| description | By taking a typical ducted fan system model as the research object, the unsteady aerodynamics calculation method is established based on slide dynamic mesh technology. After the experimental validation of calculation method, the influence factors of viscous effect, tip clearance and propeller disk location are analyzed based on numerical calculation. The research results show that, the viscous effect embodies the boundary layer interactions between propeller tip and duct, and the calculation accuracy can be improved by considering viscous effect; the tip clearance determines the influence effect of propeller, and the decreasing of tip clearance leads to the increasing of duct thrust; the propeller disk location determines the flow quality and tip clearance, a reasonable location must bring the optimal fairing effect and ensures the tip clearance meeting the design requirements. |
