The aeronautic and aerospace sector are in constant development, in which more and more progress is being made. This sectors¿ growth can be considered exponential, as it is bound to the new technologies, which in the last decades have undergone an extraordinary expansion. The future of a sector is defined by all times by the means that it is influenced; in this case the air or the space. Therefore, it is indispensable to adapt to it and be able to resolve all the problems that can occur during the effectiveness of the aircraft. In order to avoid personnel and/or material damage, experimental and theoretical investigations are conducted with the objective of understanding the attributes and the behavior of the air, that is to say, studies are carried out about the fluid mechanics around the object. The experimental tests are conducted in wind tunnels, but it has been confirmed that they can be done likewise in a water tunnel. Even the use of this presents various additional advantages to the wind tunnel, because the results can be understood in a more visual manner, as well as having a superior range of measurements as water has major density and viscosity than air. In this project, a series of investigations about the most important facets to take into account when implementing a system of measurement and visualization in the test section of a water tunnel has been developed. For that the properties of the water and the respective treatment that must be conducted have been analyzed. The properties of the water tunnel and the facets to take into account for the implementation of an ensemble of sensors, with the objective of understanding in an experimental manner the behavior of the water in a determined test section have been analyzed as well. In addition, a structure has been designed that will allow to position the sensors in any spot of the section that wishes to be analyzed. In this way, the behavior of the fluid can be comprehended and afterwards it would allow to carry out experiments that simulate a real situation by means of an equivalence of mathematical equations. Consequently, it will be possible to study some critical situations on objects that simulate parts of an aircraft without endangering the personnel. |
