In this paper multi-objective genetic algorithms were employed for Pareto approach optimization of turboprop engines. The considered objective functions are used to maximize the specific thrust, propulsive efficiency, thermal efficiency, propeller efficiency and minimize the thrust specific fuel consumption. These objectives are usually conflicting with each other. The design variables consist ...

Ducted propeller is a method on the modification which added duct/nozzle propeller. application aimed to increase thrust, efficiency, and decrease noise vibration. In this research, numerical simulation was conducted using ANSYS Fluent 2020 R2 with k-epsilon solver model. The aim of research analyze effect duct geometry Ld/D (duct length/duct diameter) ratio. done two variations at three differ...

This contribution describes the usage of the ducted fan as a possible actuator of a multicopter vehicle. The measurements are focused on both dependence of forward thrust on current consumption and on dependence of forward thrust on RPM. The measurement results of the ducted fan are compared with the measurement results of a regular propeller. The dependence of actual efficiency on static thrus...

Marine propeller design can be carried out with the aid of automated optimization, but experience shows that a such an approach has still been inferior to manual in industrial scenarios. In this study, optimization is evolved by integrating human–computer interaction as intermediate step. An interactive methodology, based on genetic algorithms (IGAs), developed, where blade designers systematic...

The aim of this study is to present a hybrid algorithm based on two meta-heuristic algorithms named Vibration Damping Optimization (VDO) algorithm and Genetic Algorithm (GA) for solving the stochastic capacitated location-allocation problem. For solving the model more efficiently, the simplex algorithm, stochastic simulation and the proposed hybrid algorithm are integrated to design a powerful ...
