According to an embodiment of the present invention, a ducted fan ground test device comprises: a driving shaft rotating around a rotation shaft; a motor disposed on a lower portion of the driving shaft to rotate the driving shaft; a ducted fan driven by rotation of the driving shaft; an upper portion coupled to the ducted fan and the motor to receive a load of the ducted fan, the driving shaft, and the motor; a lower portion disposed on a lower side of the upper portion to surround the motor and fixed to the ground to support the upper portion; and a first load measurement portion disposed between the upper portion and the lower portion. A through hole is formed on the first load measurement portion so that the driving shaft can pass through the through hole. The first load measurement portion can measure six components of force with respect to the ducted fan, the driving shaft, the motor, and the upper portion.
