“…A very common issue was also the missing method for storage of measured values, where the measured data was written down only by an operator that controlled the measurement cycle [1][2][3] or it was sent by Bluetooth or USB to the computer for further analysis [4,5,7]. Our proposed solution is based on an automatic measurement cycle, where 10 measurements of each quantity are performed to obtain the best possible data.…”

“…Other novel approach in comparison to the cited papers [1][2][3][4][5][6][7][8][9] is the fact that we have designed a measurement system that is compatible with most of the used BLDC motors on medium and large sized UAVs.…”

“…When we compare the results of the regression analysis with the interpretation described by Szafranski [8] and Ryll [9] we found out, that their dependencies on different propellers were similarly approximated by cubic functions like it was in our case. Other authors in [1][2][3][4][5][6][7] had very similar dependencies, but unfortunately, they did not publish a regression model that would describe the acquired data.…”

Experimental Measurement of a UAV Propeller's Thrust

et al. 2022

At present, there are several types of propellers in the field of the use of Unmanned Aerial Vehicles (UAVs) with unknown parameters, where it is necessary to provide information about their thrust, current consumption and maximal rotational speed (RPM). Commonly used methods for measurement of a propeller's thrust are mostly based on the usage of a single purpose system, on short measurements without data storage or on inaccurate sensors. The goal of this article is to develop a universal experimental measuring system for more accurate measurement of propeller's parameters (thrust, current consumption, maximal RPM). For more accurate measurement, the battery voltage, temperature and humidity of the environment were also measured. To acquire, measure and store the data safely on a micro SD card, a processing circuit based on an ATmega2560 microcontroller was developed. This innovative approach allowed to analyse the behaviour of the propeller and to measure the dependencies of the RPM on pulse width, of the current on RPM and of the thrust on RPM at different input conditions. The measurements have shown that the dependencies can be approximated by cubic functions. The mathematical description allows predicting the behaviour of the propeller in unmeasurable conditions.
