| 摘 要： | 以串联式TBCC加力/冲压燃烧室为研究对象,提出包含一体化整流支板、加力内锥及长短交错的径向火焰稳定器组成的TBCC加力/冲压燃烧室方案。针对TBCC发动机加力/冲压燃烧室进行了数值模拟,获得该燃烧室在不同模态下的流场特性。计算结果显示,在涡轮工作状态和涡轮/冲压共同工作状态下,TBCC发动机加力/冲压燃烧室的总压恢复系数均在95%左右;在冲压工作状态下,其总压恢复系数在86%左右。可以满足在不同模态下加力/冲压燃烧室对总压恢复系数的要求。

| Abstract: | Taking the tandem TBCC （Turbine Based Combined Cycle Engine）after-ramjet-burner as research object, the plan of TBCC after-ramjet-burner contained the integration rectifier plate, the cone and the flame holder was proposed, The flow characteristics of the TBCC after-ramjet-burner were obtained in the different model by numerical simulation. The simulation results show that the total pressure recovery coefficient is more than 95% when the afterburner work or the afterburner and ramjet-burner work together, the total pressure recovery coefficient is more than 86% when the ramjet-burner work alone. It can meet the requirement of the total pressure recovery coefficient for the TBCC after-ramjet-burner. |
