Hovering efficiency comparison of rotary and flapping flight for rigid rectangular wings via dimensionless multi-objective optimization

In this work, a multi-objective optimization framework is developed for optimizing low Reynolds number () hovering flight. This framework is then applied to compare the efficiency of rigid revolving and flapping wings with rectangular shape under varying and Rossby number (, or aspect ratio). The pr...

Description
Summary:In this work, a multi-objective optimization framework is developed for optimizing low Reynolds number () hovering flight. This framework is then applied to compare the efficiency of rigid revolving and flapping wings with rectangular shape under varying and Rossby number (, or aspect ratio). The proposed framework is capable of generating sets of optimal solutions and Pareto fronts for maximizing the lift coefficient and minimizing the power coefficient in dimensionless space, explicitly revealing the trade-off between lift generation and power consumption. The results indicate that revolving wings are more efficient when the required average lift coefficient is low (
