Abstract
Los últimos avances en la tecnología de manufactura, han permitido la integración de sistemas que incentivan el desarrollo expedito y de bajo costo del prototipado de piezas conceptuales y funcionales para su utilización en los procesos de diseño. Junto con esto, las últimas tecnologías en el desarrollo de aeronaves, han permitido el acceso de esta al mundo civil e industrial, entregando una amplia variedad de utilizaciones con el fin de capturar información del entorno, como también de transportar cargamento y/o ser utilizado como herramienta para alguna tarea en específico.Además, la unión de los procesos de diseño y las tecnologías de información permiten el acceso a prototipos para personas que, sin necesariamente tener conocimientos en el desarrollo de modelos 3D en software, puedan realizar la manufactura de piezas funcionales con la posibilidad de modificarlas y adecuarlas a sus propios requerimientos.En el presente trabajo, se utiliza una metodología de etapas para el desarrollo de un modelo de estructura paramétrica de un Drone dependiente de los equipos que el usuario final desee instalar, utilizando las dimensiones de estos como parámetros que, al ser ingresados en una interfaz gráfica, generan un diseño CAD parametrizado, entregando al usuario la posibilidad de adecuarse a distintos tamaños dependiendo de los requerimientos iniciales. El archivo CAD generado posteriormente, se fabrica con la utilización de tecnología de manufactura aditiva para su posterior anclaje de piezas, entregando la posibilidad de realizar pruebas de vuelo.En su desarrollo, se muestra un caso de estudio para la parametrización de dos sistemas generales, en donde las variables de diseño dependen de las características específicas de cada subsistema de estudio. Se desarrolla una metodología para la selección del equipamiento a utilizar, en cual se selecciona entregando los parámetros a usar en el futuro diseño.Finalmente, se propone una opción de aplicación que muestra, en uno de los casos, la necesidad de experimentación para la comprobación de variables y realización de pruebas de vuelo.
The last advances in the manufacturing technology has allowed the integration of the systems that encourage a both fast development and low cost on the prototype of conceptual and functional pieces for use them in the design process. Furthermore, the last technology of UAV development has allowed the access of this on the civil and industrial world, giving a wide variety of uses with the purpose of capture the environment information, as well payload transport and/or be used like a tool for some specific tasks.Further, the union of both design process and information technology allows access to prototype for people that, without knowledge in software development 3D models, can perform functional pieces for manufacturing with the possibility to adjust and adapt to their requirements.In this work, we use a methodology of steps for the model’s development of a parametric structure of a Drone (a method is disclosed, which comprises the development of a parametric model for a Drone´s structure) depending of the equipment that the final customer wish to install, using the dimensions of this like parameters that can entering into graphical interface and after will generate a CAD parametric design, give to the customer the possibility to adapt to different dimensions depending of the first requirements. The generation of CAD (.STL file), it’s made with the technology of additive manufacturing, doing the pieces anchorage and giving the possibility of performing flying test.During the development, it shows a case of study the parameterization of two general systems, with the design variables depending of specific characteristic of each subsystem in study. In addition, it’s developed a methodology for the selection of equipment to use that to be selected give the parameters to use in the future design.Finally, is proposed an option of application that show, in one case, the needs of experimentation with both the testing of variables and perform of flying test.
