Item Análisis de la resistencia mecánica de la punta de ala WING TIP-FAIRING ASSY luego de ser reparada con materiales alternativos(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-09) Montero Tobanda, Jonathan Wladimir; Arroba Arroba, Cesar HernánThis investigation began with an evaluation of damage by visual inspection of all Wing Tip Fairing Assy components. It was necessary to consider the analysis of the codes for the inspection and reparation of aircrafts. For this, visual inspection reports were issued detailing each of the indications detected on the aerodynamic surfaces. Besides, the materials used in the reparation process follow the laminate configuration of the original components; copper, carbon fiber, kevlar, and fiberglass mesh, as well as a matrix of epoxy resin from the AEROPOXY brand. Furthermore, for the foundation of the restoration process, we based on the recommendation given by the manufacturer’s maintenance manuals, specifically in the parameters of step roughing, and conformed to the vacuum of the repair patches. The study of mechanical resistance of the repaired components was achieved with the application of the reflection essay in three points according to the NTE INEN 2047 standard. In addition, it helped to establish the tensile strength values, elasticity modulus, and the percentage elongation of composite materials. The results obtained were evaluated and analyzed based on FAA airworthiness parameters and previous research, these being the references that validate the repair procedure on Wing Tip Fairing Assy composed of alternative materials. Then, the repair process defined by staggered patches in an oval and vacuum shaped configuration is an effective method in the restoration of flight surfaces.Item Construcción del componente Wing Tip - Fairing Assy aplicando técnicas de ingeniería inversa y utilizando materiales alternativos para la flota de aeronaves de las Fuerzas Armadas(Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2021-04) Palacios Palacios, Hugo Wilfrido; Arroba Arroba, César HernánFor the process reverse engineering of the component began with a fiberglass replica which serves as a matrix for the initial pattern. It is taking as a model and making dimensional corrections concerning the original model. However, a replica model was obtained which was used to manufacture the final mold. On the other hand, to create a CAD model of the original part, a 3D scan and digitization were applied to later perform a treatment to the point cloud and obtain a surface of the model. The materials proposed for the construction of the component are; fiberglass, Kevlar fiber, carbon fiber, and copper mesh, with an Aeropoxy resin matrix. The process used to manufacture the component was using a vacuum bag, since it allows to achieve good lamination properties. With the Ansys Research software, component tests were carried out simulating a cruise flight with the proposed material. With which it was possible to establish deformation and stress values and through a failure criterion for composite materials to determine the inverse reverse factor and a safety factor. It can help you evaluate if the material fails or not. The results obtained from the simulation determined that the greatest stresses are concentrated in the area of the component holes, especially in the soffit and on the leading edge. The material proposed for the construction of the component reaches the established requirements.Item Análisis aerodinámico de un prototipo de auto eléctrico BIPLAZA UTA CIM17(Universidad Técnica de Ambato.
