Dimensionamento do grupo moto-propulsor de um aeromodelo

Abstract

Aviation 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.
