CFD studies were conducted to evaluate the feasibility of utilizing ducted fan arrays for simulating natural wind environment. A ducted fan capable of generating high-speed wake flow was designed, and an array configuration (termed “wind wall”) was constructed by combining multiple ducted fans. The effects of arrangement patterns and rotational speed distributions on the wake velocity field were systematically investigated. It is found that adjusting the rotational speed of the ducted fan array ena-bles to change the wake velocity, allowing generation of preferred velocity profiles. Comparative analysis between ducted fan arrays and blade arrays revealed that the former exhibits more uniform velocity distribution in downstream wakes, higher air-flow velocity, and lower power consumption, indicating better aerodynamic efficiency of the ducted fan configuration. Fur-thermore, Numerical simulations were performed to analyze the interaction between the ducted fan array and helicopter rotor. Under the influence of ducted fan array wake, helicopter blade thrust fluctuates more dramatically, and time-averaged blade thrust become larger accompanied with more shaft power consumption.
