Summary:	Aircraft engines operate by Newton's Third Law, which states that for every action, there is a reaction. Normally, those that operate at low Mach produce thrust by a combination of engine and propeller. The propeller works by pushing air backward, it may propel a high quantity of air at a lower speed until a small quantity at higher velocities. In this thesis, an analytical method to optimize the design and performance of a propeller is presented. The main objective is to create an approach, that defines an optimal airscrew that will best suit an engine. Accurate propeller predictions are crucial in aircraft performance since detailed analysis consists of computational simulations or experiments, which are highly time-consuming and expensive. First, the Blade Element Momentum Theory is implemented, based on a database built by XFOIL. To validate, the results are compared with other analytical and experimental results from other theses. Then, an algorithm of optimization called Accelerated Differential Evolution was implemented. It developed an optimized propeller that produces 4\% higher efficiency compared to the one made for an electrical aircraft.
