Motivated by a bioinspired optimal aerodynamic design of multi-propeller configuration, here we propose ducted to explore the improvement lift force production and FM efficiency in quadrotor drones through optimizing configuration. We first conducted CFD-based study high-performance duct morphology single-propeller model terms performance volume. The effect configuration on is then investigated tip distance height difference propellers under hovering state. Our results indicate that distance-induced interactions have noticeable impairing but are limited small distances, whereas difference-induced an impact enhancing over certain range. An with minimal appropriate was further examined combination CFD simulations surrogate broad-parameter space, which enables significant both for multirotor, thus provides potential multirotor UAVs.
