Research Progress on Monitoring of Solid Rocket Motor Propellant Grain Status

固体火箭发动机的健康状况在很大程度上取决于装药的实时状态,因此对装药状态进行监测是确保固体发动机结构完整性和使用可靠性的重要基础。本文从环境状态监测、化学状态监测、力学状态监测以及监测数据综合应用4个方面综述了相关的研究进展,指出了装药状态监测的必要性,多方面总结了装药状态监测取得的研究成果与存在的不足,并针对监测技术手段及监测数据应用等方面提出了发展构想。分析认为,监测技术应聚焦在嵌入式传感器相容性技术、新理念传感技术以及长寿命技术等方面,监测数据应用方面应大力建设数据库、诊断和预测健康管理系统,以期借助有限元模型更新方法推动固体火箭发动机全寿命数字孪生技术的发展。

The health condition of solid rocket motors largely depends on the real⁃time status of the propellant.Therefore,moni⁃toring the propellant status is an important foundation for ensuring the structural integrity and reliability of solid rocket motors.We provides a comprehensive review of research progress in the monitoring of propellant status from four aspects:environmen⁃tal status monitoring,chemical status monitoring,mechanical status monitoring,and integrated application of monitoring data.The necessity of propellant status monitoring is highlighted,and the research achievements and shortcomings in propellant status monitoring are summarized from multiple perspectives.Furthermore,development ideas are proposed for monitoring technology and the application of monitoring data.The analysis suggests that real⁃time monitoring technology should focus on embedded sensor compatibility,new sensing technology,and long⁃life technology.In terms of the application of monitoring data,efforts should be made to establish databases,diagnostic and predictive health management systems,in order to promote the develop⁃ment of digital twin technology for the full life of solid rocket motors using finite element model updating methods.
