THE APPLICATION OF BOND GRAPHS IN THE MODE- LING OF LIQUID ROCKET ENGINE SYSTEMS |

Abstract: |
Bond graphs have been shown to be useful in modeling of a wide variety of physical dynamic systems.A unique feature of bond-graph techniques is that they provide the modeler with a graphical representation of the causality (i.e.the input-output relationships)in the underlying system.In this paper,bond graphs of variable-thrust rocket engine system are developed and governing state space equations are derived. |
