Numerical Investigation of Wing–Multiple Propeller Aerodynamic Interaction Using Actuator Disk Method

Numerical Investigation of Wing–Multiple Propeller Aerodynamic Interaction Using Actuator Disk... This study examines the aerodynamic performances of a wing and multiple propellers through a parametric analysis of wing–propeller interactions. A flow analysis was conducted via simulations based on actuator disk method. The parameters analyzed included the number of propellers, rotating direction, and propeller interval. An increment in the number of propellers increased the wing lift and drag, in addition to the propeller thrust and power. Although the lift-to-drag ratio decreased, the ratio of the wing lift to the propeller power increased. The lift and lift-to-drag ratio of the co-rotating systems were larger than those of the counter rotating systems; however, the lift-to-drag ratio of the latter exceeded that of the former when the number of propellers was seven. An increment in the required thrust increased the lift-to-drag ratio of the counter rotating system in comparison with that of the co-rotating system. Configuration with propellers concentrated at the wing tip increased the lift and drag. However, when the tip propeller was fixed at the wing tip, with the other propellers concentrated in the vicinity of the wing center, the lift increased more, while the drag decreased. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Aeronautical and Space Sciences Springer Journals

Abstract

This study examines the aerodynamic performances of a wing and multiple propellers through a parametric analysis of wing–propeller interactions. A flow analysis was conducted via simulations based on actuator disk method. The parameters analyzed included the number of propellers, rotating direction, and propeller interval. An increment in the number of propellers increased the wing lift and drag, in addition to the propeller thrust and power. Although the lift-to-drag ratio decreased, the ratio of the wing lift to the propeller power increased. The lift and lift-to-drag ratio of the co-rotating systems were larger than those of the counter rotating systems; however, the lift-to-drag ratio of the latter exceeded that of the former when the number of propellers was seven. An increment in the required thrust increased the lift-to-drag ratio of the counter rotating system in comparison with that of the co-rotating system. Configuration with propellers concentrated at the wing tip increased the lift and drag. However, when the tip propeller was fixed at the wing tip, with the other propellers concentrated in the vicinity of the wing center, the lift increased more, while the drag decreased.
