The invention discloses a ducted fan with a high thrust-weight ratio. The ducted fan comprises a ducted front skin, a ducted rear skin, a supporting guide vane, an annular bulkhead, a paddle assembly, a fairing and a driving system. Wherein the duct front skin and the duct rear skin are connected through the annular bulkhead to form a duct main body; the driving system is installed in the fairing, and the fairing is located on a middle shaft of the duct and connected with the annular bulkhead through a supporting guide vane. The paddle assembly is installed on the front edge of the fairing. The ducted fan has the high thrust-weight ratio, the paddle assemblies can bear higher tension, and the ducted fan is high in performance, easy to maintain and suitable for various application scenes.
