Análise do conjunto motopropulsor elétrico e sua influência no desempenho de VANT's

Abstract

This paper aims to evaluate the consumption and performance characteristics of the electric powertrain of a UAV (Unmanned Aerial Vehicles), in addition to proposing a method to calculate the autonomy and the range of this UAV. For example, for the successful mission of an aerial reconnaissance UAV, it is highly desirable to predict and know the flight performance conditions. For this, measurements were made on a test bench considering different levels of supply voltage and different Throttle levels of the powertrain, simulating the battery discharge cycle and the operational condition of the flight. Later, these data were crossed with a theoretical discharge curve of the LiPo battery, which represents the useful its life, for a given discharge current. The results show the expected range and the range of the UAV for a certain cruising speed. Since, optimum operating conditions are verified as a function of the performance of the powertrain under different flight conditions.
