Workflow-based process management in virtual test of liquid rocket engine

The digitalized test process management in the virtual test of liquid rocket engines is studied. By analyzing the virtual test process of such engines, the workflow-based process simulation model of test management system is established, and a hierarchical architecture is proposed to support the test process management system. The architecture provides a unified test information integrated platform and an application service environment for the entire virtual test process. Taking preparatory stage of the test as an example, the integrated application of the the management system is shown, and the implementation process based on graphics management system is introduced. A conclusion of optimized consumption of resources is achieved. The test process management system presented in this paper for the virtual test of liquid rocket engines can provide a theoretic foundation for resource utilization in real test. It conduces to farther research in digitalized test process management in the field of space technology.
