摘要/Abstract

摘要： 对二台发动机三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。

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.
