Descripción del proyecto
THE PROJECT PROPOSES THE CONTINUED DEVELOPMENT OF THE STRATEGIC LINES OF THE GROUP IN ELECTRIC SPACE PROPULSION, EIGHT OBJECTIVES ARE DEFINED THAT COVER A BROAD SPECTRUM OF ACTIVITIES, FROM ADVANCED STUDIES AND IMPROVEMENT OF MATURE PLASMA PROPULSION SYSTEMS, TO THE ANALYSIS AND DEVELOPMENT OF DISRUPTIVE TECHNOLOGIES, THE PROJECT RELIES ON A MULTIDISCIPLINARY METHODOLOGY BASED ON THE NUMERICAL TOOLS AND EXPERIMENTAL CAPABILITIES OF THE GROUP (TO BE AMPLY EXTENDED),FIRST, ANOMALOUS TRANSPORT IN HALL THRUSTERS WILL BE MODELED, A CENTRAL PROBLEM SCARCELY UNDERSTOOD AND LEADING TO SIGNIFICANT EFFICIENCY LOSSES, A COMBINATION OF FLUID AND KINETIC STABILITY ANALYSES WILL BE USED, THE STUDY SHOULD CONCLUDE WITH SIMPLE TRANSPORT LAWS THAT ALLOW ITS IMPLEMENTATION IN THRUSTER DESIGN CODES,SECOND, THE PHYSICS AND NUMERICAL ALGORITHMS OF THE MODULAR 2D HYPHEN SIMULATION CODE FOR HALL THRUSTERS WILL BE IMPROVED, IN PARTICULAR, ALGORITHMS RELATED TO THE MAGNETIC MESH, THE PLASMA-WALL INTERACTION, THE HOLLOW CATHODE MODEL, AND ALTERNATIVEPROPELLANTS WILL BE IMPROVED, THE EXTENDED AND PARALLELIZED CODE WILL ALLOW THE GEOMETRIC AND MAGNETIC OPTIMIZATION OF THE THRUSTER,THIRD, THE PHYSICS AND NUMERICAL SCHEMES OF THE 3D EP2PLUS SIMULATION CODE FOR PLASMA THRUSTER PLUMES WILL BE ENRICHED, IN PARTICULAR, NEW FLUID CLOSURES FOR ELECTRONS WILL BE IMPLEMENTED, BOUNDARY CONDITIONS WILL BE IMPROVED, AND MORE ROBUST ALGORITHMS FOR MAGNETIZED PLUMES WILL BE DEVELOPED, THIS WILL ALLOW TO STUDY THE EFFECT OF THE VACUUM CHAMBER IN LABORATORY EXPERIMENTS, FINALLY, A PRELIMINARY FULL-PIC 2D STUDY WILL BE CARRIED OUT TO INVESTIGATE THE ELECTRON KINETICS IN THE PLUME,FOURTH, THE PHYSICS AND IMPLEMENTATION OF THE HYPHEN CODE ELECTRON-WAVE AND PLASMA INTERACTION MODULES, AIMED AT THE STUDY OF PLASMA THRUSTERS WITHOUT ELECTRODES, WILL BE IMPROVED, AFTER THE NUMERICAL ANALYSIS OF THE SPURIOUS SOLUTIONS IN THE WAVE MODULE, THE ELECTRON AND WAVE MODULES, THEIR COUPLING, AND THE MESH INTERPOLATION ROUTINES WILL BE IMPROVED TO PERFORM COMPLETE SELF-CONSISTENT SIMULATIONS, THE KINETIC MODELING OF THE MAGNETIC NOZZLE WILL ALSO BE ADDRESSED,FIFTH, THE EXPERIMENTAL CAPABILITIES OF THE GROUP WILL BE ENHANCED WITH THE DEVELOPMENT OF NEW PLASMA DIAGNOSTIC SYSTEMS: PROBES FOR THE ANALYSIS OF ANISOTROPIC EFFECTS, AND NON-INTRUSIVE OPTICAL SYSTEMS SUCH AS SPECTROMETRY AND INFRARED THERMOGRAPHY, THE THRUST BALANCE AND VACUUM CHAMBER EQUIPMENT WILL BE IMPROVED, ADDRESSING THE EXPERIMENTAL STUDY OF CHAMBER EFFECTS, FINALLY, DATA-DRIVEN DATA ANALYSIS TECHNIQUES WILL BE DEVELOPED TO IDENTIFY ADVANCED PATTERNS AND CORRELATIONS BETWEEN MODES IN EXPERIMENTAL DATA,SIXTH, A HALL THRUSTER PROTOTYPE WILL BE EXPERIMENTALLY INVESTIGATED, CHARACTERIZING ITS PERFORMANCE IN DETAIL AND EVALUATING THE EFFECT ON THEM OF CONFIGURATION CHANGES, THE EXPERIMENTAL RESULTS WILL BE COMPARED AND SERVE TO VALIDATE THE HYPHEN CODE, FINALLY, IT WILL CONCLUDE WITH THE CONSTRUCTION OF AN OPTIMIZED THRUSTER DESIGN,SEVENTH, AFTER THE CONCLUSION OF OTHER ONGOING PROJECTS THAT INVOLVE THE DEVELOPMENT OF TWO ELECTRODELESS THRUSTERS (HELICON PLASMA THRUSTER AND ECR THRUSTER), THEIR PERFORMANCES WILL BE EXPERIMENTALLY CHARACTERIZED, ALTERNATIVE CONFIGURATIONS IN TERMS OF GEOMETRY AND MAGNETIC FIELD, AND THEIR POSSIBLE ADVANTAGES, WILL BE DEFINED AND STUDIED,A FINAL OBJECTIVE IS OPEN TO PROSPECTIVE STUDIES OF OTHER TECHNOLOGIES, PROPULSION ESPACIAL ELECTRICA\PROPULSION POR PLASMA\SIMULACION NUMERICA\TECNICAS EXPERIMENTALES CON PLASMAS\INGENIERIA AEROESPACIAL\DISEÑO DE PROPULSORES
