Descripció del contingut i pla d'activitats: | |
Being in the outer space and thus without gravity, buoyancy forces do not determine liquid and gas position in a vessel. In such an environment the positions are primarily driven by surface tension. Thus liquids tend to adhere to the walls and leave a gaseous bubble in the center of the vessel, which can cause serious problems for the task to provide a gas-free liquid to ensure correct operation of the engine. This is where
propellant management devices (PMDs) come into play; PMD provides a way to expel propellant in a low-gravity environment. Devices can use surface tension as the primary expulsion device with a combination of baffles, fins, and vanes. This project deals with the study and investigation of an automatic control system to improve the operation of an PMD device. Different options of combining sensor to measure the propellant pressure and servo motors as actuator to rotate the blade will be studied to ensure correct fuel aspiration. Goals to achieve with the new design are weight reduction of the PMD device to give more space for fuel as well as an increase of efficiency in its aspiration. Finally, a CAD model of the PMD device will be delivered, as well as a stability analysis of the used controller. The required software C, C++, Matlab, Python, ... is installed in the school virtual cluster (clufa), which will also be used to carry out the simulations for the project. |

Overview (resum en anglès): | |
In this thesis project, a functional PMD device was designed for the implementation of a control system and thus achieve a more efficient and controlled way of the propellant extraction process.
For this design process, an analysis was carried out on the different types of PMD devices and which ones could be used in a control system, as well as the selection of certain conditions of the meteosat second generation (MSG) satellite, to focus the design to something more attached to in practice. |
