Complements of Aerospace Engineering

Basic competences CB6 To possess and understand knowledge that provides a basis or opportunity to be original in the development and / or application of ideas, often in a research context CB7 Students must know how to apply the knowledge acquired and their ability to solve problems in new or unfamiliar environments within broader (or multidisciplinary) contexts related to their area of study CB8 Students must be able to integrate knowledge and face the complexity of making judgments based on information that, being incomplete or limited, includes reflections on social and ethical responsibilities linked to the application of their knowledge and judgments CB9 Students must know how to communicate their conclusions and the knowledge and ultimate reasons that sustain them to specialized and non-specialized audiences in a clear and unambiguous way CB10 Students must have the learning skills allowing them to continue studying in a way that will be largely self-directed or autonomous. General competences CG1 Capacity for the formulation, critical verification and defense of hypotheses, as well as the design of experimental tests for verification. CG2 Ability to make value judgments and prioritize in making conflicting decisions using systemic thinking. CG4 Ability to work in multidisciplinary teams in a cooperative way to complete work tasks CG5 Ability to handle the English, technical and colloquial language. Specific competences CE3 Ability to develop a complete system that meets the design specifications and the expectations of the interested parties. This includes the production of products; acquire, reuse or code products; integrate products in top-level assemblies; verify products against design specifications; validate the products against the expectations of the interested parties; and the transition of products to the next level of the system. CE9 Ability to understand and apply the knowledge, methods and tools of space engineering to the analysis and design of the propulsion subsystem of space vehicles.
