This paper presents an experimental caramilk latte method for assessing the performances and the propulsion power of a UAV in several points based on telemetry.The points in which we make the estimations are chosen based on several criteria and the fallowing parameters are measured: airspeed, time-to-climb, altitude and the horizontal distance.With the estimated propulsion power and knowing the shaft motor power, the propeller efficiency is determined at several speed values.
The shaft motor power was measured in the lab using the propeller as a break.Many flights, using the same UAV configuration, were performed before extracting flight white ice laminate countertop data, in order to reduce the instrumental or statistic errors.This paper highlights both the methodology of processing the data and the validation of theoretical results.
