Modeling and Simulation of a Satellite Propulsive Subsystem by Physical and Signal Flows 2013-36-0105

Modeling and Simulation (M&S) of dynamic systems based on computers is a multidisciplinary field that involves several knowledge areas and tools, and is broadly used in all development areas of space industry such as rocket and satellite design and construction.
Once space systems are divided into several subsystems for ease of engineering, their models are divided the same way for the same reason. Such models may be done using different computational tools that are based on either physical flows, informational flows, or hybrid flows, depending on the subsystem nature. This is specially true for a satellite propulsion subsystem, and its physical (volume, mass, energy, enthalpy, entropy, linear momentum, etc.) flows.
This paper presents the modeling and simulation of a satellite propulsion subsystem by physical and signal flows. To accomplish this task, two different computational tools were used: AMESim and MatLab.
The first part gives a general view of M&S, showing its importance in modern engineering. After that, there is a brief description of the space subsystem (MultiMission Platform - MMP - propulsive subsystem), with its main components and tubing. The third part presents briefly the mathematical and simulation models. Conclusions shows some simulation results.
