The integrated ducted structure significantly enhances the aerodynamic performance of duct–rotor system, reducing noise and enhancing rotor safety. However, in coupled parameters duct are crucial to its characteristics. This study employs a Computational Fluid Dynamics numerical analysis investigate duct–rotor, focusing on related blade’s relative position tip gap. Additionally, our research delves into fundamental mechanisms key parameters, such as blade gap, elucidating their role optimizing duct–rotor’s aerodynamics. results emphasize critical gap influencing duct–rotor. Notably, when exceeds 3.0% duct’s radius, advantage provided by is insufficient offset loss rotor’s performance. As 7.0% deterioration caused gradually stabilizes. Furthermore, influence relatively minor. placing at exit proves advantageous for improving distribution characteristics system.
