Experimental Methods for UAV Aerodynamic and Propulsion Performance Assessment

Blog Article

This paper presents an experimental 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 ls32a804nmnxgo shaft motor power, the propeller efficiency is determined at several speed values.

The 006719f 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 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.
