The world is going through a constant evolution, where the objectives are much more ambitious than before thanks to the new technologies. However, the focus is no longer on only improving existing services without considering anything else; nowadays, the benefit provided is just as important as the way in which it is achieved, and the main efforts currently are focused on achieving a sustainable world, in which life continues to be as we know it and climatic catastrophes are eradicated, at least those in which human activity is the main cause. That is why this thesis is focused on the implementation in the aeronautical industry of a promising technology called Active Flow Control (AFC). To that end, an exhaustive state-of-the-art is conducted in which the AFC technology is described in general, to then deep dive in its aeronautical applications. Next, the technology required so as to implement the AFC in an aircraft is described, covering the main elements needed to influence the flow around the aircraft together with the power supply architectures necessary to feed the actuators. On the other hand, and based on the information previously gathered, a Minimum Viable Product (MVP) is defined, in which AFC technology is to be implemented in an Airbus A-320 aircraft. In the MVP, both the technological elements that need to be installed together with the system infrastructure are established, thus defining the architecture of the product. In order to ensure the viability and profitability of the MVP, a feasibility study is conducted, analysing the installation of the product from an airline perspective considering three different casuistic: an aircraft that flies only at national level in Spain, an aircraft that flies at international level in Europe and a complete fleet of Airbus A-320 that flies at international level in Europe. The preliminary economic analysis covers the three cases mentioned, and the complete economic figures are presented for the third case, the one with more practical interest. On the other hand, the regulatory emissions framework currently in place in Europe is described, assessing whether the installation of the MVP in a European airline could influence the overall company strategy towards the 2050 zero net goal achievement. Due to the current situation, in which the global awareness of contaminant gases emissions has increased considerably, all the projects aiming to reduce this type of emissions have a great impact in the industry, and the AFC technology investigations are a good opportunity to improve aeronautical industry contaminant footprint in the world.

Space is going through a new evolution, where the objectives are much more ambitious than before thanks to the new technologies. The possibilities that arise from these new achievable projects are grateful, such as creating human stations in satellites, oreven building cities for human being in other planets. In order to achieve these goals, the biggest problematic currently is the transport method, that is to say, how to reach distant celestial bodies in a viable way, focusing on both the feasibility for the human life and the economic aspects, and the first proposal is to reach Mars.To do so, a patched conic approximation will be performed so as to analyse the Earth to Mars interplanetary transfer. By using a Newton-Raphson iterative process, which includes a continuation method with a differential corrector, the Lambert problem will be solved in order to obtain the main results. It will also be done a main-materials estimation for the Mars society competition, defined as a case study of the project.On the other hand, the privatization of the space sector is adding new players to the game, and as a result of this, a new space race is taking place. The most outstanding players nowadays are NASA, on the side of government agencies, and SpaceX, from the private space sector. Both companies have presented strategies to reach the red planet, and this study is focused on the architecture analysis of the SpaceX mission, in order to analyse each of its phases, to compute the trajectory and to develop a preliminary study of the re-entry manoeuvre. Furthermore, due to the current situation, in which the interest of the manned interplanetary journeysis booming, it is important to define the suitability of the whole mission. Because of the high investment required for conducting a Mars’ colonization process, a preliminary materials budget and a first iteration of the total cost of the program will be conducted, trying to roughly quantify the amount necessary to develop the project globally.
