Dynamic Models for Liquid Rocket Engines with Health Monitoring Application

Dynamic models for liquid rocket engines are developed. The particular case of the Space Shuttle Main Engine (SSME) is considered and reviewed, taking as a reference the thermodynamic model introduced by Rocketdyne, subcontractor in charge of the SSME production. Most of the possibilities involved in the design of dynamic models are shown from first principles. Rotordynamic models are also presented with emphasis in rotor-casing vibrational response. An overview of health monitoring (i.e., monitoring of the general operational condition of the engine) based on such models is introduced as well, stressing the importance of such analysis in reusable launch vehicle's (RLV's) engine development.
