AbstractThree rocket propulsion systems are reviewed with a view to help designers in their projects, emphasizing the points they have in common and also their differences. (i) Hydrazine decomposition engines: ignition and extinction are examined, as well as thrust modulation by injection rate variations. The unstable functioning domains are defined. (ii) Two-liquid rockets: transient regimes are analyzed, and the new method proposed, based on the finite volume concept, allows the prediction of the various transient regimes as long as the fluctuation period exceeds one millisecond. (iii) Solid propellant rockets: analysis of ignition and extinction with a view to predict pressure evolutions.
