Integrated virtual test bed for ivhm systems on 2nd generation RLV

The IVHM Virtual Test Bed (IVTB) is a systems integration and test facility being developed by Northrop Grumman Corporation and the Jet Propulsion Laboratory, along with NASA partners Glenn Research Center and Ames Research Center. Its purpose is to support the demonstration and validation of Integrated Vehicle Health Management (IVHM) technologies for NASA's 2nd Generation Reusable Launch Vehicle program. The IVTB will be used to validate spacecraft health management system designs, and to infuse, evaluate, and mature new technologies. The IVTB will be used to identi@ and resolve problems at the early stages of development and facilitate technology transfer. In addition, the IVTB can be used for assembling and testing ground and spacecraft elements using the distributed environment capabilities, and supporting post launch operations and mission scenario testing. As a proof-of-concept, a simulation of the X-34 RLV propulsion feed system and liquid oxygen tank structure was chosen. The experiment will use a hierarchical health management system wherein a system-level IVHM will collect and analyze the subsystem-level diagnostics to demonstrate capabilities not possible with only subsystem level information. 1.
