NASA researchers recently demonstrated
successful real-time fault detection and isolation of a virtual reusable launch vehicle main propulsion system. Using a detailed simulation of a vehicle propulsion system to produce synthesized sensor readings, the NASA team demonstrated that advanced diagnostic algorithms, running on flight-like computers, can, in real time, successfully diagnose the presence and cause of faults.
This demonstration was conducted as part of the NASA Propulsion IVHM Technology Experiment, or PITEX.
