Autonomous fault diagnosis and pre-launch control for cryogenic rocket

摘要:

低温火箭的加注和发射控制流程比较复杂，测发技术方案对火箭的测发效率、发射成本以及任务的可靠性和安全性有着重要影响，面对日益增加的航天发射任务，先进的测试发射技术已成为提升火箭竞争力的重要发展方向。针对正在研制的面向商业发射市场的新型低温运载火箭，为提高火箭测试发射效率和本质安全性，对自主故障诊断和发射控制技术开展了系统性研究，采用功能和层次抽象模型，建立了一体化地面测控设备的软硬件层次关系和“一键”式发射控制软件的架构设计方案；提出低温动力系统自动发射流程的层次设计模型以及故障诊断策略和诊断方法，为低温火箭一体化自主测发控系统的工程研制奠定了技术基础。

Abstract:

The pre-launch operation and control process of cryogenic rocket is very complex. The test and launch technology scheme has an important impact on the launch efficiency, cost and mission reliability and safety. Also, advanced test and launch technology has become an important development direction to enhance the rocket's competitiveness. A systematic study on autonomous fault diagnosis and launch control technology is carried out for a new type of cryogenic rocket being developed for commercial market. The hierarchical relationship for hardware and software of integrated ground equipment is established by using functional and hierarchical models. Architecture of "One Key" launch control software，hierarchical design model of automatic launching process for cryogenic propulsion system, fault diagnosis strategy are presented，which provide a technical foundation for the development of the integrated autonomous launch and control system of cryogenic rocket.
