“…Analyzing Equation (5) or Equation (8) and according to the thrust sign in Figure 1, it is highlighted that the air flux speed backward from the propellers is increased, with an improvement of the cooling efficiency for the mover of the propeller, as the electric motor. The speed increase can be easily determined starting from the value of thrust and using relations (5) or (8) together with the formula (9). The thrust is determined using the mechanical power of the propellers and the speed V 00 , which is assumed equal to the aircraft speed.…”

“…Many research projects propose the use of full electric propulsion [3] or hybrid electric propulsion [4] in these kinds of aerial vehicles. Now, the energy storage systems appear to be the most limiting technologies for the electric propulsion, but the interests of researchers are now focused on the development of new battery technologies [5,6] and in the use of some optimization procedure for the weight reduction of optimization distribution of energy storage systems [7][8][9][10]. Regarding the electrical machine, recent investigations propose the design and development of on-board generation machines, and propulsion electric motors.…”

Nowadays, the reduction of aircraft emissions is one of the industrial targets with a horizon time until 2050. The recent progresses in electrical drives give the opportunity to modify the aircraft propulsion based on thermal engine or gas turbine to a hybrid/full electric one. Some problems must be solved: weight, reliability, and the choice of the best configuration for the electric propulsion. One of the most important aspects to solve is the thermal behavior of power converters and electric motors. This paper proposes an optimization procedure for the design of surface permanent magnet motors used for the aircraft propulsion: the aim of the paper is to investigate the possibility of cooling the motor with only the air flow due to the aircraft speed. The optimization procedure has been solved with the integration of analytical model and finite element analysis and using a differential evolution algorithm.

This paper describes the development of a methodology for air propeller optimization using Bezier curves to describe blade geometry. The proposed approach allows for more flexibility in setting the propeller shape, for example, using a variable airfoil over the blade span. The goal of optimization is to identify the appropriate geometry of a propeller that reduces the power required to achieve a given thrust. Because the proposed optimization problem is a constrained optimization process, the technique of generating a penalty function was used to convert the process into a nonconstrained optimization. For the optimization process, a variant of the differential evolution algorithm was used, which includes adaptive techniques of the evolutionary operators and a population size reduction method. The aerodynamic characteristics of the propellers were obtained using the similar to blade element momentum theory (BEMT) isolated section method (ISM) and the XFOIL program. Replacing the angle of geometric twist with the angle of attack of the airfoil section as a design variable made it possible to increase the robustness of the optimization algorithm and reduce the calculation time. The optimization technique was implemented in the OpenVINT code and has been used to design helicopter and tractor propellers for unmanned aerial vehicles. The development algorithm was validated experimentally and using CFD numerical method. The experimental tests confirm that the optimized propeller geometry is superior to commercial analogues available on the market.
