame tube with two fuel flow cycle control
sequences and 200 cycles was conducted. The results show that the fuel flow control scheme， test process risk control methods， data
recording and processing methods can meet the requirements of the flame tube thermal fatigue test. Under the test condition， the maximum
flame wall temperature is up to 1010℃. After the 400-minute thermal fatigue test， the flame tube and the connecting components were not
damaged， proving that the ceramic matrix composite full-annular flame tube has high reliability under the test conditions. |
