Item Análise de desempenho do conjunto motor-hélice para veículo aéreo não tripulado transportador de carga(2023-04-24) Abreu, Renan de Araújo; Moura, Alexandre Douglas Araújo de; Centeno González, Felipe Orlando; http://lattes.cnpq.br/9688427609049172; http://lattes.cnpq.br/3602476790054326; http://lattes.cnpq.br/1553803715502791One of the pillars, currently, in a modern civilization is aviation and the mobility, ease and convenience that this technology provides to human beings. The pioneers of aviation began with the construction of scale models, called model airplanes, which will be treated in this work. One of the most important points in the construction of a model airplane are the engine and the propeller, also called powertrain set, in this work it will be possible to see how the performance of this set was determined for the construction of an unmanned aerial vehicle carrying cargo, Within the aero design project at the university, we are going to show how the Excel and Propeler Selector software were used to acquire the data of the performance curves that the aircraft should have starting from the data coming from the aerodynamics sector that delivers the lift and drag coefficients of the aircraft, among other parameters, all calculations were carried out in order to understand the performance of the aircraft in takeoff, cruise flight and landing conditions, always taking into account the FAR-Part 23 standard. The engine had already been defined as the OS model .61FX, as well as, the propeller was also determined to be the model with a diameter of 13” and pitch of 7”, being possible to determine the performance of the vehicle to fly with a total weight of 10 kg.Item Dimensionamento do grupo moto-propulsor de um aeromodelo(2024-02-19) Batista, Leonardo Henrique Tavares; Simões, Thiago Araujo; http://lattes.cnpq.br/7903824177570749; https://lattes.cnpq.br/1898774956397470Aviation stands out as one of the essential pillars in modern society, offering individuals mobility, convenience, and comfort. In this aspect, aeromodels, representing the first step in the aviation journey, are the subject of study in this work. A crucial aspect in the construction of these aeromodels is the powerplant assembly, formed by the engine and the propeller. This study explores the process of determining the performance of this assembly for aircraft development. Using software such as Excel and Propeller Selector, data were obtained for the elaboration of aircraft performance analyses. These data, along with others provided by different aircraft areas, included coefficients of lift, drag, among other parameters. Through detailed calculations, a comprehensive analysis of the aircraft's performance was conducted in different flight phases, from takeoff to landing, always in compliance with FAR-Part 23 regulations. The motor selected for the project was the electric model D3542, while the chosen propeller had a diameter of 13 inches and a pitch of 7 inches. With these specifications defined, it was possible to evaluate the vehicle's performance to operate with a total weight of 12 kg. This analysis was essential to ensure efficient and safe flight operations, contributing to the continuous advancement of aviation and aerospace technology.
