This work consists on the development and study of a drone platform as a tool for microgravity research. By means of a study of the state of the art, it has been concluded that this drone platform has a great cavity in the current frame, approaching the investigation in microgravity thanks to its simplicity and high repetitiveness. In the past, Gravimav developed and validated a prototype that allowed microgravity conditions for small payloads for more than one second with a quality of 8*10^2 g. Using the weaknesses and strengths of this prototype as a basis, a new design has been proposed. Based on this, the drone platform has been divided into two independent drones. The first one has been defined as an ascension drone that simply has to raise weight to a certain height and the second is the one that performs the experimentation in microgravity starting from the previous mentioned height, gravidrone. The most important part of this project is the development of gravidrone aerodynamics using computational fluid dynamics. Throughout different phases it has been verified that characteristics of the geometry help to reduce the drag force that experiences, because this is the main problem that arises when trying to experiment in microgravity. Once a final design has been obtained it has been validated that the results of the simulations were correct through experimentation in a wind tunnel. In addition, a method has been introduced that allows the free movement of the experiment, even though the gravidrone is stopped by the drag force. A braking system has also been modeled to safeguard the integrity of the experiment and the gravidrone once the experimentation has been completed. Finally a mission scenario has been created and a study has been made on how the different parameters affect the operation of the platform, in this way it is possible to know the contribution of each of them in different aspects and then apply them to the design.
