| The research of advanced and innovative technologies is one of the main concerns within the aerospace industry. Spacecraft re-usability is one of them, being an important aspect to diminish the huge costs and resources that a space mission implicate, minimizing also the environmental impact.
This project deals with the design and computational fluid dynamics (CFD) analysis of the aerodynamic efficiency of Grid Fins as control surfaces for rocket reentry. The expected methodology is to first establish the theoretical background (subsonic and supersonic control surfaces). Then, design a prototype using SolidWorks to finally perform flow simulations and analysis using Ansys to validate its efficiency and obtain proper conclusions. A parametric of key key parameters will performed in order to control the velocity with the different forces and the pitch angle with the moments. Computational fluid dynamics (CFD) simulations will be carried out in ANSYS Fluent in order to obtain the aerodynamic parameters and evaluate efficiency. |

| Orientació a l'estudiant: | |
| The student will learn the main features regarding rocked re-entry systems, in particular grid fins. She/He has to analyze the crucial performance indicators, as geometries and operating conditions before entering the design phase. She/He has to become familiarize with the main characteristic features, e.g. fin design, applied forces, pitch, twist, aerodynamic characterstics, etc. Programming languages as Matlab, SolidWorks software, and Python will be learned and/or deepen. Simulations will be performed via AnsysFluent in order to analyse the grid fin design. Supervisor and student will meet regular basis about once
a week to evaluate the progress and discuss the following steps. In case of bigger problems the student can approach the supervisor any time in order to solve the problems as soon as possible in order to avoid any hold backs. |
|
| Horari d'atenció a estudiants per a l'assignació de projecte: Regular meetings of about 1-2h will be setup weekly in order to check, discuss and evaluate the progress as well to plan the following steps. In case of bigger problems extraordinary meetings will be done as soon as possible. |
