- ÍtemAnálisis de desempeño del motor PT6A-20 de la Fundación Universitaria los Libertadores para la optimización de su funcionamiento.(2024-01-16) Villanueva Caviedes, Jhon Nicolás; Bermúdez Muñoz, William David; González Cruz, Francisco Javier; Rubio Ospina Juan Pablo, CodirectorEl motor PT6A-20 de la Facultad de Ingeniería y Ciencias Básicas (FICB) de la Fundación Universitaria Los Libertadores (FULL), ha tenido durante los últimos diez años un uso exclusivamente pedagógico, al ser utilizado por cortos intervalos de tiempo y en condiciones en las que normalmente no operaría. Teniendo en cuenta lo anterior, la FULL no cuenta con ningún tipo de programa de mantenimiento especializado para el motor según estos intervalos de funcionamiento. Un hecho trascendental es que en más de una década solamente se le ha realizado un proceso de mantenimiento que resultó siendo ineficaz. Considerando lo anteriormente mencionado, se busca llevar a cabo un análisis del rendimiento del motor turbohélice PT6A-20 de la FULL; dicho estudio se desarrollará en dos partes, en las cuales se efectuarán encendidos al motor para medir sus parámetros de operación mediante la información que arrojen los instrumentos de medición. Lo anterior se hará en dos momentos: en las condiciones actuales o previas al mantenimiento y en la etapa posterior al mantenimiento que se le efectuará al motor PT6A-20. Con base en dicho análisis, se quiere establecer cuál es el estado actual del equipo y compararlo con la condición a la que se llegue posterior al mantenimiento; de esta manera se puede definir qué tan eficiente es el motor bajo su margen operativo. Este análisis de desempeño busca optimizar el funcionamiento del motor, realizando una serie de recomendaciones tanto de su operación como del proceso de mantenimiento que se deberá seguir; para tal fin es indispensable recolectar datos de los instrumentos de la cabina del motor cuando este se encuentre en funcionamiento, posteriormente los datos serán analizados para generar las curvas de desempeño. Este análisis permitirá emitir un diagnóstico acertado de las condiciones actuales operativas del motor.
- ÍtemClasificación de imágenes de calles: distinguiendo entre limpias y sucias utilizando redes neuronales convolucionales mediante UAS(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Mancera Gómez, Cristian Camilo; Gutiérrez Ramírez, Sebastián Alejandro; Melo Daza, Pedro FernandoThe project focuses on image classification using artificial intelligence developed in Python. This tool aims to distinguish between two categories from a set of over 500 images. These images are captured from the air with the help of an Unmanned Aerial Vehicle (UAS). The project involves the development of Python code that employs artificial intelligence to identify and classify a large number of images into two categories: dirty streets and clean streets. The acquisition of these images is done from the air using a UAS, which follows a predetermined flight plan, has the necessary airworthiness permits, and adheres to rigorous safety and flight mapping protocols. This tool is essential for the project as it facilitates data collection and information identification using integrated data augmentation techniques in the code, allowing for image modifications as detailed in the following sections.The process of developing the code also requires proper training to ensure its correct operation and the generation of valid information without errors or distortions. For training, previously collected images from online sources were used, as well as photographs taken during a session in the Sopó area, totaling 237 images uploaded into the code. Despite the challenges involved in this entire process, a reliability percentage of over 85% was achieved. This means that the system offers considerable credibility and experiences minimal information loss.
- ÍtemRevisión de la literatura de la impacto ambiental en la atmósfera del motor de cohete emisiones durante el lanzamiento, vuelo y reentrada(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Blanco Camargo, Juan David; Mónico Muñoz, Luisa FernandaThe space technology sector is growing rapidly. This leads to an increase in the number of launches to different orbits with positive repercussions. This, however, raises concerns about the impact on the atmosphere. The pollutant emissions from rocket engines depend on the type of propellant used for launch, but regardless, the products that dominate the emissions are CO2, H2O, black carbon (BC), and alumina. The footprint of these emissions can be measured as radiative forcing or ozone loss. In this work, emissions from liquid, solid, and hybrid propellants are estimated for three different scenarios, projecting them to 5 and 10 years respectively. According to the results, BC and CO2 emissions dominate, however, with a much smaller impact than other industries. Without underestimating these emissions, measures must be taken to regulate this industry in a way that allows its growth and, in turn, cares for the environment.
- ÍtemConstrucción y análisis de ala volante reforzada con fibra de vidrio.(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Barrera Barrera, Carlos Andrés; Lozano Tafur, CristianThe main objective of this work is the design and construction of a flying wing reinforced with fiberglass adaptable for RF (Radio Frequency) and AI (Artificial Intelligence) flights at Los Libertadores University Foundation. This project has the purpose of allowing participation in model airplane events in the professional or basic category, in addition to serving as a teaching prototype for future generations acquired in innovation and learning of flying wings and drones. In recent years, the implementation of model airplanes has been observed in various universities. It has not only been used in the educational field, but it has also become an activity present in numerous competitions in which different academic institutions and schools participate. With this project, we seek to promote and further expand the field of model airplanes within our university. The final objective is that students can improve and update the circuits and materials used in the wing, in order to obtain better results and acquire practical knowledge in the design and construction of these aircraft. Likewise, it seeks to encourage participation in various contests of different categories, offering safe and stable flights that demonstrate the quality and efficiency of the developed prototype.
- ÍtemDiseño conceptual de un banco de pruebas de inyectores para motores a reacción(Fundación Universitaria Los Libertadores. Sede Bogotá., ) Montoya Garzón, Nicoll Andrea; Mónico Muñoz, Luisa FernandaAll product development must go through the conceptual design stage, which consists of in obtaining a partial solution to a problem posed from specifications, requirements and needs of a client. For this reason, in this document it was analyzed and the client was identified, to later obtain the requirements, and thus be able to have the main basis of conceptual design. This process is also characterized by using different methodologies and creative techniques, in this document various methodologies were related, which went through a step of comparison and evaluation, to choose the methodology More appropriate. After the identification of the methodology, the different creative techniques, which provided a clearer analysis and simplification of the problem, such as the use of the functional decomposition diagram, which allowed guide the client's language to design attributes, understanding the exact function of each requirement exposed by the clients; the use of various creativity techniques benefit the development of the conceptual design, because multiple concepts were created, with different design ideas, providing several solutions to the initial problem. He The next and most important step of all conceptual design is the deployment of the function of quality, which helped to relate the concepts created with the client's requirements, understanding which concept meets all design features.
