Abstract
This study investigates the aerodynamic coupling between propeller slipstream and asymmetric wing configurations with height differences through numerical simulations. Results show that increasing propeller speed enhances lift and drag, intensifies the lift imbalance between the wings, and strengthens the negative rolling moment. The analysis further reveals that increasing the horizontal distance between the propeller and wing alleviates slipstream interference and reduces rolling asymmetry, while increasing the vertical offset enlarges the slipstream-affected region, strengthens pressure differences on the left wing, and amplifies the negative roll tendency. Overall, the findings highlight the strong sensitivity of asymmetric wing aerodynamics to propeller–wing positioning and provide theoretical guidance for the design and control of loitering munitions, missiles, and other asymmetric aerial platforms.
