| Abstract: |
| For monitoring conditions of a liquid rocket engine with turbo-pump system, an outline of fault detection and diagnosis is presented in this paper. The fault detection method with extended Kalman filter based on nonlinear mathematical models and the diagnosis method based on lower-order linear models are also discussed. |
