The stability performance analysis of ducted fan UAV based on fluent

In this paper the fluent software was used to solve the stability of ducted fan UAV problems. The researchers calculated, programming, before and after repeated treatment and so on inputs, inefficient labor was reduced. More energy and time was considered into the nature of the problem, optimization algorithm selection and parameter setting, so the work efficiency was improved. The pneumatic parameter of the wing was introduced importantly. The basic control parameters were set, and the posture of wing was simulated in the 0-15 degrees. Finally, the results showed that the stability of the ducted fan UAV in the 0-10 degrees was better than after 10 degrees, the reliability of aerodynamic parameters was decreased rapidly.
