| 摘 要： | 对二台发动机二次地面静止试验结果进行了诊断,确认存在纵向中频声不稳定燃烧。简要地回顾了固体火箭发动机不稳定燃烧问题的历史,同时从机理出发指出不稳定燃烧具有“多发性”、“随机性”的原因。从而,结合其产生的危害性的提出了对其研究的必要性。提出了研究这一问题的最基本的工程方法。 |
| 关 键 词： | 固体推进剂 火箭发动机 燃烧稳定性 |

| Abstract: | The combustion instabilities of two solid rocket motors three firingtests are diagnosed. All of the tests exhibit mid-frequency longitudinal mode instability. The history of study on combustion instability problem of SRM is briefly reviewed. It is pointed out that the reasons for " multiple" and " randomll characteristies of the instability and the necessity of study on the instability' An engineeringmethod of study on instability is also proposed. |
| Keywords: | Solid propellant rocket engine Combustion stability Vibrationalcombustion Engineering evaluation test |
