Abstract
Integrated in the LEEUAV project, the objective of this work was to optimize the propeller-driven propulsion system previously implemented. A propeller was parametrized in terms of planform and airfoil shape and the software QPROP used to evaluate the performance of in terms of thrust, power and thrust coefficient and propeller efficiency. Experimental tests were conducted for three different propellers to study study the performance sensitivity to propeller diameter and pitch, electric motors, and also to validate the numerical model. Following those tests, a multi-objective shape optimization using MATLAB\(^{\textregistered }\), for cruise and climb conditions, was performed. At the end of this optimization, a system motor\(+\)propeller with an higher efficiency was obtained.
